      The principle of linear proximity sensor is that the linear device which belongs to metal induction will produce alternating magnetic field on the sensor surface when the power supply is switched on. When the metal object approaches the sensing surface, eddy current is generated in the metal and the oscillation is absorbed. The energy of the oscillator linearly attenuates the output amplitude of the oscillator, and then performs the non-contact detection of the object based on the attenuation variation.
      The proximity sensor has no sliding contact and is not affected by non-metallic factors such as dust during operation. Long life power consumption can be used in various harsh conditions.
