Our current product catalog
Capacitive sensors or capacitive proximity switches are available in different designs and with different housing materials.
The principle of operation is as follows:
The non-contact capacitive sensor converts a quantity that is interesting from a production point of view (distance or level) into an analog or digital signal that can be further processed. The function is based on a change in the electric field in the vicinity of its active zone.
The basic structure of the sensor consists of an RC oscillator as a pick-up, a demodulator and an output stage (PNP, NPN, complementary, normally closed, normally open or analog as voltage or current output)
The approach of metals or non-metals into the active zone of the capacitive sensor causes a change in capacitance, whereby the RC oscillator begins to oscillate. This causes the trigger stage connected downstream of the oscillator to tilt and the switching amplifier changes its output state or its output current or its output voltage.
