The AMS40K-1312 SSI absolute encoder can be provided as a 1:1 customized replacement solution, with a standard production lead time of 10 working days. Our replacement model is designed to precisely match the original encoder’s mechanical dimensions, shaft configuration, and SSI communication interface, ensuring direct electrical and mechanical compatibility. This plug-and-play solution allows users to install the replacement encoder effortlessly without modifying system wiring or control parameters.
From a technical standpoint, the AMS40K-1312 encoder delivers high-resolution absolute position feedback and stable SSI signal transmission, making it suitable for heavy-duty industrial applications such as steel processing, paper manufacturing, and large-scale automation systems. Its rugged construction and precision engineering ensure exceptional performance and reliability, even under conditions of high vibration and temperature variation. Our replacement encoders have been successfully deployed in South America, Southeast Asia, the Middle East, Indonesia, and Russia, where they are recognized for their durability and long-term stability.
