Description

The LJC18A3-B-Z/BX operates on the inductive sensing principle, generating an electromagnetic field to detect the presence of metallic targets without physical contact. Its NPN open-collector output switches to ground when a target is detected, providing a clean digital signal for machine control and position feedback.

Constructed for industrial durability, the sensor is housed in a nickel-plated brass body capable of withstanding vibrations, oil mist, and brief washdowns. An integrated LED provides visual status indication for commissioning and troubleshooting. The unit’s -25°C to +65°C operating temperature range ensures reliable performance in challenging factory environments.

Key Features

  • Inductive sensing technology for reliable metal detection.
  • NPN normally open (NO) transistor output compatible with common PLC input modules.
  • Wide 10-30V DC operating voltage range for flexible power supply integration.
  • High 200mA output current enables direct control of small loads.
  • 18mm threaded barrel (M18 x 1) for easy panel or bracket mounting.
  • Integrated status LED for immediate operational feedback.
  • Extended 1.2-meter PVC-jacketed cable simplifies wiring.
  • Durable construction suitable for automated machinery and harsh industrial settings.

Applications

  • Position sensing and end-of-travel detection on automated linear actuators.
  • Metal part presence verification in assembly lines and conveyor systems.
  • Tool breakage detection and spindle orientation in CNC machining centers.
  • Safety interlock and guard door monitoring in industrial machinery.
  • Object counting and sorting in material handling and packaging equipment.

Frequently Asked Questions

What is the wiring configuration for the NPN NO output on this sensor?

The sensor's brown wire connects to the positive DC supply (10-30V), the blue wire to the common ground (0V). The black wire is the NPN output; it switches to ground (sinks current) when a metal target is detected within range. Connect the black wire to your PLC input or load, with the other side of the load connected to the positive supply.

Can this sensor detect both steel and aluminum objects?

Yes, this inductive proximity sensor is designed to detect both ferrous (like steel and iron) and non-ferrous metals (like aluminum, copper, and brass). The effective sensing distance may vary slightly depending on the target material's conductivity and permeability, with ferrous metals typically providing the maximum rated 10mm range.

What is the recommended mounting procedure for the M18 threaded barrel?

Use a standard M18 x 1 metric nut to secure the sensor. Ensure the sensing face is flush with or slightly recessed from the mounting surface to prevent physical damage. Maintain the specified lateral and axial clearance distances from other metal objects to avoid false triggering and ensure optimal sensing performance.
