The core component of Kejit gear speed sensor uses magnetoresistance as the detection component, and then uses a new signal processing circuit to reduce noise and improve functions. By comparing with the output waveforms of other types of tooth speed sensors, the error of the measured speed is extremely small and the linear characteristics are very consistent. The sensing objects are magnetic materials or magnetically permeable materials, such as magnetic steel, iron and electrical steel. When the magnetic or permeable material with protrusions (or depressions) on the measured object rotates as the measured object, the sensor outputs a pulse signal related to the rotation frequency to achieve the purpose of speed measurement or displacement detection.

◇因传感器内部有永磁体，安装时应注意避免齿轮与传感器头之间因吸引而产生撞击，而使传感器损坏。
◇若周围电磁干扰大，建议增接屏蔽线，即外壳接地。
