Describe the operation of a capacitive prox switch.

What will be an ideal response?


The capacitive prox works just the opposite of the inductive prox in that the
oscillation of the circuit begins when the item sensed enters the electrostatic field
and it dies off when no object is present. The capacitive prox has an adjustment
on the switch that allows the user to vary the electrostatic field and change the
distance it interacts with objects.
