The Carlo Gavazzi CB18CLN12TCFT is a robust 18 mm capacitive proximity sensor with a 30-second on-delay, designed for reliable level and material detection in industrial automation, processing and materials handling applications. Part of the Carlo Gavazzi CB18CLN TRIPLESHIELD™ series, it combines adjustable capacitive sensing with a two-wire AC output and normally closed switching function.
The CB18CLN12TCFT provides a 12 mm rated sensing distance with an adjustable 3–12 mm sensing range. Capacitive sensing technology enables detection of both conductive and non-conductive materials, making the sensor suitable for applications involving solids, grains, powders, plastics, liquids and other process materials.
Designed for non-flush mounting, the CB18CLN12TCFT operates from a wide 20–250 V AC supply and uses a two-wire thyristor (SCR) normally closed output. Its integrated 30 s on-delay helps prevent immediate switching from short-duration target changes, while the smooth 18 × 86 mm thermoplastic polyester housing, 2 m PVC cable, TRIPLESHIELD™ protection and IP67 enclosure rating support dependable industrial operation.
Capacitive proximity sensors detect changes in capacitance when a target enters their sensing field. This allows the Carlo Gavazzi CB18CLN12TCFT to detect a wide range of conductive and non-conductive substances, making it particularly useful for level monitoring of solids, grains, powders and other process materials in tanks, silos and containers.
The integrated 30-second on-delay is useful where a target or material must remain present before the output changes state, helping reduce unwanted switching caused by brief material movement or transient detection. Combined with adjustable sensitivity, TRIPLESHIELD™ protection and a wide AC supply range, the CB18CLN12TCFT provides a practical sensing solution for industrial and process automation.
