For the CRF65-4096G4096E15, we provide a fully custom absolute encoder replacement engineered to match the original SSI encoder on a true 1:1 basis. The solution preserves the same multi-turn resolution structure, SSI communication behavior, and complete mechanical interface, including housing dimensions, shaft configuration, and mounting details. By maintaining full electrical and mechanical consistency, the replacement can be installed directly without parameter changes, rewiring, or control-system adjustments, effectively resolving issues related to discontinued models or extended procurement cycles.
This custom replacement has been successfully delivered to users in Russia, Indonesia, the Middle East, Brazil, Southeast Asia, and Ukraine. Customers value its stable absolute feedback, durable mechanical design, and predictable production lead time of approximately 15 working days. Designed for long-term operation in demanding industrial environments, it performs reliably in applications such as automation systems, lifting equipment, CNC machinery, and energy-related installations where accurate and continuous absolute position feedback is essential.
