Product Description
CM20 ABS resin IP54 NPN PNP 12V capacitiance proximity sensor with CE
Working principleof capacitance proximity switch
Capacitance proximity switch
* The induction surface of capacitance sensor is composed of two coaxial mental electctrodes, which from a capacitor and connected on RC oscillation circuit, just like an open capacitor electrode.
* When connecting to power supply, RC oscillator does not work. When an object is clos eto capacitor
electrode, the capacitor capacity will increase, and the oscillator will vibrate. Through the treatment of behind stage circuit, both signals of stop oscillation and oscillation will be converted to switch signs for checking the existence of object. this distance can be obtained, but to nonmetal object, the action distance is d etermined by material dielectric constant, the more dielectric constant, the more action distance will be obtained.
