Why Choose the Carlo Gavazzi CB32CLN20SUAX ATEX Capacitive Proximity Sensor?

The Carlo Gavazzi CB32CLN20SUAX is an ATEX-approved capacitive proximity sensor designed for reliable non-contact detection and level monitoring of solid, fluid and granulated materials in potentially explosive dust environments. Part of the Carlo Gavazzi CB32 TRIPLESHIELD™ capacitive sensor series, this Ø32 mm sensor combines adjustable sensing distance, built-in ON-delay functionality and relay switching for dependable industrial automation applications.

The CB32CLN20SUAX provides an adjustable 4–20 mm sensing range and operates from a 100–135 V AC supply. Its SPDT relay output allows direct load switching, while the adjustable ON-delay function can be configured from 1 s to 10 min to suit applications where delayed switching is required.

Designed with a non-flush cylindrical thermoplastic polyester housing, the sensor provides IP67 protection and ATEX approval for suitable explosive dust atmospheres. TRIPLESHIELD™ technology improves immunity against electromagnetic interference, while the capacitive sensing principle enables detection of liquids, powders, grains, granulates and other non-metallic materials.
