You may have heard of both inductive and capacitive proximity sensors, what is the difference?

Inductive proximity sensors are generally used to sense metal while capacitive proximity sensors will sense metal as well as nonmetallic materials including paper, glass, liquids and cloth.

capacitive proximity sensorsInductive proximity sensors use an electromagnetic field while capacitive proximity sensors produce an electrostatic field.

A common application for capacitive proximity sensors is level detection through a barrier.
