Proximity Switches

Photoelectrical - Optical - Infrared Proximity Switch / System

Photoelectrical, opticl, infrared proximity switch Beam of invisible pulsed modulated infra-red light is produced by emitter. This beam is sensed by receiver at another end (in through beam version) or reflected by object and received by received placed near emitter (in diffuse version). When this beam is interrupted by object, the receiver signal gets changed and signal is produced.

Optical proximity switches are used where higher sensing distance is required with non contact operation.

The object can be sensed by three methods

  1. Diffused Reflective Type
  2. Retro Reflective Type
  3. Through Beam Type
