WebWhat is a Photoelectric Sensor? A photoelectric sensor emits a light beam (visible or infrared) from its light-emitting element. A reflective-type photoelectric sensor is used to detect the light beam reflected from the target. A thrubeam type sensor is used to measure the change in light quantity caused by the target crossing the optical axis. WebA photoelectric smoke detector typically has an electric light source and a light sensor inside. Photoelectric smoke detectors are capable of detecting the way smoke impacts light, which is especially useful given that visibility is limited in a smoke-filled room. Depending on the type, the mechanism of smoke detection differs.

"A photoelectric sensor is a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are largely used in industrial manufacturing. There are three different useful types: opposed (through-beam), retro-reflective, and proximity-sensing (diffused).
