We provide a dedicated SSI absolute encoder replacement model for the CRF65-4096G4096E14, maintaining full consistency with the original technical specifications while ensuring stable lead times and controlled manufacturing quality. The mechanical envelope, mounting diameter, shaft type, and connector orientation are fully aligned with the original design. Electrical characteristics—including clock frequency tolerance, data word structure, and 4096×4096 multi-turn resolution—are preserved, allowing direct installation into existing systems without firmware or parameter adjustments. Standard production and delivery are completed within ten working days.
This replacement model is well suited for equipment requiring high-precision motion control and synchronized multi-axis positioning. An optimized sensing module improves interpolation stability, helping to reduce jitter under low-speed or high-load operating conditions. The SSI communication interface is designed for compatibility with mainstream PLCs and motion controllers, ensuring stable timing and reliable data transmission. It performs effectively in metal forming machinery, textile automation, robotic handling systems, and heavy conveyors, delivering consistent absolute position tracking and long-term durability in demanding industrial environments.
