Inductive Proximity Sensor Lj12A3-4-Z/BX NPN Switch DC 6-36 Volt

The LJ12A3-4-Z/BX Inductive Proximity Sensor NPN Switch DC 6-36V is a non-contact metal detection sensor designed for automation, robotics, CNC machines and industrial control applications. It detects nearby metallic objects without physical contact, helping reduce mechanical wear and improve switching reliability. The cylindrical threaded metal body allows easy mounting and position adjustment using the supplied nuts and washers. This sensor uses a three-wire NPN normally open output and operates from a wide 6V to 36V DC supply range. Its compact design, attached cable and reliable inductive sensing make it suitable for object detection, position sensing, limit switching and machine automation projects.
