Capacitive proximity sensors
CQ

Reliable capacitive proximity sensors enclosed in a rectangular housing

Your Benefits

Non-contact level measurement, even through container or tank walls, which eliminates drilling holes and thus reduces installation time
Durable housing withstands harsh industrial applications, reducing maintenance costs
Quick and easy adjustment of the switching point - via pushbutton, remote teach for the CQ28 and via potentiometer for CQ35 - saves time
Simple and safe detection alternative to photoelectric and inductive sensors in applications such as detecting product in a sealed box, container or tank

Overview

Reliable capacitive proximity sensors enclosed in a rectangular housing

Capacitive proximity sensors can detect all types of material: powder-based, granulated, liquid, and solid – even through plastic walls. SICK’s capacitive proximity sensors also feature high electromagnetic compatibility (EMC), which prevents incorrect switching.

CQ sensors feature rectangular housings that are suitable for all manner of installation conditions.
