Why Choose the Carlo Gavazzi CB32CLN20TO Capacitive Proximity Sensor?
The Carlo Gavazzi CB32CLN20TO is a 32 mm capacitive proximity sensor designed for non-contact detection of solid, liquid and granular materials in industrial level and presence-sensing applications. Part of the Carlo Gavazzi CB32CLN TRIPLESHIELD™ range, it combines an extended adjustable sensing distance with a two-wire AC solid-state output.
The CB32CLN20TO uses a non-flush mounting configuration and provides an adjustable sensing distance of 2–20 mm. Its capacitive sensing principle enables detection of metallic and non-metallic materials, making it particularly suitable for level monitoring of grain, feed, powders, liquids, plastics and other process materials.
Operating from 20–250 V AC, the sensor provides a two-wire SCR normally open (NO) output with a maximum operating current of 500 mA. Its smooth cylindrical Ø32 × 101 mm thermoplastic polyester housing, integrated 2 m PVC cable, 10 Hz operating frequency and IP67 protection provide a robust solution for industrial automation and level-detection systems.

Reliable Two-Wire AC Capacitive Detection
Capacitive proximity sensors respond to changes in capacitance as material enters the sensing field, allowing the CB32CLN20TO to detect both metallic and non-metallic targets without physical contact. Its adjustable 2–20 mm sensing distance allows sensitivity to be adapted for materials such as grain, feed, powders, liquids, plastics, wood products and other solids or granulates.
The CB32CLN20TO combines this versatile sensing principle with a two-wire AC SCR normally open output and Carlo Gavazzi TRIPLESHIELD™ technology. The sensor is particularly suited to level detection in tanks, silos, bins and containers, while its integrated PVC cable and wide AC operating-voltage range simplify integration into suitable industrial control systems.
Typical Applications
- Grain and agricultural material level detection.
- Powder and granular material sensing.
- Tank, silo, bin and container level monitoring.
- Feed and bulk-material detection.
- Plastic and rubber processing machinery.
- Wood, sawdust and paper-product detection.
- Conveyor and material handling equipment.
- Industrial process and production automation.
