The FGH6K-2500G-90G-NG/50P is another prominent member of the heavy-duty encoder family, designed for high-resolution feedback and precise control in industrial automation systems. We now provide a compatible alternative product designed and manufactured to meet the same technical requirements. Our 1:1 parameter customization ensures that users can easily replace the original encoder without modification to the mechanical or electrical setup. Fast production cycles ensure short lead times to help clients avoid costly downtime in mission-critical environments.
In heavy industrial applications such as metallurgy, wind turbines, and lifting machinery, this encoder demonstrates excellent reliability and resistance to mechanical stress. The replacement version maintains identical output accuracy while incorporating enhanced structural sealing and optimized bearing systems for longer service life in challenging environments.
