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. Thanks to a polarizing filter, they are also suitable for detecting shiny objects. Optoelectronic sensor, transparency detection, light transmitter=LED, connection type=plug connector, switching output=NPN normally open (NO),NPN normally closed (NC) pins 4-2, range max.=1.7 m
