The LJ18A38Z/BX 8mm Approach Sensor is a compact inductive proximity sensor with a NPN normally open (NO) switch output designed for DC operation from 6 to 36 V. It provides reliable, non contact metal sensing in a small 8 mm form factor, making it well suited for tight spaces and retrofit projects in automation and manufacturing environments. Key benefits Non contact sensing reduces wear and maintenance for long service life in automated systems. Wide DC supply range (636 V) allows straightforward integration with standard PLCs, controllers, and other digital inputs. NPN normally open output enables simple wiring to common lowside input stages and logic circuits. Small 8 mm diameter body fits into compact equipment and crowded assemblies. Robust, industrially oriented design optimized for reliable switching in everyday machine environments. Quick and straightforward replacement for traditional mechanical switches in suitable applications.
