Photoelectric Proximity Sensors Operating Principles
Photoelectric sensors use light sensitive elements to detect objects and are made up of an emitter (light source) and a receiver. We offer three types of photoelectric sensors are available.
Photoelectric sensor types:
Direct Reflection (Diffused) - emitter and receiver are housed together and use the light reflected directly off the object for detection.

Reflection with Reflector (Retro-reflective) - emitter and receiver are housed together and require a reflector. An object is detected when it interrupts the light beam between the sensor and reflector.

Thru Beam - emitter and receiver are housed separately and detect an object when it interrupts the light beam between the emitter and receiver.
