Operating principle of light barriers and diffuse reflection sensors

Photoelectric sensors function as position sensors, detecting objects by interrupting or reflecting their own light beams.

Light barriers come in three variants: through-beam, retro-reflective, and diffuse reflection sensors. Through-beam sensors transmit a light beam in only one direction, requiring the transmitter and receiver be incorporated in different housings, meaning there is no reflection to the transmitter. With retro-reflective sensors, transmitter and receiver exist in one component, as the transmitted light beam reflects to the receiver by a reflector. By comparison, a diffuse reflection sensors’ transmitter and receiver also exist in one housing, but unlike the retro-reflective sensors, no specific reflector is needed for the reflection. Any object will do; the range of diffuse reflection sensors depends largely on the object surface and the degree of reflection.

There are numerous applications for light barriers and diffuse reflection sensors, such as:

  • Position detection in packaging, conveying and handling technology
  • Object recognition in the wood, paper, cement and automotive industries
  • Positioning in steel processing
  • Detection of vehicles in car wash plants and on gateways
