Photoelectric sensors & photoelectric switches are composed of a light projector and a light receiver. The light projector converts the input current into an optical signal and emits infrared light. Since the detection object blocks or reflects the light beam, the light received by the light receiver will have changes, thereby photoelectric sensor can detect the object existing or not. The detection object is not only metal, but also any transparent or opaque object that can reflects light or blocks light, such as glass, rubber, wood, liquid, gas, etc. Because it is a non-contact detection, photoelectric sensors won't damage the detection objects, and be affected by them.
