LJC18A3-B-Z/BX Capacitive Proximity Sensor – 6–36V

The LJC18A3-B-Z/BX capacitive proximity sensor is designed for reliable non-contact detection of objects in industrial automation systems. It detects both metallic and non-metallic materials such as plastics, liquids, wood, and powders using capacitive sensing technology. The sensor operates with a wide 6–36V DC supply and provides a stable normally-open output signal for control circuits and PLC inputs. Its threaded cylindrical metal housing ensures secure installation and resistance to dust and moisture in demanding environments. Ideal for level detection, object sensing, and automation control applications.
