Retro-Reflex Sensors

In retro-reflex sensors, the transmitter and receiver are located in a single housing.
They operate using red light, laser light and a reflector. The output switches if the light beam between the sensor and reflector is interrupted. Even shiny, chromed or reflective surfaces can be reliably detected thanks to the integrated polarization filter.

Application examples:

  • Object recognition at great distances
  • Presence control on conveyor belts
  • Monitoring of stacking heights
  • Mounting and supply control
  • Gap control
