For the CRF58-4096G4096E26, we provide a precisely matched replacement model developed to fully replicate the original SSI absolute encoder in both mechanical structure and electronic interface. Through non-standard customization, all installation dimensions, SSI data format, and the 4096×4096 multi-turn resolution profile are reproduced, ensuring complete compatibility with existing systems. This replacement model is designed for users who need to maintain continuous operation when the original encoder faces long lead times or limited availability. The plug-and-play design allows direct installation without system modifications, reducing downtime and maintenance risk.
This replacement model has been successfully adopted by customers in Russia, the Middle East, Southeast Asia, Ukraine, and South America. Users value its stable SSI communication, accurate absolute position feedback, and reliable long-term performance under industrial conditions. With a controlled production cycle of approximately 15 working days, it provides a practical and cost-effective solution for machinery and automation systems that depend on precise and dependable absolute position control.
