Photoelectric Retro-Reflective Sensor

A photoelectric retro-reflective sensor is a type of sensor that uses light to detect the presence or absence of an object. It works by emitting a beam of light and then detecting the reflected light from the object. The sensor has two main components: a light source (LED) and a photodetector.

The LED emits a beam of light that is directed towards a retro-reflective target. A retro-reflective target is a surface that reflects light back to its source. When an object enters the path of the light beam, it interrupts the reflection of light back to the sensor. This interruption is detected by the photodetector, which triggers a signal.
