RAFI has developed a multifunction armrest control system for the new tractor generation from agricultural machinery manufacturer Massey Ferguson, a member of the ACGO Group. The scalable solution is available in a wide range of variants so that customers can choose between twelve configuration levels with different function ranges and joystick features. To achieve this high degree of customization, RAFI designed around 80 new injection molding tools and set up a production line with a new assembly process. In the one-piece-flow process, one assembly worker assembles the entire armrest along all stations, supported by visual instructions and pick-by-light technology. All the components and work steps can be seamlessly tracked. RAFI manufactures the armrests almost exclusively using in-house developed technologies, product groups, and its own production processes. The armrest system was developed in accordance with DIN EN ISO 25119 – AgPL c. Safety-critical operating elements for the vehicle and hydraulic control system feature a redundantly designed hardware as well as diagnosis-capable software to reliably maintain error-free functionality. The up to four integrated joystick variants are based on different JOYSCAPE technology platforms developed by the HMI expert. Contactless, wear-free Hall sensors take care of motion detection. They have an operating life of at least five million actuation cycles. Integrated shield plates protect the sensors against any influence from external magnetic fields. Innovative single-axis linear joysticks with latching function are available for the control of additional hydraulic functions. The silicone keypads contain RAFI MICON 5 tactile switches. Arranged in an ultra-compact row of pushbuttons, they deliver distinct tactile feedback. High-quality gold contacts ensure permanent switching reliability. For safety-critical functions, RAFI uses its fail-safe, redundantly designed MICON 5 Safety micro-switches.

RAFI, one of the world’s leading suppliers of solutions for human-machine communication, will present a selection of its extensive product portfolio at this year’s SPS in Nuremberg from November 14 to 16. At its booth in Hall 8/128, the manufacturer will display not only a wide range of electromechanical actuators, but also haptic input solutions for touchscreen operation. The pushbuttons, rotary/push encoders and finger wheels from the FLEXSCAPE series are mounted on closed touchscreens without any need for cut-outs or holes. They enable tactile operation with haptic feedback and reliable finger guidance. Another RAFI focus at the SPS is the KIS.ME Plug&Play system for easy digital WLAN connection of previously unconnected work, logistics, and production areas. The KIS.ME hardware consists of control boxes with two illuminated pushbuttons which can be legended, as well as RGB signal lamps. The KIS devices are set up via the KIS.MANAGER web platform. They are individually configured by applying simple logical rules to trigger external events such as color states of the signal lamps or actively switched outputs from the control boxes. A virtual dashboard displays key figures and performance indicators. All connected KIS devices can be mapped as digital twins on a shopfloor plan and controlled via their digital equivalents. The third RAFI focus at the trade show is the company’s comprehensive electronic engineering and manufacturing services. As one of Germany’s ten largest E˛MS suppliers, RAFI covers the entire contract production process – starting with material procurement, through PCB assembly, creation and implementation of test concepts, right up to logistics and life-cycle services. The RAFI team of experts is looking forward to welcoming lots of trade visitors to its SPS booth in Hall 8/128.

At the Agritechnica 2023 in Hanover from November 12 to 18, RAFI will highlight new developments and innovative solutions for the effective control of agricultural machinery and vehicles. The company will present its product and service portfolio on Stand D27 in Hall 17. There will be a particular focus on RAFI’s state-of-the-art, rugged GLASSCAPE control systems. The capacitive touchscreens come with impact-resistant glass panels, high protection ratings up to IP68, and finely-tuned sensors. The glass sensors can also be used with gloves, and special filter algorithms prevent false actuation triggered by accidental touch. The optical bonding used in these systems guarantees optimal display quality and legibility even in difficult light conditions such as direct sunlight. Even without visual contact, operators of mobile machinery and vehicles can rely on tactile feedback and precise finger guidance that allow them to fully concentrate on their surroundings. Haptic elements from the FLEXSCAPE series – pushbuttons, rotary/push encoders, and finger wheels – are mounted on the touchscreens without any need for cut-outs or holes. This creates adaptive operating systems with perfect functionality, and the display surface remains fully stable and tight. Displays with TWIN TOUCH technology combine touch and force sensitivity. Manufacturers can define the specific pressures required to actuate the various operating elements. This combination makes it possible to implement a functionally reliable touchscreen up to AgPL d. The HAPTIC TOUCH system provides a parameterizable force feedback for accurate conveyance of the tactile specifics of all tactile switches, sliders, and other input elements. RAFI can also customize these systems with a wide range of FLEXSCAPE actuators. The RAFI trade show crew is looking forward to exciting talks and expert discussions during the event.

