Why Choose the Carlo Gavazzi CA18HLF08NA Capacitive Proximity Sensor?
The Carlo Gavazzi CA18HLF08NA is an industrial M18 flush-mountable capacitive proximity sensor from the TRIPLESHIELD™ range, designed for reliable non-contact detection of metallic and non-metallic materials. Its adjustable 3–8 mm sensing range makes it suitable for presence detection, level monitoring and material sensing across industrial automation applications.
Designed for 10–40 V DC operation, the CA18HLF08NA provides complementary NPN NO + NC outputs with an output current of up to 200 mA. Capacitive sensing technology enables detection of materials such as liquids, powders, granulates, plastics, glass, paper and metals, providing greater application flexibility than proximity sensors intended solely for metallic targets.
The sensor features a chemical-resistant M18 × 1 polypropylene housing, flush-mountable construction and a fixed 2 m PVC cable. A 30 Hz operating frequency, yellow LED indication, high noise immunity, IP67 protection and integrated short-circuit, reverse-polarity and transient protection support dependable operation in demanding industrial environments.
