Why Choose the Carlo Gavazzi CB32CLN20TC Capacitive Proximity Sensor?
The Carlo Gavazzi CB32CLN20TC is a 32 mm capacitive proximity sensor designed for reliable non-contact detection of solid, liquid and granular materials in industrial level and presence-sensing applications. Its cylindrical smooth-barrel housing and TRIPLESHIELD™ technology provide a robust sensing solution for demanding automation environments.
The CB32CLN20TC uses a non-flush mounting configuration and provides an adjustable sensing distance of 2–20 mm. This adjustable range allows the detection threshold to be matched to different materials and installation conditions, making the sensor suitable for applications involving powders, granulates, liquids, plastics, wood products and other materials.
Operating from 20–250 V AC, the sensor uses a two-wire SCR normally closed (NC) output and is supplied with an integrated 2 m PVC cable. A maximum output current of 500 mA, yellow LED indication and IP67 protection support straightforward integration into industrial machinery and process-control systems.
