Retroflective Sensors

Retroreflective photoelectric sensors have an emitter and a receiver in the same housing. Retroreflective sensors require a quality reflector to reflect the light beam back to the sensors receiver. The output is triggered when the target object breaks or interrupts the light beam.

Advantages of retroreflective sensors include:

  • Longer sensing ranges than diffuse mode
  • More cost effective than thru-beam
  • Easy alignment especially when using red light or laser
  • Polarized versions are available to detect shiny objects
  • Versions for transparent detection
