Need safe position switches? You've come to exactly the right place. Because our position switches and safety switches detect movement sequences and states in the field – safely. This makes them the first link in the safety chain. After detecting, they forward the signals safely to safe evaluation units such as safety relays, software-parameterizable safety relays, or fail-safe controllers. The switches offer the right solution depending on the hazard.
With a large number of position switches, personnel protection is ensured by positive opening of the NC contacts. The 3SE5 position switches with positive opening enable safety category SIL 1 / PL c.
Safety category SIL 2 / PL d can be achieved with just one safety switch.
Higher safety categories such as SIL 3 / PL e can be achieved by using combinations of switches. Depending on the requirements of the application, different switches can be combined.
