English Product Description
The LJ2-15G/224 proximity sensor (Model LJ215G224) is an industrial-grade inductive proximity switch designed for non-contact detection of metallic objects. Operating on eddy current principle, it generates an oscillating electromagnetic field through built-in oscillator circuitry. When a metal target enters its 15mm sensing range, the field disturbance triggers a switching response. The device features epoxy-encapsulated rectangular housing with IP6 protection rating, ensuring reliable operation in dusty or vibrating environments. Key components include oscillator, amplifier circuit and switching output stage. 67
Technical Specifications
This sensor demonstrates high response frequency (500Hz typical), excellent repeatability and short transition time. It supports both NO/NC output modes with 3-wire connection (brown/blue for power supply, black for signal output), compatible with PLC control systems. Operating voltage ranges from 6-36V DC to 220V AC with 400mA output capacity. The contactless design eliminates mechanical wear, significantly extending service life compared to mechanical switches. Special potting technology provides resistance against water, oil and chemical corrosion. 416
Application Scenarios
Widely implemented in machine tools, metallurgical equipment, textile machinery and packaging lines, the LJ2-15G/224 performs position sensing, stroke control and speed monitoring. Typical applications include detecting metal components on automated assembly lines, monitoring conveyor belt operations, and providing limit switch functionality for hoists or valve positioning. It reliably detects various conductive metals (iron, aluminum, copper etc.) without physical contact, preventing mechanical damage to targets. Installation flexibility allows integration into diverse industrial control systems. 921
