Why Choose the Carlo Gavazzi CB18CLN12PA Capacitive Proximity Sensor?

The Carlo Gavazzi CB18CLN12PA is a versatile capacitive proximity sensor designed for reliable non-contact detection of conductive and non-conductive materials in industrial automation, level monitoring and materials handling applications. Part of the Carlo Gavazzi CB18CLN series, it combines an 18 mm cylindrical housing with adjustable sensitivity, a PNP transistor output and complementary normally open and normally closed switching functions.

The CB18CLN12PA provides a 12 mm rated sensing distance with an adjustable 3–12 mm sensing range. Capacitive sensing technology enables detection of materials including plastics, liquids, powders, grains and granulates as well as conductive targets, making the sensor particularly useful for level indication in tanks, silos, containers and industrial processing equipment.

Designed for non-flush mounting, the CB18CLN12PA operates from a 10–40 V DC supply and provides a PNP complementary NO+NC output. Its plastic cylindrical housing measures 18 × 86 mm, while the integral PVC cable, TRIPLESHIELD™ sensor protection and IP67 enclosure rating provide a dependable sensing solution for demanding industrial machinery.
