LJC18A3 BZ/BX — Capacitive Proximity Sensor (M18, DC, NPN, 10 mm) Key benefits Reliable non-contact detection: capacitive sensing provides consistent switching without mechanical wear. Flexible integration: DC operation with NPN output and selectable NO (Normally Open) or NC (Normally Closed) wiring fits common industrial control systems. Space-efficient mounting: M18 threaded housing simplifies installation into standard sensor clamps and panels. Predictable performance: 10 mm detection range gives clear, repeatable switching distance for short-range presence and position control. What it does and how it helps Function: Acts as a capacitive proximity switch detector that senses objects within a 10 mm range and provides a discrete switching output. Compatibility: Designed for DC-powered control circuits requiring an NPN output stage; available in both NO and NC configurations to match wiring logic. Size and mounting: M18 form factor enables easy replacement or integration into existing M18 fixtures and sensor mounts. Performance: Capacitive sensing offers stable, contactless switching suitable for tight or confined spaces where a compact sensor is needed. Practical attributes Model: LJC18A3 BZ/BX Sensing type: Capacitive proximity sensor switch detector Power: DC operation Output: NPN Contact options: NO (Normally Open) and NC (Normally Closed) Housing size: M18 Detection range: 10 mm Typical applications Conveyor part detection: Detect small components passing a pick-and-place station to trigger downstream robotics or sorting logic. Packaging and level sensing: Monitor fill presence or detect product layers in limited space where non-contact sensing reduces wear. Position sensing in automation: Verify the presence or absence of fixtures, jigs, or assembled components in automated machinery with compact M18 mounting. Installation and selection notes Choose NO or NC model according to required logic for your control circuit. Designed for DC control systems that accept an NPN switching output. M18 housing allows direct mounting into standard threaded sensor holes or clamps for quick replacement.
