Why Choose the Carlo Gavazzi CA18CLL12BPM1 Capacitive Proximity Sensor?

The Carlo Gavazzi CA18CLL12BPM1 is an advanced M18 capacitive proximity and level sensor with Teach-In designed for reliable detection of liquids, dry bulk materials and non-metallic targets in industrial automation applications. Part of the Carlo Gavazzi CA18CLL TRIPLESHIELD™ series, it combines an adjustable sensing range of 0.5–12 mm, automatic NPN/PNP load detection and configurable NO/NC switching in a robust threaded cylindrical housing.

The CA18CLL12BPM1 is particularly optimised for level detection through plastic and rubber materials. Its single-step Teach-In function allows the sensing point to be configured using the sensor push-button or remotely through the COM input, simplifying commissioning and making it easier to adapt the sensor to different containers, materials and operating conditions.

Operating from a 10–40 V DC supply, the sensor provides automatic NPN/PNP output detection with selectable normally open or normally closed switching. Humidity compensation, an alarm output, TRIPLESHIELD™ sensor protection and an IP68 enclosure support reliable operation in demanding applications, while the 4-pole M12 plug provides convenient installation and replacement.

Reliable Teach-In Level Detection for Industrial Automation

Capacitive sensors detect changes in capacitance caused by a target entering the sensor's electrical field. This enables the CA18CLL12BPM1 to detect materials that cannot be reliably sensed using conventional inductive technology, including liquids, plastics, rubber, powders and granular products. It is particularly useful for detecting material levels through non-metallic container walls.

The single-step Teach-In system simplifies sensitivity adjustment and can be operated locally or through the COM input for remote configuration. Combined with humidity compensation and TRIPLESHIELD™ protection, this helps maintain stable sensing performance where environmental conditions, container materials or product characteristics could otherwise make capacitive level detection more challenging.

Typical Applications

• Liquid level detection through plastic containers.
• Dry bulk material and powder level monitoring.
• Plastic and rubber processing machinery.
• Hopper and vessel level detection.
• Packaging and processing equipment.
• Granulate and pellet detection.
• Industrial presence and material detection.
• Automated manufacturing and process control systems.
