For the model FG4L-1024-90G-50/125, we provide a 1:1 replacement solution produced through dedicated non-standard customization. The alternative unit is engineered to replicate the original encoder’s mechanical interface, mounting geometry, and electrical characteristics, ensuring complete compatibility. This approach is specifically designed to resolve sourcing challenges or situations where the original model becomes difficult to obtain. Installation is straightforward, as the replacement fits directly without any adjustments, delivering a seamless functional match.
Since this customized solution was introduced, it has been widely adopted by customers across multiple international markets. Users from regions such as the Middle East, Russia, Indonesia, Brazil, Southeast Asia, and Ukraine have successfully applied these tailor-made units in demanding industrial environments. The combination of reliable performance and a 15-working-day production timeline has made the offering especially attractive for clients seeking both precision and timely delivery.
