Product Description
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.
Some photoelectric switches have two different operational types: Light operate(light-on) and dark operate(dark-on). Light operate photoelectric switches become operational when the receiver "receives" the transmitter signal. Dark operate photoelectric switches become operational when the receiver "does not receive" the transmitter signal.
