The Photo electric sensor is used to detect metallic and non-metallic targets. Photoelectric sensors use light sensitive rudiments to sense objects and are made up of a light source emitter and a receiver.
Some of the photo electric sensor types that we deal with include:
Photoelectric Diffuse- In this type the emitter or receiver are held together and uses the light reflection directly to detect objects.
Retro Reflective or Photoelectric Reflex- Here a high level of reflected light allows reflex sensors to detect objects.
Photoelectric thru beam- It comprises of an emitter and receiver that are held separately and sense the objects when it intrudes the light between the emitter and receiver.
