We provide an OEM encoder replacement for the CRF65-4096G4096E03, engineered to fully match the original SSI absolute encoder in both electrical performance and mechanical structure. The encoder maintains the same 4096×4096 multi-turn resolution, SSI communication protocol, and timing characteristics. All physical parameters—including housing dimensions, shaft configuration, sealing level, and connector orientation—are precisely reproduced, enabling direct installation without parameter changes or system modifications. The standard production lead time is 10 working days, supporting fast maintenance and stable supply.
Designed for precision automation environments, this OEM encoder delivers stable and accurate absolute position feedback under continuous duty cycles. Optimized internal signal processing ensures reliable SSI data transmission, even over long cable distances, while the robust sensing structure guarantees consistent multi-turn tracking during frequent start-stop operations. It is well suited for machine tools, heavy conveyors, industrial lifting systems, and synchronized multi-axis equipment, offering long-term reliability and dependable performance in demanding industrial conditions.
