Why Choose the Carlo Gavazzi CB32CLN20RTAX ATEX Capacitive Proximity Sensor?
The Carlo Gavazzi CB32CLN20RTAX is an ATEX-approved capacitive proximity sensor designed for level and material detection in industrial applications involving potentially explosive dust atmospheres. Its cylindrical 32 × 101 mm thermoplastic polyester housing, TRIPLESHIELD™ sensor protection and non-flush installation make it suitable for demanding process and agricultural environments.
The sensor provides an adjustable 4–20 mm sensing distance, allowing sensitivity to be matched to solids, liquids and granular materials. The CB32CLN20RTAX is the version without an integrated time delay and provides an SPDT change-over relay output, enabling suitable loads or control circuits to be switched directly.
Designed for a nominal 230 V AC supply, the sensor operates across 195–255 V AC at 47–53 Hz. It is supplied with an integrated 2 m PVC cable, operates at up to 5 Hz and provides IP67 ingress protection for industrial installations.

ATEX Capacitive Level Detection for Industrial Processes
Capacitive sensing enables the CB32CLN20RTAX to detect changes in dielectric properties as solids, liquids or granular materials approach the sensing area. The adjustable 4–20 mm range allows the detection threshold to be adapted to the target material and installation, making the sensor particularly useful for level monitoring in bins, hoppers and other process vessels.
The CB32CLN20RTAX combines this sensing principle with ATEX approval, TRIPLESHIELD™ protection and an SPDT relay output. Its 230 V AC supply configuration allows it to be incorporated into suitable mains-powered control systems, while the relay output provides a change-over contact for interfacing with appropriate control or signalling circuits.
Typical Applications
- Grain and agricultural material level detection.
- Powder and granular product monitoring.
- Bin and hopper level detection.
- Solid material presence detection.
- Liquid level monitoring.
- Feed and bulk-material handling systems.
- Industrial process equipment.
- Appropriate ATEX explosive-dust applications.
