HallMagnetschalter NJK — Inductive proximity sensors for compact, reliable metal detection Key benefits Non-contact metal detection reduces mechanical wear and maintenance compared to mechanical switches. Compact M8, M12, and M18 threaded housings make the sensor easy to mount in tight or standardized fittings. NPN output with selectable NO (Normally Open) or NC (Normally Closed) wiring simplifies integration with common PLCs and control circuits. Designed for 24V systems and equipped with SPolInduktion for stable inductive sensing performance. Models NJK5001 and LM8 are available with NPN NO outputs for straightforward, drop-in use when Normally Open behavior is required. What it does and why you need it Detects the presence or position of metallic targets without contact, preventing wear and improving system uptime. Provides a robust electrical output (NPN) compatible with industrial automation inputs and safety circuits. Available in three popular threaded sizes (M8, M12, M18) so you can choose the best fit for your mounting space and mechanical requirements. Important attributes Function: Inductive proximity sensing for metallic targets. Output: NPN (available in NO or NC configurations); NJK5001 and LM8 specifically supplied in NPN NO. Voltage: 24V operation for common industrial control systems. Sizes: M8, M12, M18 threaded housings for easy installation. Feature: SPolInduktion for reliable inductive sensing behavior. Typical applications Conveyor and material handling: detect metal parts passing a sensor point to trigger indexing, counting, or sorting. Industrial automation and machine tooling: confirm position of moving metal components for cycle control or safety interlocks. Robotics and tight-space installations: compact M8/M12 sizes allow placement inside tooling, feeders, or robot end-effectors to monitor part presence. Why choose HallMagnetschalter NJK Straightforward electrical interfacing with 24V and NPN outputs reduces wiring complexity. Multiple sizes and NO/NC options cover a wide range of mechanical and control requirements. NJK5001 and LM8 provide immediate NPN NO choices when Normally Open operation is desired. Ordering notes Confirm required output configuration (NO or NC) and sensor size (M8, M12, M18) when selecting. NJK5001 and LM8 models are available with NPN NO output as standard options.
