English Introduction: The LJ2-15/211 proximity switch is a high-performance non-contact position detection sensor, widely used in the field of industrial automation. It operates on the inductive principle, generating an alternating magnetic field through an oscillator. When a metal target approaches the magnetic field and reaches the sensing distance, eddy currents are generated within the metal target, causing the oscillation to attenuate or even cease. This change is processed by the subsequent amplification circuit and converted into a switch signal, thereby achieving non-contact detection.

This product offers several advantages. Firstly, it has stable detection performance with adjustable sensing distance and high response frequency, capable of meeting the detection needs of fast-moving objects. Secondly, its housing is made of high-strength engineering plastic and metal composite materials, and the internal components are sealed to provide resistance to vibration, oil contamination, and electromagnetic interference. It can operate stably in a wide temperature range. In addition, the LJ2-15/211 proximity switch offers convenient installation options, supporting flexible adjustments in horizontal or vertical directions to meet the installation requirements of different equipment.

In terms of application, the LJ2-15/211 proximity switch is suitable for various scenarios such as machine tool positioning, conveyor belt material detection, packaging machine counting, and automated assembly lines. Its compact structure and long-life design are particularly ideal for integration into space-limited industrial equipment, significantly reducing equipment maintenance costs and improving production efficiency.
