LJA12M-5N1 Inductive Proximity Switch Introduction
Product Overview
The LJA12M-5N1 is a non-contact detection device based on electromagnetic induction principle, featuring DC 3-wire NPN output configuration with normally open (NO) operation mode. Designed for non-flush mounting applications, this sensor reliably detects metallic objects in industrial automation systems through electromagnetic field variation, eliminating mechanical wear for extended service life.
Key Features
- Stable Detection: Equipped with high-frequency oscillation circuit, providing 2mm±10% sensing distance for ferrous metals with optimized sensitivity.
- Robust Construction: Epoxy encapsulated housing achieves IP67 protection rating, operational in -25℃ to +70℃ environments with resistance to oil, dust and vibration.
- Circuit Protection: Built-in reverse polarity and overload protection supports 10-30VDC wide voltage input, delivering ≤200mA output current for PLC compatibility.
- Installation Flexibility: M12 cylindrical threaded housing (40mm length) with dual-color LED status indicator allows axial or radial mounting orientations.
Technical Specifications
• Output Type: NPN 3-wire NO
• Target Material: Ferrous metals (steel, iron)
• Supply Voltage: DC 10-30V±10%
• No-load Current: ≤10mA
• Response Frequency: 200Hz
• Cable: 2m PVC jacket (Brown: +V, Blue: -V, Black: Signal)
Applications
Ideal for position sensing in automated production lines, machine tool safety systems, logistics sorting equipment and packaging machinery. Particularly suitable for metal component detection and equipment status monitoring requiring contactless operation.
Safety Notice
Maintain clean sensing surface and avoid strong electromagnetic interference sources during installation. Verify power supply polarity before wiring to prevent reverse connection.
