English Introduction
The Xinling LJM24M-10P1 is a cylindrical inductive proximity sensor with non-flush mounting design, featuring PNP 3-wire DC output and normally open (NO) contact configuration. This metal detection device operates on electromagnetic induction principle, offering reliable object sensing within 10mm range for ferrous materials like iron, steel and copper. Its compact 24mm diameter brass-nickel housing contains oscillation circuit that generates stable high-frequency electromagnetic field for precise position detection. 2224
With 0.4KHz response frequency and ±15% detection distance tolerance, this industrial sensor demonstrates quick reaction to target movement while maintaining consistent performance. The 1.5-meter PVC cable facilitates flexible installation in automated systems, compatible with DC 6-36V power supply. Robust construction includes IP54 rated enclosure and heat-resistant ABS sensing face, ensuring durability in harsh environments containing dust, moisture or oil contamination. 1015
This proximity switch excels in machine tools, packaging lines and material handling applications where non-contact metal detection is required. Typical implementations include position verification of robotic arms, product counting on conveyors, and safety interlocking systems. The PNP output seamlessly interfaces with PLCs, servo drives and other control devices, while polarized wiring prevents incorrect connections. Advanced circuit design incorporates surge protection and reverse polarity safeguards for enhanced reliability. 722
Notable features include vibration resistance, spark-free operation, and wide temperature tolerance from -25°C to +70°C. The optimized electromagnetic field minimizes mutual interference when multiple sensors are installed adjacently. Compared to mechanical limit switches, this solid-state device provides maintenance-free operation with over 10 million switching cycles, significantly reducing downtime in production environments. 114
