 Inductive proximity switches from high-frequency oscillation, detection, amplification, trigger and output circuit. Oscillator sensor detection surface produce an alternating electromagnetic field, when the proximity sensor detects the metal object surface, the eddy current generated in the metal absorbs the energy of the oscillator, as well as weaken the oscillation stop vibration. Oscillator and stop vibration of these two states, converts electrical signals into binary switching signal shaping amplifier, the power amplifier output. Capacitive proximity switches from high-frequency oscillator and amplifier, etc., by the Inter-detection sensors and the earth surface to form a capacitor, the work involved in the oscillation circuit Shenzhen proximity switch dealers starting state to stop vibration. When the sensors detect objects close to the face, the circuit capacitance changes, the high frequency oscillator. Oscillation and these two kinds of state to stop vibration into an electrical signal by the amplifier into a binary switching signal. Capacitive proximity switch sensors are electrodes for detecting end of electrostatic induction way Guangzhou proximity switch price, plus a voltage of the electric field generated by the electrodes in Dongguan proximity switches wholesale, once the object exists, the object would be generated by electrostatic induction polarization. The closer the electrode body proximity switch, the more electric charge, since the electrode of the electrostatic capacitance C = q / U, so the charge q to increase the capacitance, C will increase, i this, is the size of the sample, the thickness, the relative permittivity power factor, the more wide-range electrostatic induction, which can detect objects farther away. Inductive proximity switches eddy current sensor is a perception of objects pass amplification, shaping circuit and output circuit, sensor perception - whether the actinides. The purpose of § Proximity switch sensors utilize a displacement sensor switch signal. Thus, in general proximity switch sensor by the high frequency oscillator circuit, detector 7 detects the electrical coil, so that when a group of objects close to the oscillation circuit of the detection coil. I belong to a titanium material to make pie soup weaken until it stops vibrating. This oscillation and stop vibration detection circuit into two states by switching signal output.
