Description

The LJ8A3-2-Z/EX operates on the inductive sensing principle, generating an electromagnetic field to detect the presence of ferrous and non-ferrous metals without physical contact. Its 2-wire DC design provides a normally open (NO) switching output, making it straightforward to interface with PLCs, relays, and microcontroller inputs in 24V industrial control systems.

Constructed with a brass-nickel plated body and an ABS plastic sensing face, this sensor is built for mechanical durability and resistance to industrial contaminants. The IP65 ingress protection rating guarantees reliable operation in environments with dust exposure and low-pressure water jets, suitable for machine tools, conveyor systems, and automated assembly lines.

Key Features

  • Industrial-Grade Construction: Brass-nickel plated housing with ABS sensing face for long-term durability in harsh conditions.
  • Precise Non-Contact Detection: Reliably senses metallic objects at a nominal distance of 2mm, minimizing wear and tear.
  • Simplified 2-Wire DC Design: Normally open (NO) output configuration reduces wiring complexity for standard industrial applications.
  • Broad Voltage Compatibility: Supports a wide 6–36V DC input range, accommodating common 12V and 24V control systems.
  • Enhanced Electrical Protection: Integrated reverse polarity protection prevents damage from incorrect power connections.
  • Environmental Sealing: IP65 rating protects against dust ingress and water jets for stable operation.

Applications

  • Position verification and end-of-travel detection in CNC machines and automated actuators.
  • Metal part presence sensing on conveyor belts and assembly lines in manufacturing.
  • Safety interlock and door/window position monitoring in industrial machinery.
  • Object counting and sorting systems for metallic components.
  • Integration into PLC-based control panels for 24V DC automation systems.

Frequently Asked Questions

What is the output type of the LJ8A3-2-Z/EX sensor?

The LJ8A3-2-Z/EX provides a 2-wire DC normally open (NO) output. In its resting state (no target present), the circuit is open. When a metallic object enters the 2mm detection range, the switch closes, completing the circuit to the load.

What power supply voltage does this sensor require?

This inductive proximity sensor operates on a wide DC voltage range from 6V to 36V. This makes it compatible with common industrial control voltages like 12V DC and 24V DC systems without requiring an additional voltage regulator.

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

Yes, inductive proximity sensors like the LJ8A3-2-Z/EX can detect both ferrous (iron, steel) and non-ferrous metals (aluminum, brass, copper). However, the effective sensing distance (Sn) may be reduced for non-ferrous metals compared to ferrous targets.

How do I wire the 2-wire LJ8A3-2-Z/EX sensor?

Wiring is straightforward: connect one wire to the positive DC supply voltage (6-36V) and the other wire to the load (e.g., a PLC input or relay coil). The load's other terminal connects to the DC supply negative. The sensor includes reverse connection protection, but correct polarity is recommended for proper operation.

What does the IP65 rating mean for installation?

The IP65 rating indicates the sensor is dust-tight (6) and protected against low-pressure water jets from any direction (5). This allows for reliable use in industrial environments with particulate contamination and occasional water splash, but it is not suitable for submersion.
