Capacitive proximity switches are usually measured by one plate of the capacitor, and the other plate is the shell of the switch. This enclosure is usually grounded or connected to the enclosure of the device during the measurement. When an object moves to the proximity switch, regardless of whether it is a conductor or not, due to its proximity, the dielectric constant of the capacitor is always changed, so that the capacitance changes and the state of the circuit connected to the measuring head also occurs. Change, which can control the switch on or off. The objects detected by this proximity switch are not limited to conductors, liquids or powders that can be insulated.