With its GLASSCAPE range of touchscreens and control panels, the RAFI Group is a leading manufacturer of customer-specific touch control systems for industrial applications. The HMI specialist manufactures all the embedded control units (ECU) for its solutions in-house. This guarantees short development times and an optimal cost-benefit ratio at every stage. The program, which RAFI continually further develops, previously offered a choice of four ECU platforms in increasing performance classes from ECO-ECU (Cortex M0/M4), BALANCE-ECU (i.MX6SX), POWER-ECU (i.MX6Dual/Quad) to ULTIMATE-ECU (i.MX8Quad). Now the HMI specialist has completed the range with the high-performance XTREME-ECU, which uses the x86-based “Elkhart Lake” platform with a processor from Intel’s Atom-x6000E line. The chip architecture optimized for industrial applications comes with a wide range of advantages. They include low power consumption that enables fan-less operation, a wider temperature range of -40°C to +85°C, and support of standard operating systems such as Linux and Windows. As a result, XTREME-ECU significantly reduces the outlay for application-oriented software implementation compared to previous ARM-based ECU versions. What’s more, HTML5 applications also run smoothly on the system. XTREME-ECU is available as a SMARC plug-in module. This means that for the first time device manufacturers can offer their products as x86 systems for industrial applications with fan-less design and long-term availability.

To drive its further expansion in the Eastern European economic area, HMI expert RAFI signed a contract with DACPOL in April 2023, making it the company’s new distribution partner for the Polish market. Founded in 1992 in Piaseczno near Warsaw, the company specializes in selling electrical components for power electronics, process automation, and electrical and energy technology. DACPOL supplies customers in a wide range of industries with quality products from numerous leading producers. Its customers include manufacturers of drive units, welding machines, power supply devices, electrical equipment for traffic systems, vehicles, and consumer electronics – but also research institutes, service centers, and commercial companies. By adding RAFI products to its sales range, the distributor is expanding its portfolio and increasing the availability of high-end control components, actuators, and switching elements in the Polish region. The two companies made their first joint appearance in April at the Warsaw Pack international trade show for packaging technology and materials. Visitors were particularly interested in the RAFI actuators displayed for the first time on a new sample panel on the DACPOL stand.

RAFI is replacing its practice-proven MICON 5 tactile switches with a new series. The MICON 5 S range is even more robust. The outer dimensions remain the same, at just 5.1 mm x 6.4 mm and an installation height of 3.85 mm. However, an optimized sealing system upgrades the new key switch generation to IP67 degree of protection. This makes the tactile switches also suitable for use on PCBs protected after assembly by casting, painting, and nanocoating. Other qualities that distinguish the new series from the MICON 5 are a maximum operating temperature that is 35°C higher and a temperature resistance of -40°C to +125°C. This meets current automotive industry standards. Just like in the predecessor range, high-quality gold contacts ensure permanent switching reliability. MICON 5 S is available in both SMT and THT types and in versions with operating forces from 1.5 N to 7 N. Depending on the operating force, the lifetime is up to one million actuation cycles. RAFI ensures functional reliability with 100-percent testing of the force-travel characteristic curves. For installation of the key switches under overlays, the extensive accessory range offers round and square plungers in various dimensions and illumination variants, indicator fields for ring lighting, and bezels in all basic colors.

With the MICON 5 S, MICON 5 SL, and MICON 5 SAFETY series, RAFI has launched a new generation of robust, ultra-small tactile switches. The extremely compact micro-switches measure just 5.1 x 6.4 x 3.85 mm. Thanks to their optimized sealing system, they achieve IP67 degree of protection and can therefore be installed on PCBs protected by casting, painting, or nanocoating. The extreme temperature resistance from -40°C to +125°C meets current automotive industry standards. High-quality gold contacts ensure permanent switching reliability. The micro-switches are available for operating forces of 1.5 N to 8 N as well as in the extremely long-life MICON 5 SL version. With an operating life of up to ten million actuation cycles, the SL switches are designed for tough applications, e.g. in joysticks and other control devices subject to high stress. The third option in the range is an enhanced-safety version. With identical dimensions, the MICON 5 SAFETY series incorporates two potential-free, separate NC and NO contacts. Due to the two-channel contact system, these models are ideal for safety-critical applications that meet the functional safety requirements of IEC 61508, DIN EN ISO 13849, IEC 62061, IEC 60601, DIN EN ISO 25119, DIN EN 50128, or ISO 26262. Characteristic of all MICON 5 variants is their distinctive tactile feedback. The model series are available with SMT and in some versions THT. The media-resistant design makes them ideal for automated PCB assembly and sealing. There is also an extensive range of accessories with compatible plungers, keycaps, and illumination solutions for all use cases.

