Our reflective light barrier is particularly easy to align thanks to generous installation tolerances. You only need to install one electrical device plus a reflector. Large reflectors ensure long ranges. The light barriers detect objects regardless of surface, color and material. A polarizing filter also makes them suitable for detecting shiny objects. Optoelectronic sensor, light transmitter=LED, connection type=plug connector, switching output=PNP normally open/normally closed (NO/NC), max. range=5 m
