The FGH6K-5000G-90G-NG-V/50P is a robust heavy-duty encoder designed for industrial environments requiring exceptional durability and precision. To support users facing sourcing or lead-time challenges, we provide a custom-built 1:1 replacement solution that matches the original encoder’s electrical, mechanical, and functional parameters. Our replacement models are built to ensure seamless compatibility with existing systems, allowing direct installation without modification. The short production lead time and stable supply capability help customers maintain equipment uptime and avoid costly delays in critical applications.
This encoder series is highly valued in the metallurgical and heavy machinery industries, where it operates reliably in steel rolling mills, conveyor systems, and continuous casting lines. Its rugged construction, vibration-resistant design, and advanced signal output make it ideal for environments with dust, oil, and mechanical stress. The encoder’s precision feedback performance ensures smooth speed control and accurate positioning, essential for production efficiency and system safety. Our replacement units have already been successfully exported and deployed in the Middle East, Russia, Indonesia, Southeast Asia, and South America, helping clients in these regions solve sourcing and operational challenges with proven reliability.
