The LJ24A3-10-Z/BY is a 3-wire PNP normally open (NO) inductive proximity sensor designed for non-contact detection of metallic objects within a 10mm range. Operating from a 6-36VDC supply, it integrates directly with PLCs, industrial controllers, and 24V DC automation systems.

Features

  • PNP (Sourcing) Normally Open (NO) 3-wire output for direct PLC input compatibility.
  • 10mm nominal detection distance for ferrous and non-ferrous metal objects.
  • Robust brass-nickel plated housing with IP65 rating for dust and water jet protection.
  • Wide 6-36VDC operating voltage range for flexible system integration.
  • Includes reverse polarity protection to prevent damage from incorrect wiring.

Description

This inductive proximity sensor operates on the principle of electromagnetic induction, generating an oscillating field from its sensing face. When a metallic object enters this field, eddy currents are induced, causing a change in oscillation amplitude that is detected and converted into a solid-state PNP switching signal. The robust brass-nickel plated housing and ABS sensing face ensure reliable operation in industrial environments with exposure to oil, coolants, and particulate matter.

Designed for continuous duty, the sensor features a switching frequency suitable for high-speed counting and positioning applications. Its 3-wire configuration simplifies wiring, requiring only a DC power supply and a load (such as a PLC digital input) connected to the output line. The integrated reverse connection protection safeguards the internal electronics from accidental miswiring, enhancing system reliability.

Key Features

  • Non-contact inductive sensing for wear-free, long-life operation.
  • High-strength brass-nickel plated housing resists corrosion and mechanical impact.
  • IP65 ingress protection rating ensures reliable performance in dusty or wet industrial conditions.
  • Wide operating voltage range (6-36VDC) accommodates common 12V, 24V, and 36V control systems.
  • Reverse polarity protection circuit prevents damage from incorrect power connection.
  • LED status indicator provides visual confirmation of power and output state.
  • Compact cylindrical M24 housing with standard mounting threads for easy installation.
  • Optimized performance-to-cost ratio for high-volume automation applications.

Applications

  • Machine tool position sensing for end-of-travel or tool presence detection.
  • Conveyor belt systems for counting metallic parts or detecting product position.
  • Automated assembly lines for verifying the presence of metal components.
  • Packaging machinery for detecting metal lids, cans, or foil seals.
  • Material handling equipment for pallet positioning and robotic arm end-effector sensing.

Frequently Asked Questions

What is the wiring diagram for this 3-wire PNP sensor?

Connect the brown wire to your positive DC supply voltage (6-36VDC), the blue wire to the DC common (ground), and the black wire to your load (e.g., a PLC digital input). The load should then be connected back to the DC common. The black output wire will source current to the load when a metal target is detected, as this is a PNP (sourcing) normally open output.

Can this sensor detect non-ferrous metals like aluminum or copper?

Yes, inductive proximity sensors can detect all conductive metals, but the effective sensing distance (Sn) is reduced for non-ferrous metals compared to steel. For this 10mm nominal range sensor, the sensing distance for aluminum is typically 40-50% of the rated Sn, or approximately 4-5mm. Always test with your specific target material for final positioning.

What is the difference between PNP and NPN output types?

PNP (sourcing) outputs switch the positive voltage to the load, common in European and PLC systems. NPN (sinking) outputs switch the ground path. This LJ24A3-10-Z/BY model is PNP Normally Open (NO), meaning the output line becomes internally connected to the positive supply when a target is detected, providing a 'high' signal to the connected input.

Is this sensor suitable for outdoor use?

The IP65 rating provides protection against dust ingress and low-pressure water jets from any direction, making it suitable for damp, dusty indoor industrial environments. It is not submersible or rated for prolonged direct rainfall or high-pressure washing (IP67/IP69K), so for true outdoor exposure, additional protective housing is recommended.
