Why Choose the Carlo Gavazzi CA18CLN12NA Capacitive Proximity Sensor?

The Carlo Gavazzi CA18CLN12NA is an M18 non-flush capacitive proximity sensor designed for reliable non-contact detection of conductive and non-conductive materials in industrial automation applications. Part of the Carlo Gavazzi CA TRIPLESHIELD™ series, it combines an adjustable sensing distance of 3–12 mm, complementary NPN outputs and a robust thermoplastic polyester housing.

Capacitive sensing technology enables the CA18CLN12NA to detect a wide variety of target materials, including metals, plastics, glass, liquids, powders and granular products. Its adjustable sensitivity makes it particularly useful where the sensing distance needs to be optimised for different target materials or installation conditions.

Operating from a 10–40 V DC supply, the CA18CLN12NA provides 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 cable and features IP67 environmental protection, a yellow output LED and integrated short-circuit, reverse-polarity and transient protection for dependable industrial operation.

Versatile Capacitive Detection for Industrial Automation

Capacitive proximity sensors detect changes in capacitance when a target enters the sensor's electrical field. Unlike inductive sensors, which are principally intended for metallic targets, capacitive sensors can detect both conductive and non-conductive materials. This makes the CA18CLN12NA suitable for applications involving plastics, glass, liquids, powders, granulates and other materials commonly found in industrial processes.

The adjustable 3–12 mm sensing range allows the sensor to be configured for the target material and application. Its non-flush design provides an extended detection range, while complementary NPN normally open and normally closed outputs give machine builders flexibility when interfacing the sensor with PLCs, relays and other industrial control equipment.

Typical Applications

• Liquid and bulk-material level detection.
• Plastic and glass object detection.
• Powder, granulate and pellet monitoring.
• Packaging and processing machinery.
• Conveyor product presence detection.
• Container, hopper and vessel level monitoring.
• Automated manufacturing and assembly systems.
• General industrial material detection.
