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). Web•With a Through-beam Sensor, the lens diameter determines the size of the smallest object that can be detected. •With a Through-beam Sensor, a small object can be more easily detected midway between the Emitter and the Receiver that it can be off center between the Emitter and Receiver.

Web1. Through-beam Sensors Sensing Method. The Emitter and Receiver are installed opposite each other to enable the light from the Emitter to enter the Receiver. When a sensing object passing between the Emitter and Receiver interrupts the emitted light, it reduces the … 1. Proximity Sensors detect an object without touching it, and they therefore do … WebA beam of light is emitted from the light emitting element and is received by the light receiving element.
