The C-FG40KK‑2048G‑90G‑NG‑S incremental encoder is a precision feedback device widely used in heavy-duty industrial automation and motion control systems. For older or discontinued models, sourcing can be challenging. A custom 1:1 replacement solution has been developed to replicate the original encoder’s mechanical dimensions, mounting interfaces, shaft design, output signals, and electrical characteristics. This ensures seamless integration without modifying existing machinery, wiring, or control software.
This replacement encoder is engineered for demanding applications such as steel production, automated processing lines, and other heavy industrial machinery. With a production lead time of approximately 15 working days, it allows maintenance teams to quickly restore equipment operation. Its stability and reliability have been proven in international deployments, including Southeast Asia, the Middle East, Russia, and Brazil. Custom configurations for pulse rates and operational requirements are also available, ensuring continuity and performance in critical industrial environments.
