LJ12A3-4Z/BX PNP inductive proximity sensor
LJ12A3-4Z/BX PNP inductive proximity sensor with 4mm detection range—ideal for metal detection, automation, and robotics projects.
The LJ12A3-4Z/BX PNP Inductive Proximity Sensor is a reliable sensor used to detect metal objects without physical contact. Operating as a PNP normally open (NO) sensor, it provides a digital output signal when a metallic target enters its sensing range, making it ideal for automation and control applications.
This sensor features a 3–36V DC supply voltage, a detection distance of 4mm, and a compact cylindrical design for easy integration into machines, robotics, and industrial equipment. Its durable construction ensures stable performance in harsh environments.
Common applications include metal detection, position sensing, automation systems, robotics, and conveyor control. With simple wiring and maintenance-free operation, the LJ12A3-4Z/BX sensor is perfect for both hobbyist and professional projects.
