Capacitive proximity switches from Contrinex monitor levels of liquids, pastes, and bulk material in machines and more, even through non-metallic dividing walls.

Old Saybrook, CT —New line of capacitive proximity switches from Contrinex is intended for monitoring the levels of liquids, pastes, and bulk materials in machines, installations, and vehicles, even through non-metallic dividing walls. Devices are also suitable for use as limit switches, contact-free position switches, for monitoring and position, as pulse generators for counting, distance, and speed measurement.

Switches are enclosed in PPO or PTFE synthetic housings and 304 stainless-steel or nickel-plated brass metal housings and potted in epoxy resin. The devices are virtually insensitive to dirt and shock and offer 1067 protection. They come as 4-wire switches in sizes M12, M18, and M30 (PNP or NPN with changeover outputs), 2-wire switches (ac/dc, NO) in sizes M18 and M30, embeddable or non-embeddable versions. Connection is made by a standard 2 m cable or S12 connector. Non-standard cable lengths and types are available on request.

Switches are equipped with a 20-turn potentiometer to allow for adjustment of the operating distance, which can be longer or shorter than the rated operating distance. All production is ISO 9001:2000 certified.
