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=laser, connection type=cable, switching output=PNP normally open (NO), PNP normally closed (NC) pins 4-2, max. range=16 m
