What is a photoelectric sensor?

The photoelectric sensor is a sensor that uses a photoelectric element as the detection element. It first converts the measured change into a change in the optical signal, and then further converts the optical signal into an electrical signal with the help of photoelectric elements. The photoelectric sensor is generally composed of three parts: a light source, an optical path and a photoelectric element. The photoelectric detection method has the advantages of high accuracy, fast response, non-contact, etc., and there are many measurable parameters, the structure of the sensor is simple, and the form is flexible and diverse. Therefore, the photoelectric sensor It is widely used in detection and control. The photoelectric sensor is the key element to realize photoelectric conversion in various photoelectric detection systems. It is a device that converts light signals (infrared, visible and ultraviolet radiation) into electrical signals.
