We offer a fully customized 1:1 replacement for the CRF58-4096G4096E27, designed to match the original SSI absolute encoder in every critical aspect. This engineered solution restores all mechanical dimensions, SSI communication parameters, resolution values, and electrical behavior, enabling seamless installation without modifying the user’s existing system. It is particularly suitable for customers who face sourcing difficulties or equipment downtime due to discontinued models. By reproducing the encoder’s structure and interface with high accuracy, the replacement ensures direct compatibility from the moment it is mounted.
Since introducing this replacement design, customers across the Middle East, Indonesia, Brazil, Russia, Southeast Asia, and Eastern Europe have provided strong feedback. Its stable performance, competitive cost level, and guaranteed 15-working-day production cycle make it a preferred option for both maintenance and large-scale industrial upgrades. The encoder delivers consistent reliability, even in demanding automation environments where precision and durability are essential.
