Wholesale optical sensor is a small electronic device, and it is a key component for realizing photoelectric conversion in various photoelectric detection systems. It is mainly a sensor that uses various properties of light to detect the presence or absence of objects and changes in surface states. Wholesale optical sensor have the characteristics of non-contact, fast response and reliable performance, so they are widely used in industrial automation devices and robots.

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