Description

CM18-2008A controllable silicon capacitive proximity switch

The induction surface of capacitance sensor is composed of two coaxial mental electrodes, 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 close to 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 determined by material dielectric constant, the more dielectric constant, the more action distance will be obtained.
