Product Description

The LJ12A3-4-Z/AY is a high-performance LJ12A3 Proximity Sensor designed for industrial automation applications, featuring a 12mm Inductive Sensor range and NPN NO Proximity Switch configuration. Operating within a voltage range of 10-30V DC, this sensor offers reliable detection of metallic objects with a precision detection distance of 12mm. Its compact design supports direct integration into control systems without additional modules, ideal for machinery, assembly lines, and material handling. The sensor operates reliably in temperatures ranging from -25°C to 70°C, ensuring durability in harsh environments. Key advantages include robust construction, high resistance to electromagnetic interference, and a long operational lifespan. However, its inductive nature limits detection to ferrous/metallic targets. The device provides a single NPN output for seamless connectivity to PLCs or controllers, ensuring straightforward installation and maintenance. Suitable for automotive, manufacturing, and packaging industries, it delivers consistent performance in precision positioning and object detection tasks.
