The FGH4K-2000G-90G-NG/20P is a robust incremental encoder primarily designed for heavy-duty applications in the metallurgical and steel industries. Due to the limited availability of the original model, we provide a custom-engineered replacement solution that replicates the exact parameters of the original design. Our 1:1 production ensures identical electrical characteristics, mechanical dimensions, and output performance, making it a seamless fit for existing machinery. This replacement product helps users overcome procurement challenges and maintain continuous operation without system modification, all while benefiting from significantly reduced delivery time.
Engineered to withstand harsh industrial environments, the FGH4K-2000G-90G-NG/20P excels in reliability and signal stability even under vibration, heat, and contamination typical of steel mill operations. Its heavy-duty construction ensures long-term durability, and its precision output makes it suitable for drive control, conveyor feedback, and automation systems where consistent performance is critical. With proven compatibility and reliable quality, our custom replacement solution has become a trusted choice among customers seeking dependable alternatives for obsolete or hard-to-find encoders.
