Four Wires Capacitance Proximity Sensors CM30-3010PC Flush Sensor Switch
The inductionsurface of capacitance sensor is composed of two coaxial mental electctrodes,which form a capacitor and connected on RC oscillation circuit, just like an open capacitor electrode.
When connecting to power supply ,RC osillator does not work. When an object is close to capacitor electrode,the capacitor capacity will increase,and the sillator will vibrate. Through the treatment of behind stage circuit, both signals of stop ocillatian and oscillation will be converted to switch signs for checking the existence of abject.this distance can be obtained, but to nonmetal object,the action distance is determined by material dielectric constant, the more dielectric constant,the more ac tion distance will be obtained.
