Capacitive Proximity Sensors Capacitive proximity sensors work on the principle of the capacitor. The main components of the sensor are the plate, oscillator, threshold detector and an output circuit.

Comparison of Capacitive with Induction Sensors. Capacitive sensing involves charging up plates, so it is somewhat slower than inductive: 10 to 50 Hz, with a sensing distance from 3 to 60 mm.

The sensor tip is a small capacitor coupled to the live conductor. As a result, the sensing circuit in the tester detects voltage and signals to you via a lamp, tone, ticking noise, or buzzer that ...
