Contrinex introduces its line of capacitive proximity switches for monitoring the levels of liquids, pastes and bulk material in machines, installations and vehicles even through non-metallic dividing walls. These switches are suitable as limit switches, contact-free position switches, for monitoring and positioning, as pulse generators for counting purposes, and for distance and speed measurement. They are enclosed in PPO or PTFE synthetic housings and 304 stainless-steel or nickel-plated brass metal housings and potted in epoxy resin. They are virtually insensitive to dirt and shock, and they feature IP 67 degree of protection. Equipped with a 20-turn potentiometer, these switches allow for adjustment of the operating distance which can be either longer than or shorter than the rated operating distance.