RAFI is currently investing in two major projects: In April 2023, the company will begin construction of a new building in Bad Waldsee with infrastructure that is both energy-efficient and low-consumption. The new facility is a combined, state-of-the-art office and production building. It will house the operating equipment for plastics and automatic machine production, metal processing, tool and die making, and tool and die development. A number of classrooms and the facilities for basic training in metalwork will be combined into an impressive apprenticeship, teaching, and further training center. “These projects represent an investment in the sustained further growth of the entire RAFI Group,” explains Dr. Lothar Seybold, CEO of the RAFI Group. CFO Lothar Arnold adds: “The construction of a new production plant in Bad Waldsee is a clear statement of commitment to the region as a business location. It creates new, crisis-proof jobs here.”
The second major project is the revamp of the location in Berg. It was launched in 2022 and RAFI has now completed the first construction phase. As part of its growth strategy, RAFI is investing a sum in the high two-digit millions for the three-year renovation and energy-saving modernization project. It involves successively fitting the buildings with new, climate-friendly roofs, façades, and glazing. The physical effects are expected to deliver energy savings of up to 45% and a significant reduction in CO2 emissions of around 340 tons per year. The first construction phase for Building A has been successfully completed. Now the nine-story block has new external insulation plus a rear-ventilated façade made of certified recycled aluminum. From an energy standpoint, all components are designed for maximum reduction in CO2 emissions.

RAFI’s tried-and-tested RACON 8 and RACON 12 S tactile switch series are now available in a temperature-optimized version intended for various PCB protection procedures: Thanks to the additional sealing system, the new RACON ST tactile switch series (sealed & extended temperature range) is ideal for casting, lacquering and nanocoating of correspondingly equipped PCBs. In addition, RACON ST sets itself apart from conventional switches thanks to its 35°C higher maximum operating temperature and, with a temperature resistance of -40°C to +125°C, it also meets the current standards of the automotive industry. None of the usual RACON tactility is lost due to the extended durability features. Like the existing series of key switches, the ST switches have compact dimensions of 12 mm x 12 mm or 8.4 mm x 8.4 mm and are available in SMT or THT versions. High-quality gold contacts ensure permanent switching reliability. To meet the various demands of tactile feedback, the switches are available in types for operating forces of 2.5 N to 9.7 N. For applications underneath membranes, the range of accessories includes round or square plungers in twelve lengths ranging from 1.4 mm to 7.6 mm.

MICON 5 tactile switches from RAFI are now also available in a new MICON 5 SAFETY version with a two-channel contact system. With a base of just 5.1 x 6.4 mm and a height of 3.85 mm, MICON 5 SAFETY key switches come in the same dimensions as MICON 5 key switches, but integrate two potential-free, separate NC and NO contacts. This means the micro key switches enable an especially cost-effective and space-saving design in applications that comply with functional safety standards such as DIN EN IEC 61508 (basic functional safety standard), DIN EN ISO 13849 (safety-related parts of control systems), DIN EN IEC 62061 (safety of control systems), DIN EN IEC 60601 (medical electrical equipment), DIN EN ISO 25119 (control systems for agricultural and forestry machines), DIN EN 50128 (rail applications), or ISO 26262 (road vehicles). Due to the optimized sealing system, MICON 5 SAFETY key switches comply with IP54 and/or IPx7 degrees of protection. With a temperature resistance of -40°C to +125°C, they also meet the current requirements of the automotive industry. For PCB assembly, the key switches feature SMT connection and are suitable for casting, painting, and nano-coating. Just like RAFI’s standard versions, MICON 5 SAFETY key switches feature a gold-contact system for reliable switching, excellent tactility, and a long operating life. The key switches are available for various operating forces and, depending on the version, they achieve up to one million operations. Thanks to the identical dimensions of the two ranges, the extensive MICON 5 accessory program of plungers and keycaps is equally suitable for MICON 5 SAFETY key switches.

Last December, the RAFI Group’s Chinese branch, RAFI Electronics, moved into its new production facility in Shanghai. In the new factory in Quingpu, RAFI Electronics has a production area of 7,800 m˛, of which 4,600 m˛ is a clean room area for the production of electronics using SMT and THT assembly. The HMI specialist will use five SMT lines to produce mainly electronics for the medical technology, robotics, and automotive industries. The other 3,200 m˛ of production space is allocated to product assembly. With cutting-edge energy supply technology, RAFI Electronics also meets its green responsibilities: Installed on the roof is a solar power system with an area of 2,200 m2 and a capacity of 200 KVA. It powers a micro grid with an energy storage system.
On the opening date on December 22, 2021, Zhu Mingfu, Director of the Standing Committee of the People’s Congress of Qingpu District, visited the new factory and praised the sustainable development of the industrial park, which he called a win-win situation for all stakeholders. Thanks to the new factory, RAFI Electronics can not only considerably expand its production capacities, but also moves closer to the Asian markets. Simultaneously, RAFI customers in Europe and the USA benefit from the good price-performance ratio the manufacturer achieves by purchasing components in China. On this basis, RAFI with its production locations in Germany, Italy, Hungary, the USA, and China, can offer ideal solutions for every customer requirement.

