Capacitor proximity sensors:

A) are actuated by both conductive and nonconductive materials.
B) are actuated by conductive materials only.
C) produce an electromagnetic field.
D) have a long sensing range.

Capacitor Proximity Sensors

Sensors that use the capacitance change principle to detect the presence or absence of objects, often used in material handling and level control applications.

Conductive Materials

Materials that permit the flow of electric current, often used in electrical and electronic applications for wiring and components.

Electromagnetic Field

A physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field.
