We provide a full 1:1 replacement for the ASS58I-F2AAAAHGN-0016 absolute encoder, which combines high accuracy and SSI communication for precise position monitoring. Its 58 mm housing and hollow shaft design enable direct, space-efficient mounting, while the hardware-based encoder structure guarantees fast and stable feedback without microcontroller delay. The unit’s optically isolated RS-422 interface ensures reliable data transmission even in electrically noisy industrial settings.
Our replacement encoder solutions have proven performance in industries such as steel, robotics, and petrochemicals. They are widely installed in Southeast Asia, Indonesia, the Middle East, and Russia, where users rely on their robust quality, repeatable accuracy, and global service support. This replacement provides a practical answer for companies seeking long-term availability and consistent performance.
