A photoelectric switch is a device used to detect the distance, absence, or presence of an object
by using a light transmitter, often infrared, and a photoelectric receiver. They are used extensively
in machinery, textile, metallurgy, tobacco, railway, war industry and so on. There are three different
functional types: through beam (opposed), retroreflective, and diffused type ( proximity sensing) .
A through beam (opposed) arrangement consists of a receiver located within the line-of-sight of the transmitter. In this mode, an object is detected when the light beam is blocked from
getting to the receiver from the transmitter.
A retroreflective arrangement places the transmitter and receiver at the same location and uses
a reflector to bounce the light beam back from the transmitter to the receiver. An object is sensed
when the beam is interrupted and fails to reach the receiver.
A diffused (proximity sensing) arrangement is one in which the transmitted radiation must reflect off
the object in order to reach the receiver. In this mode, an object is detected when the receiver sees
the transmitted source rather than when it fails to see it.
