 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 that two states Guangzhou proximity switch price, converted into an electrical signal into a binary switching signal shaping amplifier, the power amplifier output. Capacitive proximity switches from high-frequency oscillator and amplifier proximity switches and other components Dongguan wholesale, by the inter-sensor detection surface of the earth to form a capacitor oscillator circuit involved in the work, the initial 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 switches: capacitive proximity switches are covered by a position sensor has a proximity switch output, capacitive proximity switches measuring head is usually composed of a plate of the capacitor, and the other plate is itself an object, when the object When moved to the proximity switch, objects and changes in the dielectric constant of the proximity switch proximity switch, making the circuit state and the probe is connected also will be changed, which can control the proximity switch on and off. Such proximity switches detect objects, is not limited to metallic conductors, may also be an insulating liquid or powdered objects Zhongshan proximity switch sales, upon detection of a low dielectric constant ε of the object, capacitive proximity switches can be adjusted more clockwise turn potentiometer (located near the rear of switch) to increase the sensor sensitivity, general adjustment potentiometer allows capacitive proximity switch in position 0.7-0.8Sn action Guangzhou proximity switch sales | News fly Electronics (certified) | proximity switches from Dongguan Flying City Electronics Limited.
