Product Description

The LJ12A3-4-Z/BY sensor is a robust 12mm inductive proximity switch designed for industrial automation applications. This compact device features an NPN/PNP output configuration, enabling direct integration with PLCs and control modules. Operating within a wide voltage range of 10-30V DC, it maintains reliable performance across temperatures from -25°C to +70°C. The sensor offers a 4mm detection distance for metallic objects, making it ideal for position sensing in machinery, conveyor systems, and assembly lines. Its IP67-rated housing ensures durability in harsh environments, while the short-circuit protection enhances operational safety. Though optimized for ferrous metal detection, its limitation lies in reduced sensitivity with non-metallic targets. With no required maintenance and simple installation, this proximity switch delivers cost-effective precision for manufacturing and automotive industries.
