For the CRF65-4096G4096E12, we supply a precisely engineered SSI encoder replacement model developed on a true 1:1 basis. The design fully replicates the original encoder’s 4096×4096 absolute resolution, SSI communication behavior, and mechanical structure. Through non-standard customization, all critical parameters—including mounting dimensions, shaft configuration, housing geometry, and SSI protocol timing—are preserved, allowing direct plug-and-play installation without any changes to control logic or mechanical interfaces. This replacement is well suited for scenarios involving discontinued models, long lead times, or urgent equipment downtime.
The solution has been successfully adopted by users in the Middle East, Indonesia, Brazil, Russia, Southeast Asia, and Eastern Europe. Customers value its stable signal output, reliable multi-turn tracking, and consistent performance under continuous industrial operation. With a predictable production cycle of approximately 15 working days, it provides a dependable and cost-effective option for long-term equipment maintenance and system continuity.
