Pr18-5DN autonics 18mm proximity sensor, 5 mm sensing, NPN NO

This inductive proximity sensor generates an electromagnetic field to sense metal objects. It features built-in sensitivity volume and provides no-touch object detection. Inductive sensors use a magnetic field to detect objects. Capacitive sensors also use an electric field. In order to be sensed by an inductive sensor, an object must be conductive.

This limits suitable targets to metal objects (for the most part). In order to be sensed by a capacitive sensor, the target doesnt need to be conductive. A capacitive sensor will react to an object acting as a dielectric material as well as a conductive object. This makes metal and non-metal objects suitable targets.
