RACPRO1-4SP e-Fuse Series
The RACPRO1-4SP series are 4-channel electronic fuse (e-Fuse) load switches designed to provide independent overcurrent protection for each channel. They feature real-time current monitoring and LED status indicators to simplify diagnostics. Each channel operates independently, ensuring system reliability even when faults occur. The design includes sequential power-up to limit inrush current and reverse-sequence shutdown to prioritize essential loads. Adjustable overload modes allow flexible system configuration. These e-Fuses support 5A or 10A per channel, with a 150% power boost for up to 5s to handle temporary load surges. For short-duration overcurrent events, the device can sustain more than 150% overload for up to 120ms, reducing unnecessary tripping. Built to LPS installation standards, they offer high reliability with a >80,000h lifetime expectancy at 40°C. Installation is streamlined with tool-free push-in terminals and paired input/output connectors, making wiring and daisy-chaining across multiple modules quick and efficient.

Radar sensor R1D/R2D
Whether in rain, snow, strong wind, dust or extreme temperatures: the radar sensor detects objects accurately and reliably under all these conditions. This is ensured both by the robust radar technology and by the various operating modes with which the sensor can be adjusted precisely to the respective application, as well as the high resistance to shocks and vibrations.

Radar sensors for precise measurements
The compact radar sensors impress with their versatility in demanding environments and tight installation situations. With different aperture angles - ±3° (6°), ±7.5° (15°) or a particularly narrow ±1.5° (3°) - they offer maximum focussing for precise positioning tasks and reliable object detection. Thanks to measuring rates of up to 500 Hz, a measuring range of 0.3 m to 40 m and a measuring accuracy of up to ±0.1 mm, they enable a wide range of applications with state-of-the-art radar technology. Thanks to their intuitive operation, the sensors are easy to integrate into existing control concepts. Supported by a PROFINET interface, integrated web server and user-friendly tools, they create transparency in operation and simplify implementation. Whether as a stand-alone solution or in system solutions - the radar sensors combine precision, speed and robustness for the highest requirements.

Radial and axial shaft seals, mechanical seals
The sealing of a moving shaft presents a special situation. In addition to the static sealing on one side of the seal, we have to seal the moving shaft. According to the installation, the sealing can be made radially or axially. The proper seals have to be deployed in this complex requirement. Possible seals range from simple shaft seals until compression loadable PTFE lip seals or mechanical seals.

RadiCal: Niederdruck-Radialventilatoren mit rückwärts gekrümmten Schaufeln
Die RadiCal Radialventilatoren mit rückwärts gekrümmten Schaufeln sind der neue Standard in der Luft- und Klimatechnik. RadiCal ist dabei sowohl die Geräuschminimierung wie auch die weitere Senkung des Energiebedarfs. Denn das RadiCal-Laufrad mit rückwärts gekrümmten Schaufeln besteht aus glasfaserverstärktem Kunststoff. Dies ermöglicht eine strömungstechnisch optimierte Form, die die Geräuschentwicklung glatt halbiert und den Leistungsbedarf deutlich reduziert.

RadiFit EC-Radialventilatoren
Unsere RadiFit Radialventilator-Baureihe mit Spiralgehäuse, doppelseitig saugend und rückwärts gekrümmten Schaufeln ist die neue Systemlösung für zahlreiche Anwendungen in der Industrie und Raumlufttechnik. Durch die hocheffizienten GreenTech EC-Motoren bieten sie einen hohen Wirkungsgrad bei großen Drücken. Zudem sind sie äußerst kompakt, leicht und robust. Das Beste ist aber, der RadiFit passt zu den üblichen Einbauabmessungen für Ventilatoren. Dadurch werden Einbau und Austausch zum Kinderspiel.

Radio controlled safety system UH 6900 - In group mode
The radio controlled safety system UH 6900 of the SAFEMASTER W series, consisting of one group controller and up to 255 group receivers for the safety-related, wireless transmission of emergency stop and control functions, offers more flexibility in safeguarding hazardous areas. High availability, long range and safety are achieved by implementing the latest radio technologies. With the group controller, several receivers can be safely switched off via a unidirectional, safetyrelated radio link. Furthermore, the controller can exchange message, control and status information with a receiving device. The devices enable the connection of up to 3 two-channel safety sensors (emergency stop, LC, safety door, two-hand etc.) and offer simple configuration as well as extensive evaluation and diagnostic options. The main areas of application include mobile applications such as fully automated floor conveyors and driverless transport systems. A simple and cost-effective retrofitting of existing safety systems can also be realized without wiring.

Radio controlled safety system UH 6900 - In pair mode
The safety approved, bidirectional radio controlled safety system UH 6900 from the SAFEMASTER W series, is for the transmission of safety inputs such as E-stop and conventional control functions and offers great flexibility for the protection of hazardous areas. By implementing the latest radio controlled technologies, a high degree of availability, a wide range, and safety is achieved. Two safety zones can easily be connected wirelessly over a considerable distance. The main application areas include applications covering large areas and mobile applications such as fully automated conveyor systems and driverless transport systems. Simple and inexpensive retrofitting of existing safety systems can also be achieved wirelessly with this system. The device allows connection of up to 3 two-channel safety transmitters (E-stop, LC, safety gate, two-hand, etc.), simple configuration, and comprehensive sampling and diagnostic options. With the radio controlled safety system, you will have an automated safety solution that can be integrated wirelessly into various applications. The option to select between three operating modes (complete protected mode, cross mode, protected mode with connectable ratio control) allows the device to be quickly and reliably adapted to your individual application.
