Product Description

The LJ12A3-4-Z/DX is a rugged 4mm inductive sensor designed as a 3-wire proximity switch for industrial automation. Operating within 10-30V DC, it offers stable performance in harsh environments (-25°C to +70°C). Featuring a detection range of 4mm, the sensor provides a single NPN or PNP output (selectable) via a 3-wire configuration, enabling direct integration with PLCs or control modules. Its compact, corrosion-resistant housing ensures reliability in manufacturing, automotive, and machinery applications. Advantages include high shock resistance, immunity to electromagnetic interference, and precise object detection. While lacking built-in communication interfaces, it supports simple wiring for basic proximity sensing tasks. The sensor requires no batteries and is ideal for metal object detection with fast response times and minimal maintenance.