On the occasion of its 30th anniversary this year, RAFI Hungaria Kft. looks back on three decades of success. In 1991, RAFI founded RAFI-BBP in Mezotúr, Hungary, to expand its assembly capacities for electromechanical operating elements. Even in its first year, the number of employees increased from 5 to 21. Starting in 1995, RAFI-BBP gradually expanded its activities to include the manufacture of electronic and opto-electronic assemblies. The company also introduced quality management in compliance with ISO 9002. After continuous expansion of the manufacturing facilities and soldering systems, the company also added assembly of electronics products for the automotive industry to its range. In 2000, a new production unit was built, doubling the operating area. At the same time, the company adopted a process-oriented QM system according to EN ISO 9001:2000. Over the following years, the company expanded its production capacities by installing new high-performance assembly lines for electronic assemblies as well as a third production unit with a total useful area of 2,200 m˛. It also introduced a quality management system for medical products that complies with ISO 13485. Today, RAFI Hungaria operates production areas totaling 7,760 m˛ and has more than 500 employees. There has always been a focus at the company on training and further training to ensure a qualified current and future workforce. This prompted it to join forces with local technical school Teleki Blanka to establish a highly practical training program for electronics technicians. Furthermore, RAFI Hungaria cooperates with the University of Debrecen in its dual-studies program by offering opportunities for works students.

In October, RAFI and BeeWaTec agreed on a partnership for the sale of RAFI’s innovative KIS.ME communication and process control system. BeeWaTec is a solution provider for lean manufacturing, agile production and Industry 4.0. In the future, its customers will be able to directly order all KIS.ME hardware components and services, including application-specific system configuration, from BeeWaTec. KIS.ME stands for “Keep it simple. Manage everything”. The smart Plug&Play solution enables fast and easy digitalization of previously unconnected work, logistics, and production areas. The system is based on WLAN-capable control boxes and signal lamps with integrated I/Os which are networked via the KIS.MANAGER web platform. They are configured to the specific application in each case using simple logical rules. This enables customers to implement transparent signaling processes in previously non-digitalized production or logistics applications. It also allows easy integration of manual workplaces, remote delivery zones and older machines into the cloud-based control system. The data from these application areas is then captured in the cloud system and displayed in KIS.MANAGER for analysis. KIS.ME users can access KIS.MANAGER through a central web account at RAFI. As an exclusive partner of RAFI, BeeWaTec can offer its customers this service together with the required hardware from a single source. “We are delighted to have gained such a renowned specialist for manufacturing systems as BeeWaTec to be our sales partner” explains Axel Zauke, Key Account Manager at the RAFI Group. “The interest of BeeWaTec in our product also shows that it offers the right solution for many digital retrofitting jobs.” “In our view, previously no convincing solutions were available for the efficient collation of data from unconnected production or logistics areas and its transfer to the control system,” says Joachim Walter, COO of BeeWaTec. “KIS.ME closes this gap. Its ingenious concept also makes implementation very easy.”

During the typical working day of a floor cleaner, the control technology must be able to withstand a good deal of wear and tear and, in addition to mechanical stress, must also withstand many a rustic actuation. That’s why Dr. Gansow Gmatic AG uses robust, easy-to-install switches from the RAFI RAMO 22 series as the control units in its high-quality Gmatic and Rotan scrubber dryers. The actuators, sized for an installation opening with a diameter of 22.3 mm, are very easy to install and connect. As standalone solutions in the completely enclosed mono-housing, they achieve a high degree of protection up to max. IP69 without the need for further seals. Thanks to direct wiring via M12 terminals, no time-consuming individual wiring is required. Correct connection is possible without specialist knowledge of electrical engineering. Service and maintenance work is also reduced, because the connections can be easily disconnected and reconnected as required. Switching states and settings are indicated clearly by signal lamps, illuminated switches and twist grip labels. The energy-efficient LED technology is robust and lasts for the lifetime of the machine.

