Relays with forced guidance are mostly used in control systems for functional safety, i.e. wherever life and limb of people must be protected. With their help, load and monitoring circuits in safety controllers can be linked and monitored in a very simple way. High diagnostic coverage and reliability predestine our relays for applications in machine and plant construction, process technology, medical equipment, elevator controls or railway technology, to name but a few.
Our relay series with two to ten contacts form the basis for a large number of variants. Switching currents from 3mA to 16A are covered as well as relay drives for excitation voltages from 3 VDC to 220 VDC. By using state-of-the-art materials and newly developed contact systems, our relays guarantee above-average system availability. Efficient relay drives and environmentally friendly materials support energy-efficient and environmentally conscious control design. All our products have been approved by the most important testing laboratories and comply with the most important quality and environmental requirements. In addition, we provide the necessary statistical parameters.
Customer-specific relay variants, e.g. according to EN 50155 for railway applications, for the process industry or for elevator construction, are developed together with the customer. Like our standard relays, these relays have short delivery times and are available for years.
The main areas of application for our relays are currently:
- Industrial automation
- Robotics technology
- Mechanical engineering
- Laser and welding technology
- Medical technology
- Elevator technology / lifting systems
- Process technology
- Railway technology
- Combustion plants
- Building control technology
- And wherever people need to be protected or material assets secured.
