We offer an OEM-grade rotary encoder solution for the CRF66-4096G4096E13, engineered to precisely replicate the original SSI absolute encoder in both performance and physical design. The replacement maintains the same 4096×4096 multi-turn resolution, SSI communication characteristics, and complete mechanical interface. Shaft configuration, flange size, housing dimensions, and electrical parameters are reproduced in full, allowing direct installation without mechanical rework, parameter changes, or control system adjustments. The standard production cycle is approximately 10 working days, supporting fast response to maintenance or retrofit requirements.
This OEM encoder solution has been supplied to industrial users in Russia, Southeast Asia, the Middle East, Brazil, and Ukraine. It is well regarded for stable SSI output, accurate multi-turn position feedback, and durable construction in harsh operating environments. Designed for long-term reliability, it performs consistently in industrial automation systems, lifting and hoisting equipment, CNC machinery, and other applications where precise absolute positioning and dependable operation are essential.
