The FGH4K-8192G-90G-NG/20P heavy-duty incremental encoder is a high-resolution model designed for demanding industrial applications, particularly in metallurgy, steel rolling mills, and heavy machinery. With the original model becoming increasingly difficult to source, we offer a 1:1 customized replacement solution that matches the original parameters precisely. Our replacement ensures complete compatibility with mechanical mounting, shaft dimensions, electrical output, and pulse resolution, allowing seamless integration into existing systems. The production process is optimized for efficiency, ensuring short delivery times to help customers reduce downtime and address urgent procurement challenges.
In application, the FGH4K-8192G-90G-NG/20P encoder is valued for its high-precision feedback and durability under harsh conditions such as vibration, high temperatures, and dust exposure. Our replacement version maintains these essential characteristics while offering flexible options for shaft types, connectors, and mounting interfaces. This ensures that operators in rolling mills, drive systems, and automated metallurgical equipment can continue to rely on stable and accurate feedback for critical industrial processes. Our solution has already been successfully implemented in regions including the Middle East, Russia, Southeast Asia, Indonesia, and South America, demonstrating its reliability and global applicability.
