We offer a customized replacement solution for the AMG11S25T1024, developed for systems that rely on the SSI communication interface for precise and stable position feedback. With a resolution of 1024 steps per revolution, this encoder is well suited for industrial applications where accurate absolute position information and reliable signal transmission are essential.
The encoder is based on optical sensing technology, ensuring consistent accuracy and repeatability over long operating periods. The SSI interface provides deterministic data output and strong resistance to electrical interference, which is particularly important in electrically noisy environments such as motor drives, automation equipment, and material handling systems. Its mechanical design supports continuous operation and maintains performance under vibration and shock commonly found in industrial installations.


This customized replacement is engineered to match the original encoder’s electrical characteristics and functional behavior, while allowing controlled customization of mechanical details to suit specific installation requirements. Each unit is reviewed and verified by our engineering team prior to production to ensure compatibility with existing systems. By selecting this solution, customers gain a reliable alternative with predictable lead times, long-term supply security, and professional technical support, without the need for software or control system changes.
