Capacitive Sensors

Capacitive Proximity Switches are used for the non-contact detection of any objects. In contrast to inductive switches, which only detect metallic objects, capacitive sensors can also detect non-metallic materials. Typical application are in the wood, paper, glass, plastic, food and chemical industries. Capacitive Sensors for example monitor that the contents of a cardboard box are complete or check the presence of the non-metallic caps. Another application is to monitor the conveying of sheets of glass on a roller conveyor.