Today, the energy consumption of heating radiators is usually recorded and calculated fully automatically using smart meters. These devices must function maintenance-free and without battery replacement over an operating life of ten years. As a provider of electronic engineering and manufacturing services (E˛MS), RAFI produces large quantities of these high-value electronic meters and additionally supports metering companies in optimizing designs for low-power applications. To ensure its customers can rely on the maintenance-free functioning of its devices, RAFI insists on appropriately long storage and supply periods. This is why the E˛MS service provider exclusively procures its lithium batteries for low-power applications from suppliers who guarantee an extended minimum service life of 12.5 years. RAFI additionally carries out in-house random checks of the battery cells. All handling and manufacturing processes are designed to avoid wear-inducing stress on the batteries. Apart from battery quality, the energy-saving function is crucial for the service life of low-power electronic devices. RAFI recommends energy-efficient components and optimizes PCB layouts and intended transmission performance. Engineering solutions and high manufacturing quality prevent leakage currents. To protect against electromagnetic interference, RAFI takes suitable EMC precautions, if necessary including shielding.

Joachim Tosberg, Life Cycle Manager at RAFI, has been re-elected for the second time as a Board Member of the Component Obsolescence Group Deutschland (COGD). Since 2017, RAFI has been a member of the association, which currently comprises more than 160 companies, and is working there on recommendations for action and guidelines for best-practice solutions in dealing with obsolescence. “The current focus is increasingly on the topic of sustainability”, explains Tosberg. “With the SCIP database, the EU has further tightened the requirements according to RoHS and REACH, obliging manufacturers to report the use of substances of concern in a Europe-wide database. This not only concerns electronic components, but also synthetic materials, metals, paints, and much more. It is therefore all the more important to counteract the accelerated discontinuation of components and materials through proactive selection of the most durable, permanently available materials and components possible. Through our involvement in the COGD, we can help shape the conditions and structures for sustainable obsolescence management in association with other industry players and make product development more resource-efficient overall.” One of the key tasks of COGD, which leading industrial companies as well as numerous component manufacturers and distributors belong to, is to develop strategies and methods for proactive obsolescence management to be able to adapt products and production processes at an early stage where there are discontinued components and make alternatives available. Apart from exchanging information in seminars, workshops and lectures, the association is also involved in standardizing obsolescence management and has introduced Smart-PCN, an overarching standard for the communication and automatic processing of product discontinuations.

Due to its extremely compact design and unique short operating stroke of just 0.55 mm, the KN 19 membrane-covered mains switch from RAFI can be integrated directly into low-profile data entry systems. Therefore, the tactile switches for AC rated voltages of 250 V and DC rated voltages of 12 V to 50 V can replace conventional mains switches without the need for cut-outs in the unbroken overlay. In the case of DC rated voltages, the rated current is 6 A. KN 19 switches are available in a single-pole version with a normally-closed contact plus a normally-open contact and in double-pole form with two normally-open contacts. As an alternative to installation under the overlay, the switch can also be fitted with keycaps from the RAFI RK 90 range. The standard overall height of 9.7 mm means the KN 19 can be combined with other RAFI tactile switches and electronic components on a single PCB. The manufacturer supplies the switches for grid spacing of 19.05 mm x 38.1 mm, also in illuminated types.

RAFI has extended its E-BOX product family for remote-location emergency stop buttons by a version with an additional control component. Apart from the emergency stop function, the slimline boxes can additionally feature either a pushbutton, a selector button, or a keylock switch from the RAFIX 22 FS+ control component series. This means they offer a further control option for remote applications without the need for extra cables. The housing dimensions of 109 mm x 40 mm x 29 mm make the E-BOX range ideal for attachment to 40-mm profile rails. The mounting clip is easy to attach to the profile rail groove via the single screw hole, then the E-BOX is simply snapped on without the need for tools. Alternatively, two screw holes are available for easy mounting on flat surfaces. RAFI supplies its E-BOX ready for connection. The M12 terminal means the control unit can be put into operation immediately without any need for wiring. The E-BOX comes in IP65 degree of protection and is designed for use in a temperature range of -25°C to +70°C.

Just like all the control components from the RAMO range from RAFI, the illuminated pushbuttons in the RAMO T series are available for mounting hole diameters of 22.3 mm or 30.3 mm. While the RAMO 30 T comes as a standard with stainless steel bezel, RAFI now supplies the slimmer RAMO 22 T models not only in the classic black plastic housing, but also with a metallized front ring. RAMO T models are available in a wide choice of bezel colors. They stand out for uniformly illuminated button surfaces as well as a noticeable tactile feedback. The switching elements are integrated tactile switches from RAFI’s MICON 5 range with high-quality gold contacts, which guarantee switching reliability and a long operating life. For custom legending of the button bezels, RAFI offers the FLEXLAB legending system with labelling sheets either pre-printed or for printing by the customer. Due to their closed mono-housings with IP 66 or higher degree of protection, RAMO control components are ideal for use in or retrofitting into decentral applications. The easy connection via M12 plug terminals makes extra wiring unnecessary and allows installation by untrained personnel.

