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

Types of Photoelectric Proximity Switches

The object can be sensed by three methods

A) Diffused Reflective Type :

This is a fixed focused type of switch. Transmitter and receiver enclosed in one housing. Transmitted beam strikes on the object (when the object enters the sensing range ) and gets reflected by object surface. Receiver detects these rays and output signal is produced.

B) Retro Reflective Type :

Transmitter and receiver are housed in single housing and aligned with the reflector. The beam reflected by the reflector gets back to the receiver. Object breaking the light beam causes a change at the receiver. This change initiates an output signal.

C) Through Beam Type :

Transmitter and receiver are enclosed in two separate housings. When they are aligned light beam travels from transmitter to receiver. Object breaking the light beam causes a change in the receiver. This change is detected and output signal is produced to drive external relay
