We provide a fully customized OEM replacement for the CRF66-4096G4096E13, designed to replicate the original SSI absolute encoder’s 4096×4096 multi-turn resolution and mechanical dimensions with high precision. Every critical feature—including shaft interface, flange diameter, housing geometry, and SSI output parameters—has been carefully reproduced to allow direct installation without any adjustments. This solution addresses challenges in sourcing the original model and ensures uninterrupted operation in industrial systems. With a standard 10-working-day production cycle, it supports fast maintenance and timely upgrades.
This replacement encoder has been successfully delivered to users across Russia, the Middle East, Southeast Asia, Brazil, and Ukraine. Clients praise its reliable performance, accurate absolute feedback, and robust construction under demanding operating conditions. Its combination of mechanical compatibility, electrical consistency, and timely delivery has made it a trusted solution for industrial automation, lifting equipment, CNC machinery, and other critical applications requiring precise multi-turn position tracking.