With new types of its outdoor-capable E-BOX control units and TILTED DIAMOND+ signal lamps, RAFI now offers two innovative product families for the IO-Link interface. As a control box with an IO-Link interface, the E-BOX IO-LINK makes it possible to integrate switches and key switches for simple control tasks in any field bus. The slimline, rugged units feature IP65 degree of protection. The M12 terminal means even untrained personnel can quickly install them and put them into operation. The IO-Link device identification prevents errors because incorrectly installed devices are reported to the control unit. The IO-Link Master automatically transfers saved parameters to replacement devices. Thanks to integrated tactile switches from the MICON 5 series, the illuminated pushbuttons of the E-BOX provide excellent tactile feedback. They can be customized via IO-Link with a large range of functions to suit the application. Included among the options are night mode with various brightness levels, the flexible choice of white, red, green, blue, and yellow illumination, or three RGB colors that can be selected by the customer. Furthermore, the buttons can be configured with four different flashing modes for different application cases. RAFI supplies the E-BOX IO-LINK equipped ready for commissioning with one or two switching or indicator elements from the RAFIX 22 FS+ series. For individual marking of the control components, printed or unprinted FLEXLAB labelling sheets are available. With their compact dimensions of 123.2 mm x 40 mm x 35.6 mm, the control units are ideal for assembly on 40 mm profile rails on production lines or safety fences. The accessories include a fixing clip that can be attached to profile rail grooves and other mounting surfaces. The E-BOX simply snaps onto the clip. RAFI has also released an IO-LINK version of its RGB-LED signal lamp from the TILTED DIAMOND+ series. Thanks to its M12 terminal and IO-Link parameterization, it is also fast and easy to install. Apart from freely configurable night settings and illumination colors, the TILTED DIAMOND+ IO-LINK comes with further options. It can signal application-specific alarms or machine statuses with eight different flashing modes such as single flashes, continuous flashing, or pulsating light. What distinguishes the signal lamps are exceptional brightness, vibration resistance with IP66 degree of protection, no need for maintenance, and the striking dome-shaped bezel design. The diamond-shaped lenses arrayed all round give the bezels excellent illumination, clear signal colors, and top visibility over large distances. The accessories available include support tubes in various lengths and shapes and a mounting base.

RAFI is expanding its rugged RAFIX 22 FSR control component range with a signal lamp featuring a stainless steel collar with IP65, IP67 and IP69 degree of protection to the front side. The integrated red/green LED can indicate three signal statuses. The translucent indicator is a neutral white in standby mode, green indicates regular operating condition, and red signals faults. The convex signal indicator makes it easy to see the signals from different directions and distances. The lamps have a diameter of 31.3 mm and an installed height of 12.2 mm. Like all RAFIX 22 FS/FSR control and signaling units, they fit standard 22.3 mm installation openings. The mounting depth is 25.45 mm.

RAFI uses its own standard ECUs in customer-specific touchscreens and control panels. This has allowed us to quickly realize a large number of projects for industry, agricultural and construction machinery, or medical technology to date, while saving resources. RAFI develops and produces the ECUs and touchscreens including sensors in-house, enabling it to ensure continuous long-term availability and quality of the systems. RAFI covers a wide range of applications with its ECU program. The RAFI control unit in the “ECO-ECU” series with ARM Cortex-A5 or M3M4 processor was developed for simple, cost-sensitive operating and display tasks, with max. 800 x 600 pixel resolution. Control units in the “BALANCE-ECU” model range with a single ARM Cortex-A9 processor cater for higher operating requirements and resolutions of up to 1920 x 1080 pixels. The even more powerful “POWER-ECUs” with ARM Cortex-A9 in Dual or Quad design are used for touch user interfaces with animated graphics and resolutions of up to 1920 x 1200 pixels. With the newest “ULTIMATE-ECU” series, RAFI is raising its range of Embedded Control Units to the next performance level. The “ULTIMATE-ECU” is designed for touchscreen applications with high quality 3D visualization, multi-touch inputs, and Full-HD screen resolutions on up to 24″‚ display diagonals. Its centerpiece is an ARM Cortex-A35, i.MX8QuadXPlus processor from NXP with Yocto-based embedded Linux core and a clock frequency of 900 MHz. As standard, the “ULTIMATE ECU” offers two Gigabit-Ethernet interfaces, a USB 3.0 interface and three CAN-Bus interfaces. The new ECU generation has already been proving its worth as a central computer for mobile processing machines in several projects.

