Our reflection light barrier is particularly easy to align thanks to generous installation tolerances. You only 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.
