Capacitive proximity sensors CQ

  • 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

Description

Overview

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.
