YUMO Cylinder Proximity Sensors CM18-3008NA Capacitance Non-flush Sensor Switch

A capacitive sensor is an electronic device that can detect solid or liquid targets without physical contact. To detect these targets, capacitive sensors emit an electrical field from the sensing end of the sensor. Any target that can disrupt this electrical field can be detected by a capacitive sensor.

Cylinder Proximity Sensors CM18-3008NA Capacitance Non-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.
