The FGH40K-600G-90G-NG/20P is a precision heavy-duty incremental encoder widely used in the steel, metallurgy, and heavy machinery industries. As this model has become increasingly difficult to obtain, we offer a fully customized 1:1 replacement solution that replicates all original specifications — including mechanical dimensions, pulse resolution, and electrical output configuration. Our encoder replacement allows for seamless installation into existing systems without modification, ensuring reliable performance and compatibility. With a streamlined production process, we can deliver orders quickly, helping customers overcome long procurement cycles and avoid costly equipment downtime.
Known for its reliability and accuracy, the FGH40K-600G-90G-NG/20P performs exceptionally well in high-vibration, high-temperature, and dusty industrial environments. Our custom-built replacement version preserves these critical performance features while providing flexibility for non-standard customization, such as alternative shaft sizes, cable directions, or connector types. This ensures long-term durability and stable feedback for heavy-duty drives, rolling mills, and automated control systems.
