Why Choose the Carlo Gavazzi CB32CLN20QUAX5M Capacitive Proximity Sensor?
The Carlo Gavazzi CB32CLN20QUAX5M is an ATEX-approved capacitive proximity and level sensor designed for reliable detection of solids, liquids and granulated materials in demanding industrial applications. As part of the Carlo Gavazzi CB32 TRIPLESHIELD™ sensor range, it combines adjustable capacitive detection with an integrated ON-delay timer and relay output for direct and flexible control.
The sensor provides an adjustable sensing distance of 4–20 mm and features a non-flush, smooth cylindrical 32 mm diameter housing. Its capacitive sensing principle allows it to detect a wide range of conductive and non-conductive materials, making it particularly suitable for level monitoring of powders, grain, granulates and liquids.
Designed for a nominal 24 V AC/DC supply, the CB32CLN20QUAX5M incorporates an SPDT change-over relay output and adjustable ON-delay from 1 s to 10 min. A factory-fitted 5 m PVC cable, TRIPLESHIELD™ sensor protection, IP67 enclosure and ATEX approval provide a robust sensing solution for industrial and potentially explosive dusty environments.

Reliable Level Detection in Industrial Environments
Capacitive sensors detect changes in capacitance when a material enters their sensing field, enabling reliable detection of both conductive and non-conductive substances. This makes the Carlo Gavazzi CB32CLN20QUAX5M particularly useful for monitoring levels of grain, powders, granulated materials and liquids where conventional inductive sensing technology is unsuitable.
The integrated adjustable ON-delay allows the output to switch only after a target has remained detected for the configured period, helping prevent unwanted switching caused by brief material movements or transient conditions. Combined with its SPDT relay output, TRIPLESHIELD™ protection and ATEX-approved construction, the sensor is well suited to demanding level-control and industrial automation installations.
Typical Applications
- Grain and agricultural material level detection.
- Powder and granulate monitoring in silos and hoppers.
- Liquid level detection and process control.
- Feed, seed and bulk-material handling systems.
- Industrial filling and packaging machinery.
- Conveyor and material-handling equipment.
- ATEX-rated dusty industrial environments.
