We offer a fully customized 1:1 replacement solution for the C-FG40KK-1024G-90G-NG-S encoder, designed specifically to resolve sourcing difficulties and legacy model unavailability. This tailored approach follows the exact mechanical and electrical specifications of the original encoder, ensuring that every mounting detail, shaft dimension, output characteristic, and electrical connection is reproduced accurately. Because of this one-to-one engineering, the replacement unit can be installed immediately without modification, providing a seamless transition for users who need to maintain existing systems without redesigning supporting machinery or control interfaces.
Since the introduction of this replacement program, customers from numerous international markets have shown strong interest and trust in our customized encoder manufacturing. End users across the Middle East, Russia, Indonesia, Southeast Asia, Brazil, and Ukraine have commissioned non-standard builds to solve operational challenges caused by discontinued encoders. The consistently positive feedback is largely driven by the performance stability of our products and our ability to maintain a practical 15-working-day production cycle, which helps reduce downtime and ensures timely equipment restoration in demanding industrial environments.
