LJ8A32ZEX — Compact M8 inductive proximity sensor for contactless metal detection Key specifications Sensing method: inductive (detects metal without contact) Size: M8 compact form factor Sensing distance: 2 mm (optimized for small metal parts) Output options: available in NPN or PNP; normally open (NO) or normally closed (NC) Power compatibility: operates with DC or AC supply Key benefits — why you need it Fits tight spaces: M8 size makes installation possible where larger sensors cannot be used. Flexible integration: choice of NPN/PNP and NO/NC outputs lets the sensor match the input requirements of PLCs, controllers, and existing wiring. Reduces wear and maintenance: non-contact sensing eliminates mechanical switch wear, lowering downtime and replacement costs. Reliable performance for small parts: a precise 2 mm sensing distance ensures consistent detection of small metal components in automated systems. How it solves common problems Replaces mechanical limit switches to reduce mechanical failure points and maintenance intervals. Adapts to different machine control architectures without needing additional converters or rewiring. Provides repeatable, short-range detection for tasks that require high placement accuracy. Practical applications Small parts conveyor: detect the presence of metal components and trigger sorting, counting, or indexing actions. Tooling and fixturing: verify that a metal workpiece is correctly positioned before machining or assembly. Machine guards and interlocks: detect metal doors or guards to enable safe machine operation and interlock sequences. Standout points Compact M8 housing combined with 2 mm sensing distance for precise detection in confined spaces Multiple output and contact-mode options for straightforward compatibility with a wide range of control systems Contactless operation for lower maintenance and longer service life Model reference LJ8A32ZEX
