The LJ5A3-1-Z/BY is a PNP normally open (NO) inductive proximity sensor designed for non-contact detection of metallic objects within a 1mm range. Operating from a 10–30VDC supply, it integrates seamlessly into industrial PLCs and 24V DC control systems for automation tasks.

Features

  • PNP Normally Open (NO) output for direct interface with PLC sinking inputs.
  • 1mm nominal detection distance for precise metal object sensing.
  • Robust brass-nickel plated housing with IP65-rated environmental protection.
  • Wide 10–30VDC operating voltage range compatible with standard industrial power rails.
  • 150mA maximum output current capable of driving small relays or indicators directly.

Description

The LJ5A3-1-Z/BY operates on the electromagnetic induction principle, generating an oscillating field from its ABS sensing face. When a metallic target enters the 1mm detection zone, it dampens the oscillation, triggering the internal solid-state switch to change state. This provides a reliable, wear-free alternative to mechanical limit switches.

Engineered for harsh industrial environments, its brass-nickel plated housing offers corrosion resistance and mechanical durability. The IP65 rating ensures protection against dust ingress and low-pressure water jets, making it suitable for machine tools, conveyor systems, and automated assembly lines where reliability is critical.

Key Features

  • Precision Non-Contact Sensing: Detects ferrous and non-ferrous metals without physical contact, eliminating mechanical wear.
  • Industrial-Grade Construction: Brass-nickel plated metal housing provides superior impact and corrosion resistance.
  • Enhanced Electrical Protection: Integrated reverse polarity protection safeguards the sensor from wiring errors.
  • Stable Switching Performance: Consistent 1mm sensing distance with minimal hysteresis for repeatable operation.
  • Broad Voltage Compatibility: Functions reliably across the entire 10 to 30VDC range, accommodating typical 12V and 24V DC systems.
  • Ready for Harsh Environments: IP65 sealing protects internal electronics from dust and water splashes.

Applications

  • Machine Tool Position Verification: Detecting the presence/position of metal workpieces in CNC lathes or milling machines.
  • Conveyor System Object Counting: Monitoring metal parts or pallets on automated production lines.
  • Robotic End-Effector Feedback: Providing precise position confirmation for grippers or tools in robotic arms.
  • Safety Door Interlocking: Ensuring machine guard doors are securely closed before enabling operation.
  • Automated Assembly Verification: Confirming the presence of metal components (screws, brackets) in assembly jigs.

Frequently Asked Questions

What is the output type of the LJ5A3-1-Z/BY sensor and how do I wire it?

This sensor has a PNP (sourcing) Normally Open (NO) output. The brown wire connects to DC+ (10-30VDC), the blue wire to DC- (0V), and the black wire is the switched output. When a metal target is detected, the black wire switches to the supply voltage (sourcing current) to drive your PLC input or load.

What metals can this inductive sensor detect and what is its exact sensing range?

It detects both ferrous (iron, steel) and non-ferrous (aluminum, copper) metals, though the sensing distance may vary slightly with material type. The nominal detection distance (Sn) is 1mm, with a recommended operational 'setting distance' of 0 to 0.7mm to ensure reliable switching and account for installation tolerances and temperature drift.

Is this sensor protected against wiring mistakes and harsh environments?

Yes. It features reverse polarity protection on the power lines to prevent damage from incorrect connections. The brass-nickel plated housing and IP65 rating provide robust protection against dust, oil, coolants, and water jets, making it suitable for demanding factory floor and machinery applications.
