Accessories for reflex light barriers

Reliable object detection and precise signal feedback

A triple mirror, also known as a cube corner reflector, is the ideal partner for reflex light barriers in industrial applications. Thanks to the special arrangement of three mirror surfaces perpendicular to each other, the triple mirror guarantees the best possible feedback of the light beam regardless of the angle of incidence. This enables error-free detection of objects and increases operational reliability. Especially in combination with a polarization filter, false triggering by highly reflective surfaces is effectively avoided. Triple mirrors are characterized by simple installation, robust construction, and long service life—ideal for optical sensor technology in industrial automation engineering.
