The FGH4KK-2000G-90G-NG/20P is a reliable incremental encoder model used extensively in heavy-duty applications, particularly in the metallurgical and steel processing sectors. As the original version of this encoder has become increasingly difficult to procure, we offer a fully compatible custom replacement solution built with 1:1 specifications. Every detail — from the output signal and mounting interface to the shaft dimensions — is precisely replicated to ensure seamless integration into existing systems. This approach allows customers to resolve procurement challenges and maintain stable equipment performance without redesigning their automation setup. In addition, our production process emphasizes efficiency, allowing for fast delivery while maintaining high product quality.
Our replacement encoders have already been successfully exported to multiple regions, including South America, Southeast Asia, Indonesia, the Middle East, and Russia. They have been applied in numerous metallurgical projects and heavy industrial environments, where they have helped clients solve long-standing operational and supply challenges. Customers in these regions rely on our solutions to minimize downtime and maintain the accuracy and reliability of their systems, even under harsh operating conditions.
