Inductive proximity sensors target ferrous metals while Capacitive sensors can sense any material from solids to liquids.
A shielded inductive proximity sensor can be embedded flush in its mounting material without affecting
the sensor’s field of detection. The unshielded inductive proximity sensor has the advantage of longer sensing distances. With
proximities available in NPN or PNP models it easily finds applications in motion and speed detection, robotics and conveyors, liquid
level control, package inspection, etc.
