The FG4SS-1000G-90G-NG encoder is another legacy model that has been discontinued and is no longer available for direct purchase. Many customers in the metallurgical and steel industry continue to depend on this model, which creates major procurement challenges. To solve this problem, we offer fully customized replacement solutions based on 1:1 specifications. These alternatives are designed to be plug-and-play, ensuring compatibility with existing equipment and eliminating the need for redesign. With our fast production process, customers can expect delivery within 15 working days, helping reduce downtime and procurement pressure.
This model was particularly valued in heavy-duty industrial settings, where robust performance and precision were essential. The FG4SS-1000G-90G-NG provided accurate incremental feedback, supporting automation systems, steel rolling equipment, and industrial drives operating under extreme conditions. Despite being out of production, many facilities continue to rely on it because of its proven stability and reliability. Our replacement encoders are built to replicate these critical characteristics, providing a secure and long-term solution for ongoing operations.
