Introduction

The LJ12A3-4-Z/BX is a reliable NPN inductive proximity sensor with a 4mm detection range, designed for industrial automation. It operates on DC 6-36V and features a rugged M12 nickel-plated brass housing with IP67 protection.

Key Specifications

  • Detection distance: 4 mm
  • Output: NPN Normally Open
  • Supply voltage: DC 6-36V
  • Switching frequency: ~500 Hz
  • Housing: Nickel-plated brass, M12x1
  • Protection: IP67

Integration

The sensor connects directly to PLC sinking inputs. It is compatible with major PLC brands and can be integrated into IIoT architectures via remote I/O modules.

Predictive Maintenance

While lacking native diagnostics, the sensor supports predictive maintenance through cycle-count analysis and signal integrity monitoring at the edge.

Total Cost of Ownership
