The FG4KK-5000G-90G-NG is a robust heavy-duty incremental encoder widely used across steel plants, rolling mills, metallurgical equipment, and other heavy machinery. With a 5,000-pulse resolution, it provides accurate speed monitoring, motor feedback, and position control, ensuring smooth operation of machinery under high-load, high-temperature, and high-vibration conditions. Its heavy-duty design allows for long service life and resistance to harsh industrial environments, making it ideal for critical automation and process control systems.
As this model has become hard-to-source, we developed a fully compatible replacement encoder that duplicates the original’s key specifications. This ensures a direct, drop-in solution, eliminating the need for extensive system modifications or downtime. The replacement unit offers reliable incremental output, robust mechanical integrity, and full compatibility with existing industrial systems, providing confidence in operations where precision and durability are paramount.
