70156-3987 Photoelectric Sensor Working Principle

The 70156-3987 photoelectric sensor operates based on the reflection or emission of light. Light is emitted from the sensor and reflected off the object being detected. The emitted light then reflects off the object and returns to the sensor. This information is then used to detect the presence or absence of an object. The sensors are typically constructed using two main components - a light source and a receiver.

The light source usually consists of infrared, visible, or ultraviolet LED. In some cases, the light source is combined with a lens that focuses the light onto a surface or object. The lens also acts as a concentrator which increases the intensity and accuracy of the light beam. When the light reflects off the object, it is directed towards the receiver. The receiver typically consists of a photodiode, or more rarely, a photodetector, which is responsible for detecting and collecting the light.

The photoelectric sensor sends out a continuous light beam, and when the light beam is interrupted, or when the reflective light is detected, the receiver sends a signal to the output. The output typically consists of a switch contact or a transistor output, which triggers a connected device such as a motor or an alarm.
