The FG4S‑360G‑90G‑NG incremental encoder is a robust feedback device widely used in heavy industrial applications such as steel mills, rolling lines, and metallurgical automation systems. With increasing difficulty in sourcing this discontinued model, a fully customized 1:1 replacement solution has been developed to match its original mechanical dimensions, shaft configuration, output signals, and resolution, ensuring seamless integration into existing machinery.
Engineered with industrial-grade materials and reinforced bearings, this replacement encoder delivers long-term durability, high vibration resistance, and precise performance in harsh operational environments. It restores the original equipment’s functionality while enhancing resilience against heat, dust, and mechanical stress, supporting uninterrupted production even in demanding conditions.
The custom solution has been successfully implemented across regions including Southeast Asia, South America, the Middle East, and Russia, helping industries maintain continuous operation despite global supply constraints. Tailored configurations are available to meet specific operational requirements, offering a reliable path to extend equipment service life while preserving existing system designs.
