LJ12A3-4Z/BX NPN inductive proximity sensor
LJ12A3-4Z/BX NPN inductive proximity sensor with 4mm detection range—perfect for metal detection, automation, and robotics applications.
Description
The LJ12A3-4Z/BX NPN Inductive Proximity Sensor is a compact and reliable sensor designed to detect metal objects without physical contact. Operating as an NPN normally open (NO) sensor, it provides a digital output signal when a metallic target enters its sensing range, making it ideal for automation, robotics, and industrial control applications.
This sensor features a 3–36V DC supply voltage, a detection distance of 4mm, and a durable cylindrical design for easy installation in machines, conveyors, and robotic systems. Its robust construction ensures stable performance in various environments, even under vibration or dust conditions.
Common applications include metal detection, position sensing, conveyor monitoring, industrial automation, and robotics projects. With simple wiring and maintenance-free operation, the LJ12A3-4Z/BX NPN sensor is ideal for both hobbyists and professional engineers.
