Inductive proximity sensor consists of three parts. Oscillator generates an alternating magnetic field. When the magnetic field near the metal target and reach the sensing distance, causing oscillation damping, as well as to stop vibration. Oscillator and stop vibration changes after stage amplifier circuit is processed and converted into a switching signal to trigger the drive control device, so as to achieve the purpose of the non-contact detection of.
