We provide a 1:1 replacement solution for the AMG81P13Z0 absolute encoder, engineered to match the original unit’s electrical interface, signal behavior, and mechanical mounting. This replacement is designed for easy integration into existing Profibus‑DP or SSI control systems without changes to PLC programs, network settings, or motion profiles, making it suitable for retrofit projects and maintenance spares.
The AMG81P13Z0 encoder delivers optical absolute position feedback with high resolution and stability, supporting precise single‑turn measurement. It operates on a 10–30 V DC supply with reverse polarity protection and features programmable parameters such as code sequencing (CW/CCW) and rotational direction to align with existing control logic. Integrated diagnostic functions and the DUO‑LED status indicator provide clear operational feedback and fault reporting for improved system reliability.
Mechanically, this replacement preserves the original encoder’s flange and shaft interface dimensions, ensuring direct compatibility with existing mounts and drive systems. The design meets industrial interference immunity and emissions standards, providing stable signal output in electrically noisy environments.


This 1:1 replacement solution offers consistent absolute feedback performance, reliable diagnostics, and straightforward installation for applications requiring dependable position feedback without system reconfiguration.
