The operating principle of capacitive proximity sensors is similar to that of inductive sensors. An electromagnetic field is generated by a capacitor located on the main side of the sensor. A nearby part changes the intensity and frequency of oscillations. Unlike inductive sensors, capacitive sensors do not only detect metal parts, but parts of all shapes and materials (solid, liquid, viscous, powdery, etc.).
The main characteristics of capacitive sensors are:
