The Safety light-beam sensors safely monitor access points over large distances. Their standardized and compact housing allows fast commissioning. Performing diagnostics is also easy. The safe human-material differentiation assists the material flow, which in turn ensures fewer downtimes and smooth processes – even in harsh ambient conditions.

The WSU/WEU26-3 photoelectric safety switch is used for access protection for hazardous areas on machines or systems. It has a self-testing sender and receiver. The devices are firmly mounted in the access area with the necessary safety distance from the nearest hazardous point, and send a deactivation signal to the machine or system if the light beam is interrupted.
