Why Choose the Carlo Gavazzi CA18CAF08NA Capacitive Proximity Sensor?
The Carlo Gavazzi CA18CAF08NA is a high-performance M18 flush-mount capacitive proximity sensor designed for reliable non-contact detection in industrial automation, material handling and level-sensing applications. Part of the advanced Carlo Gavazzi CA18CAF 4th Generation TRIPLESHIELD™ series, it combines an 8 mm nominal sensing distance, complementary NPN outputs and robust environmental protection in a compact threaded cylindrical housing.
The sensor provides an adjustable sensing range of approximately 2–10 mm, with sensitivity adjustment through a multi-turn potentiometer. Capacitive sensing technology allows the CA18CAF08NA to detect both conductive and non-conductive materials, including metals, plastics, glass, liquids, powders and granular products, making it a versatile choice for industrial presence and level detection.
Operating from a 10–40 V DC supply, the CA18CAF08NA provides complementary NPN normally open and normally closed outputs with an output current capability of up to 200 mA. The sensor is supplied with a 2 m PVC cable and features an M18 × 70 mm PBT housing with IP67, IP68 and IP69K protection, enhanced EMC performance and ECOLAB approval for demanding industrial environments.

Reliable Capacitive Detection for Industrial Automation
Capacitive proximity sensors detect changes in capacitance when an object enters the sensor's electrical field. Unlike inductive proximity sensors, which are primarily intended for metallic targets, capacitive sensors can detect a broad range of conductive and non-conductive materials. This makes the CA18CAF08NA particularly useful for monitoring plastics, glass, liquids, powders and granular materials as well as metallic objects.
The CA18CAF08NA combines adjustable sensitivity with Carlo Gavazzi's 4th Generation TRIPLESHIELD™ technology to provide stable detection in demanding automation applications. Its complementary NPN normally open and normally closed outputs provide additional wiring flexibility, while the high environmental protection ratings and wide operating temperature range support reliable installation on industrial machinery and process equipment.
Typical Applications
- Liquid and bulk-material level detection.
- Plastic, glass and non-metallic object detection.
- Packaging and processing machinery.
- Food and beverage production equipment.
- Conveyor presence and position sensing.
- Container, hopper and vessel level monitoring.
- Automated manufacturing and assembly systems.
- Industrial material handling equipment.
