Our reflective light barrier is particularly easy to align thanks to generous installation tolerances. You only need to install an 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.
