The FGHJ40S-1024G-90G-NG/20P encoder is a robust model designed for high-precision industrial motion control and feedback systems. Our 1:1 customized replacement solution is manufactured to match the original unit’s electrical and mechanical parameters — including 1024 pulse resolution, shaft configuration, and connector type. With a standard lead time of 10 working days, the replacement encoder is engineered to ensure seamless installation and long-term reliability in harsh environments such as steel processing, cranes, and marine systems.

Our replacement solution has already been successfully deployed in South America, Southeast Asia, Indonesia, the Middle East, and Russia. These installations have helped many industrial users resolve compatibility and operational challenges in legacy control systems. The enhanced bearing design and upgraded signal stability make it an ideal choice for maintaining consistent accuracy under vibration and high load conditions.
