The sensor overcomes many shortcomings of the traditional sensor. It has high reliability, no external interference and high detection sensitivity (it can accurately monitor no less than 0.02mm fiber). It has irreplaceable advantages in anti light interference, anti sound interference, anti electromagnetic wave interference and anti strong vibration, At the same time, it can adapt to the environment temperature and humidity in a wide range (- 25 ℃ ~ 95 ℃), adapt to a wide range of host speed, long service life, and normal power consumption is less than 0.1W, which provides an exact guarantee for the reliability and adaptability of the whole machine. The response time of yarn breaking can be set in advance according to the requirements of the host plant and users, and can also be customized according to the requirements of the user in the interface, appearance, installation position, etc.

　　After user's test and application, the technical indexes of the sensor are higher than those of the similar products at home and abroad. Through the long-term supporting use of Yifang textile machinery factory and other customers, it has won the praise of the majority of users.
