- High noise immunity - Sensing range adjustable by means of potentiometer or teach button - Plastic or metal housings for different applications - Sensors for position and level detection - Accessories for mounting on tanks or sight glasses Capacitive sensors are used for the non-contact detection of any objects. In contrast to inductive sensors, which only detect metallic objects, capacitive sensors can also detect non-metallic materials. Typical applications are in the wood, paper, glass, plastic, food, chemical and semiconductor industries.