With its JOYSCAPE joystick platform and extensive add-on options, RAFI is able to implement custom control solutions for any application purpose and with optimum ergonomics for the job. Four differently dimensioned platform modules cover all use cases in various industries such as mechanical engineering, medical technology or construction and agricultural machinery. For heavy-duty applications, RAFI uses its JOYSCAPE ROUGH model with a shock resistance of 110 Nm. Ergonomic multifunction joysticks developed in close cooperation with the customer ensure easy and intuitive operation even under the toughest conditions. For challenging but less rugged applications, the joystick platform offers the versatile JOYSCAPE MULTI basic model. This version is also available with customized handles. Depending on requirements, the manufacturer can install thumb joysticks, rockers, pushbuttons and other actuator or signal elements. Where installation space is tight and control tricky, JOYSCAPE BASIC with free tilt function in the x/y plane is the optimal solution. The smallest model in the range is the compact thumb joystick JOYSCAPE TINY. It is designed for flexible integration into joystick handles or other control elements. All variants use wear-free 3D Hall sensors for motion detection. They have an operating life of up to five million actuation cycles. For high safety requirements, the sensor system is also available in a redundant design. The ferromagnetic steel housing effectively shields the sensor system, providing additional ruggedness. The joysticks are fully manufactured in-house and configured with various rockers, angles of deflection, operating forces or control components. This is how RAFI ensures seamless integration of its products into diverse customer systems. Optional extras are also available such as illuminated handles for work at night, capacitive hand detection to avoid operating errors and easy-clean folding bellows for hygienically sensitive areas.

RAFI’s selector switches in the RAMO S series feature a completely closed housing with IP65 degree of protection and M12 terminals. That means they do not need any additional housing. Therefore, these switches – like all control and indicator elements in the RAMO 22 and 30 series – are ideal for cost-effective construction and retrofitting of decentral applications. Depending on the series, the switches are designed for mounting holes with diameters of 22.3 mm or 30.3 mm. Alternatively, the RAMO EDGE fixing angle offers the option of placing the switches offset on any surfaces or on 40-mm profile rails. The RAMO S series comprises selector switches in different types with rotating angles of 40°, 60° or 90°. Depending on the model, the levers can be switched to up to three positions and the actuation functions momentary contact, latching or momentary contact and latching. The contact functions available are 1NC+1NO, 1NO and 2NO. The rugged selector switches are also available in illuminated versions with translucent handle marking. The simple connection with standard M12 plug terminals makes wiring unnecessary, so RAMO switches, key switches and lamps can even be installed by untrained personnel. The components in the RAMO 22 series feature black front rings in synthetic material, while the RAMO 30 versions have flat stainless steel bezels.

HMI specialist RAFI has been producing capacitive control units for the HAMILTON-C6 mobile respirator station from Swiss medical technology manufacturer Hamilton Medical for around four years. This company, which has specialized since 1983 in the development of intensive respirator systems, ranks among the leading suppliers of intelligent high-end devices. Currently, manufacturers and suppliers face major challenges due to the coronavirus pandemic and the resulting surge in demand for respirators. But, thanks to foresighted planning and management of manufacturing capacities, RAFI has succeeded in increasing production of its control units far beyond the usual volumes. “As soon as the first alarming reports came in, we started thinking about how we could boost delivery capacity if necessary,” explains Max Mattes, the responsible RAFI Account Manager for the Systems business unit. “Our Purchasing department pro-actively contacted the relevant component suppliers. Our control units are an essential feature of the respirators. So of course we feel that RAFI has an indirect responsibility for ensuring the supply of life-saving medical devices.” The HMI manufacturer produces the control units entirely in-house. To increase the quantities at short notice, it had to flexibly adjust capacities in its production department and re-organize its order processing. The year before last, the company established its own clean room system for the production of glass sensors for capacitive touchscreens so that it could remain independent from Asian suppliers. Apart from the 17″ touch sensors for the Hamilton respirators, RAFI also produces the diagnostic electronics and integrates the touch controllers on its own assembly lines. The front glass panels are also printed and fitted with electro-mechanical keypads in RAFI’s own facility. The hygiene-compliant silicon key switches are inserted into openings cut into the front glass panels, and snap-action contacts are installed underneath the actuators. Development and production of the control units, which RAFI supplies as fully assembled, ready-to-use assemblies, comply with the EN ISO 13485 medical standard. “To meet the acute demand, we had to restructure a lot of our sequences. Obviously, all processes that are critical for the operating surfaces of the respirators come first right now,” says Mattes. “But of course we’re still doing everything to make sure all our customers get their supplies on time.”

