Omron Retro-reflective Sensor With Model Number E3Z-D82 2M detect objects, changes in surface conditions, and other items through a variety of optical properties. A Photoelectric Sensor consists primarily of an Emitter for emitting light and a Receiver for receiving light. The photoelectric effect occurs when electrons are released after light is shone onto a metal. Photoelectric sensors use light and optics to detect object presence or distance. They provide an output based on object detection or distance criteria.
