English Introduction: The LJ2P-15/214 proximity switch is an inductive non-contact sensor designed for industrial automation applications. It operates on high-frequency oscillation technology, generating a switching signal when a metal target enters its sensing range. The robust housing ensures reliability in harsh environments, including exposure to oil, dust, and mechanical stress. With a detection distance of 15mm and fast response, it is suitable for high-speed production lines. The switch supports both flush and non-flush mounting, offering flexibility for integration into various equipment. It is ideal for machine tool positioning, conveyor belt counting, and hoist limit detection. The non-contact design minimizes mechanical wear, making it suitable for long-term operational stability.
