The FG4S-500G-90G-NG encoder has reached end of life and is no longer manufactured, which makes it extremely difficult for customers to obtain original units. In order to solve this common problem, we provide customized replacement products designed with 1:1 parameters to match the exact specifications of the original encoder. By adopting this approach, our alternative encoders can be directly installed in existing systems without requiring additional engineering changes. This reduces risk and cost for operators who need to keep their equipment running. Our production cycle is optimized to just 15 working days, which allows us to provide a rapid response and ensure stable supply, even when the original encoder is no longer available.
This particular model was frequently used in the steel and metallurgical industry, where incremental encoders must operate under severe conditions while delivering reliable signal output. The FG4S-500G-90G-NG became a trusted choice for many industrial operators due to its durable design and accuracy in applications such as rolling mills, heavy drive systems, and mechanical automation equipment. As legacy machines remain in operation, many customers are reluctant to switch to entirely new platforms and instead prefer compatible solutions. Our customized replacements allow these customers to continue using their equipment with confidence, while avoiding the challenges of discontinued product supply.
