We provide a 1:1 replacement solution for the AMG81S13Z0 absolute encoder, engineered to match the original unit’s electrical interface, signal output, and mechanical mounting dimensions. This replacement is designed for seamless integration into existing automation and motion control systems without requiring changes to PLC logic, bus parameters, or controller settings, making it suitable for maintenance spares, retrofit upgrades, and long‑term system support.
The AMG81S13Z0 encoder delivers optical absolute position feedback with reliable resolution and signal stability, providing accurate position data for closed‑loop control applications. It operates on a 10–30 V DC supply with reverse polarity protection and supports programmable options including CW/CCW code sequence and selectable rotational direction, allowing flexible alignment with existing control logic. Integrated diagnostics and the DUO‑LED status indicator provide instant visual feedback on operating status and fault conditions, helping to maintain system uptime.
Mechanically, this replacement preserves the original encoder’s flange and shaft interface, ensuring direct dimensional compatibility with existing mechanical mounts and couplings. The encoder design meets industrial standards for interference immunity and emissions, delivering consistent signal quality in electrically demanding environments.
This 1:1 replacement solution offers dependable absolute feedback performance, robust diagnostics, and straightforward installation with minimal configuration effort.
