Why Choose the Carlo Gavazzi CA18CLL12BP Capacitive Proximity Sensor?

The Carlo Gavazzi CA18CLL12BP is a high-performance M18 capacitive proximity and level sensor designed for reliable non-contact detection of liquids, dry bulk materials and other conductive or non-conductive targets. Part of the Carlo Gavazzi CA18 TRIPLESHIELD™ series, it combines single-step teach-in adjustment with automatic NPN/PNP load detection for flexible integration into industrial automation and process-control systems.

The CA18CLL12BP provides an adjustable 0.5–12 mm sensing range, allowing the detection point to be configured to suit the target material and installation. Its three-wire DC output automatically detects an NPN or PNP load, while normally open or normally closed switching can be selected through the teach-in function. Humidity compensation helps maintain stable operation in applications where environmental conditions may affect conventional capacitive sensors.

Operating from a 10–40 V DC supply, the sensor features a flush-mountable M18 thermoplastic polyester housing and a 2 m PVC cable. TRIPLESHIELD™ protection, short-circuit protection, reverse-polarity protection, transient protection and an IP68 enclosure rating make the CA18CLL12BP particularly suitable for demanding level-detection and industrial sensing applications.

Reliable Capacitive Level Detection for Industrial Processes

Capacitive sensors detect changes in capacitance at the sensing face, enabling them to detect materials that cannot be reliably sensed using conventional inductive proximity switches. The CA18CLL12BP is particularly suited to liquid and dry bulk material detection and can be used with materials including plastics, rubber compounds, powders, granulates and fluids.

The single-step teach-in function allows the sensing distance and switching behaviour to be configured for the application, while automatic NPN/PNP load detection simplifies control-system integration. Humidity compensation, TRIPLESHIELD™ protection and the integrated alarm function further improve reliability by helping identify unsuitable operating conditions or significant contamination at the sensing surface.
