For the CRF58-4096G4096E10, we provide a dedicated absolute encoder replacement solution engineered to match the original SSI encoder on a true custom-fit basis. All essential parameters—including mounting dimensions, shaft interface, SSI protocol configuration, resolution profile, and electrical characteristics—are precisely reproduced to align with the existing system architecture. This allows the replacement to be installed and commissioned immediately, without rewiring, mechanical modification, or controller reconfiguration. It is particularly well suited for equipment refurbishment, discontinued-model substitution, and long-term maintenance planning where configuration stability is critical.
This replacement solution has been successfully delivered to customers in Russia, the Middle East, Indonesia, Ukraine, and South America. Users recognize its stable signal performance, reliable absolute positioning accuracy, and strong cost-effectiveness. With a predictable production lead time of around 15 working days, it offers a dependable option for industrial applications that demand consistent absolute feedback and long service life under continuous operation.
