After supplying power to the switch, the oscillator in the high-frequency oscillation circuit generates an alternating electromagnetic field on the detection surface of the switch. When a metal approaches the detection surface of the switch, the eddy currents inside the metal absorb the energy of the alternating electromagnetic field in the oscillator, causing it to weaken or stop oscillating. The two states of energy change in the oscillator are converted into a level signal by the detection circuit. The level signal is amplified by the amplification circuit and triggered by the trigger circuit to output the transistor circuit, generating a switching signal. So as to detect the presence of metals and achieve the purpose of detecting metals. a. Basic parameters 1. Product model: LJ12A3-4-Z/BX 2. Working voltage: 6-36VDC 3. Detection distance: 0-4mm 4.
