The capacitor is formed by two disks, charged with opposite electrical
load, mounted on the sensing face to project the electric field to
sensor´s outside, thus creating a capacitor which has the air as the
dielectric. As the sensor oscillator is controlled by the front capacitor,
when some material is approached, their capacitance also changes,
bringing out a change in the oscillator circuit. This variation is converted
into a continuous signal, which compared with a standard value, pass
to activate on the output stage.
2.2 - Sensing Face:
This is the surface where the electrical field emerges.

5 - Special Cares:
The sensing distances in the capacitive sensors are specified to the
metallic activator made of steel SAE 1020 square grounded and with
the side equal the 3 times of the sensing distance for the not Flush
models (the great majority) and in some few cases of Flush capacitive
sensors uses the square side as the same size of the sensor diameter.
The sensitivity adjuster is mainly to reduce the activator influence,
caused by materials near of the sensor sensitivity area, decreasing its
sensing distance.
