Capacitive Proximity Switches

Manufacturer: Contrinex
Category: Capacitive Proximity Switches

Robust and extremely versatile, Contrinex capacitive sensors detect position or presence of conductive and non-conductive materials, including liquids, pastes and bulk solids. Capacitive technology permits detection of targets through thin non-metallic barriers, ideal for controlling packaging and filling processes. Capacitive sensors generate electrostatic fields that change as a target approaches.

The target material increases the sensor capacitance, triggering an internal oscillator at the pre-set sensing distance. Resin-encased with plastic or metal housings, capacitive sensors resist impact, vibration and contamination, allowing contact or non-contact sensing. Engineers specify capacitive sensors as limit switches and non-contact

Capacitive Basic

Contrinex Basic range capacitive sensors deliver not only a reliable solution for all kinds of level sensing tasks but also for object detection and positioning of virtually all materials.

Capacitive High Performance

Contrinex High Performance capacitive sensors deliver a solution even for the most difficult sensing tasks. All models come with an extended medium optimized operating distance for an improved switching behavior.


All capacitive sensors from Contrinex come with a potentiometer to ensure an easy setup. They are available in cylindrical housings sized from M12 to M30 and cubic forms with sensing distances of up to 70mm.
