The FGHJ40K-1024G-90G-NG/20P is a robust incremental encoder designed for heavy-duty industrial applications such as steel rolling mills, metallurgical automation systems, and high-load conveyor drives. With the original model increasingly difficult to source, we offer a fully customized 1:1 replacement solution. Our encoder matches all critical specifications of the original, including mechanical dimensions, shaft interface, pulse resolution, and electrical output, ensuring seamless integration with existing systems. Built with durable materials and reinforced components, it delivers reliable performance even under vibration, high temperatures, and dusty industrial conditions. The efficient production process allows for rapid delivery, helping customers quickly resolve procurement challenges and minimize downtime.
This replacement solution has already been successfully deployed in multiple international markets, including South America, Southeast Asia, Indonesia, the Middle East, and Russia. In these regions, our encoders support continuous operation in demanding industrial environments, providing stable and accurate feedback for heavy-duty machinery. By offering precise replication of the original model with optional customization, our solution ensures long-term operational reliability and adaptability for diverse metallurgical and steel industry applications.
