Working principle

The inductive proximity switch consists of three major components: an oscillator, a switching circuit, and an amplifying output circuit. The oscillator produces an alternating magnetic field. When the metal target approaches this magnetic field and reaches the sensing distance, eddy currents are generated in the metal target, causing the oscillation to decay and even stop. The oscillation and oscillation of the oscillator are processed by the post-amplifier circuit and converted into a switching signal to trigger the drive control device to achieve the non-contact detection purpose.

Product features:

1. Non-contact detection can avoid damage to the sensor itself and the target.

2. No contact output, long service life.

3. Stable testing is possible even in harsh environments with water or oil splashes.

4. The reaction speed is fast.

5. The sensor head is small and flexible to install.
