Product Description

Photoelectric Switch (E3JK Series)

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.
