KT-20R Magnetic Proximity Switch Product Introduction (English Version)
The KT-20R magnetic proximity switch is an industrial-grade position detection device based on magnetic induction principle, designed for position sensing and control requirements in mechanical equipment and automated production lines. Utilizing non-contact inductive technology, this product triggers signal output through magnetic field variations, demonstrating stable and reliable performance in diverse industrial environments.
Featuring a sealed structure design, the housing combines high-strength engineering plastics with metal composite materials, providing notable impact resistance and dust/water protection. The sensing area integrates an optimized magnetic field detection module capable of accurately identifying magnetic sources at varying distances. Equipped with temperature compensation circuitry, the device maintains consistent detection accuracy within a broad temperature range of -25℃ to 85℃, making it suitable for specialized working conditions such as cold storage facilities and heat treatment workshops.
Functionally, the KT-20R supports dual NPN/PNP output modes, ensuring direct compatibility with mainstream PLC control systems. The sensing distance offers three adjustable levels, achieving a maximum effective detection range of 20mm. An integrated LED status indicator facilitates on-site debugging and fault diagnosis. The wiring terminals incorporate anti-loosening buckle design to maintain secure connections in vibratory environments.
This device finds extensive application in injection molding machine mold positioning, machine tool stroke control, and conveyor belt material detection scenarios. Within packaging machinery systems, it effectively monitors material bin door status, while in automotive manufacturing lines, it coordinates with robotic arms for precise workpiece handling. Rigorous aging tests and load tests confirm consistent signal response stability during continuous operation.
Installation guidelines recommend aligning the sensing surface parallel to the magnet movement trajectory with appropriate safety clearance. Regular cleaning of the sensing surface ensures optimal detection sensitivity. When selecting companion magnets, high-temperature resistant permanent magnetic materials are suggested, with attention to proper polarity alignment as indicated by the product markings.
