Mounting a light emitter and a receiver face to face on either side of a slot is a trough optoelectronic. The illuminator emits infrared or visible light, and the light receiver receives light in an unobstructed condition.

The high-pressure proximity sensor is widely used in life. It is mainly used in the fields of booster cylinder, supercharger, gas-liquid booster cylinder, gas-liquid booster, press, compressor, air-conditioning

The frequency response characteristics of the sensor determine the range of frequencies being measured and must remain undistorted within the permissible frequency range. In fact, the response of the

The magnetic core inside the proximity switch passes through the metal to change the internal oscillation circuit and output a signal. Suitable for detecting metal objects with relatively close distances.

According to its basic sensing function, it can be divided into thermal sensor, photosensitive element, gas sensor, force sensor, magnetosensitive sensor, humidity sensor, sound sensor, radiation sensor,

Most of the thermal resistances are made of pure metal materials. Currently, platinum and copper are the most widely used. In addition, thermal resistances such as nickel, manganese and tantalum have been used.
