The FG4S-2000G-90G-NG encoder is no longer in production, making it increasingly difficult for users to maintain machinery that still depends on this model. To address this challenge, we provide non-standard custom replacement solutions engineered with 1:1 parameters. This approach ensures that the replacement encoder performs identically to the original, allowing customers to continue using their equipment without modifications. Thanks to our optimized production schedule, we are able to deliver custom encoders within 15 working days, minimizing downtime and easing procurement challenges.
From an application perspective, the FG4S-2000G-90G-NG was designed for use in heavy-duty industrial environments such as steel plants, metallurgical lines, and industrial automation systems. Its rugged design and reliable incremental output made it an essential component for ensuring stable performance in rolling mills and large machinery. Even after being discontinued, this encoder remains critical for facilities that depend on long-running equipment. Our customized replacement solutions replicate the original specifications, providing a practical and efficient way to keep equipment fully operational.
