Why Choose the Carlo Gavazzi CB32CLN20SVAX Capacitive Proximity Sensor?
The Carlo Gavazzi CB32CLN20SVAX is an ATEX-approved capacitive proximity and level sensor designed for reliable detection of solids, liquids, powders and granulated materials in demanding industrial applications. As part of the Carlo Gavazzi CB32 TRIPLESHIELD™ sensor range, it combines adjustable capacitive sensing with an integrated OFF-delay and SPDT relay output for flexible process and level-control applications.
The CB32CLN20SVAX provides an adjustable sensing distance of 4–20 mm with a rated sensing distance of 20 mm. Its non-flush, smooth cylindrical 32 mm diameter housing and capacitive sensing principle allow it to detect conductive and non-conductive materials, making it particularly suitable for monitoring grain, powders, granulates, liquids and other bulk materials.
Designed for a nominal 115 V AC supply with a rated supply range of 100–135 V AC, the CB32CLN20SVAX incorporates an SPDT change-over relay output and adjustable 1 s to 10 min OFF-delay. A factory-fitted 2 m PVC cable, TRIPLESHIELD™ construction, IP67 enclosure and ATEX approval provide a robust sensing solution for industrial and potentially explosive dusty environments.

Reliable Level Detection for Industrial Applications
Capacitive proximity sensors detect changes in capacitance when a target enters their sensing field, enabling reliable detection of both conductive and non-conductive materials. This makes the Carlo Gavazzi CB32CLN20SVAX particularly useful for monitoring grain, powders, granulates, liquids and other materials where conventional inductive proximity sensing is unsuitable.
The integrated adjustable OFF-delay keeps the relay output in its switched condition for the configured period after the target is no longer detected, providing useful control functionality for filling, emptying and material-handling processes. Combined with its SPDT relay output, TRIPLESHIELD™ technology, ATEX approval and robust IP67 housing, the CB32CLN20SVAX is well suited to demanding industrial and bulk-material level-control systems.
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 emptying machinery.
- Conveyor and material-handling equipment.
- Hazardous dusty industrial environments requiring ATEX-approved sensing.