The RAFI RAMO range includes robust USB 3.0 and RJ45 feedthroughs for front panel installation or standalone setups, in addition to switches and signal lamps with M12 plug terminals. The RAMO F feedthroughs feature an IP65 degree of protection when the protective cap is closed. RAMO EDGE 90° mounting angles allow for remote mounting of individual feedthroughs and other RAMO components on vertical surfaces or on 40-mm profile rails. RAFI especially designed all RAMO 22 and 30 components for individual housing-free mounting at remote locations. Featuring single-part, fully enclosed mono-housings, the feedthroughs can be installed in 22.3 mm or 30.3 mm mounting holes without an additional housing, just like the series‘ pushbuttons, emergency stop switches, selector switches, keylock switches, and LED signal lamps. RAMO 22 components feature black plastic front rings. RAMO 30 versions have a flat stainless-steel bezel.

The keylock switches from RAFI’s RAMO K range offer a rugged, fast-assembly control solution for decentralized applications where it is necessary to lock critical actuation functions. Like all control elements and indicators from the RAMO program, the keylock switches do not require any additional installation housing. The completely closed housing with IP65 degree of protection and the M12 terminal ensure rapid on-site assembly without time-consuming manual wiring. Thanks to the Plug&Play connection via standard M12 plug terminals, even untrained personnel can commission the devices from the RAMO 22 and RAMO 30 series for 22.3 mm or 30.3 mm mounting holes. With the RAMO EDGE 90° mounting angle for individual mounting, the switches can also be mounted as required on any vertical surface and on 40-mm profile rails. RAFI supplies the RAMO K keylock switches in a variety of types with rotating angles of 40°, 60°, or 90° as well as various rotating angle shapes. The switches are also available with distinctive haptic qualities for up to three switching positions with momentary contact, latching, or combined actuating functions. The RAMO 22 and 30 models differ not only in their dimensions, but also in design, with black front rings made of synthetic material or flat stainless-steel front rings. RAFI presents the RAMO range of operating and indicating elements as well as feedthroughs at www.rafi.de/en/ramo-2230.

RAFI exhibited its developments and products in the field of control components, system components, and capacitive input technologies at the 2019 SPS trade show in Nuremberg, Germany. Introducing Smart Solutions, RAFI presented a new technology concept for wireless condition and progress signaling for use in intralogistics processes. The portal-based system intelligently links mobile pushbutton units with freely positionable signal lamps via WiFi. What makes Smart Solutions stand out are the universal application options, simple use, and fast setup. The pushbutton boxes and signal lamps integrate WiFi interfaces. The units come with an unambiguous ID and a USB port connector. To start up the system, the user simply logs in to the RAFI portal once, defines the linking logic required, and saves a digital twin of its application. Another RAFI highlight at the trade fair was a representative cross-section of the company’s solutions for renowned customers in machine and plant engineering, automotive and commercial vehicle manufacturing, communications electronics, and household appliances. The product range on show covered everything from handheld units and operating panels to electronic assemblies and fully integrated complete solutions for commercial vehicle control. RAFI is not only one of Germany’s largest contract manufacturers of electronics, but also ranks among Europe’s leading manufacturers of capacitive industrial touchscreens. With its Twin Touch technology, RAFI has launched a new generation of industrial touch data entry systems featuring combined touch and force detection. This solution prevents accidental input errors and opens up scope for new input levels. It means users can select or set function menus or parameters by varying the pressure exerted on the display. Another innovation, the mechanical key switches and finger guidance solutions in the FLEXSCAPE range enable reliable blind operation of touchscreen functions. The touchscreen keeps its high degrees of resilience and ingress protection because the actuators are fixed without openings or holes in the surface. Other areas of the trade fair stand were dedicated to compact embedded control units (ECU) for HMIs and control systems, new basic models for the JOYSCAPE joystick platform, and RAFI’s successful switch and key switch programs.

RAFI expands its GLASSCAPE portfolio of industrial-grade capacitive touchscreens, introducing the new TwinTouch input technology, which in addition to touch evaluates the force of inputs. Combining touch and force detection, TwinTouch significantly increases operational safety. Capacitive switches and fields in the touchscreen can be configured to require a defined pressure force for touch commands. This helps prevent accidental input through unintended contact with the screen. The switching thresholds for the applied pressure can be individually adjusted via software. At the same time, the combined evaluation of touch and mechanical force enables an implementation of additional input levels. For instance, pressing a screen button for a prolonged time may activate a context menu, or applying different amounts of pressure may be used to adjust parameter values. The TwinTouch system with trackless pressure measurement ensures reliable IP65 ingress protection.
