Balluff’s retroreflective sensor is especially easy to align thanks to generous mounting tolerances. You only need to mount one electrical device plus a reflector. Large reflectors guarantee high ranges. The light barriers detect objects regardless of their surface, colour and material. A pole filter makes them suitable for detecting shiny objects as well.
