Photoelectric Sensors

Working Principles

A sensor is made up of an irradiating element, a particular type of light (usually infrared, red or green) and an element photosensitive to the irradiated light. The presence or absence of light on the photosensitive element is used as a signal producing a change in the output of the sensor. Thanks to the qualities of transmission and propagation of the light, different types of sensor can be used.
