The CQ capacitive proximity sensors offer a sensing range (Sn) from 1 mm to 10 mm and are designed for non-flush installation. They use DC 3-wire electrical wiring and come with a cable featuring an M8 male connector with 4 pins. The switching output can be configured as either normally closed (NC) or normally open (NO). 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. The CQ sensors feature rectangular housings that are suitable for all manner of installation conditions.

Rectangular housing
Detects powders, granulates, liquids and solids
Extremely high electromagnetic compatibility
Electric version: DC, 4 cables
Supply voltage: 10 V ... 36 V DC
Short-circuit protection (pulsed)

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

Factory automation
Consumer care: Level measurement on the adhesive container
Health care manufacturing: Hazardous point protection and leak monitoring
Handling and assembly technology: Detection on the rotary magazine table
Handling and assembly technolo
