GM401.010A002 and GM401.A10A002 SSI Encoder 1:1 Replacement

We provide a reliable SSI encoder 1:1 replacement solution for the GM401.010A002 and GM401.A10A002 models, developed for direct use in absolute multiturn positioning systems. This replacement is engineered to match the original encoder in interface behavior and functional logic, allowing installation without changes to controller configuration, wiring, or software parameters.

The encoder operates with a Synchronous Serial Interface and delivers high-resolution absolute position feedback across both singleturn and multiturn ranges. Stable data transmission and consistent signal timing ensure accurate position information even in applications with frequent speed changes or continuous operation. Support for standard code formats enables compatibility with a wide range of industrial control platforms.

From a mechanical standpoint, the design aligns with established industrial mounting standards, enabling straightforward installation on existing shafts. The internal architecture incorporates continuous self-diagnostic monitoring, including checks for code stability, signal frequency limits, and internal electronic status. These features improve operational reliability and support predictive maintenance strategies.

This 1:1 replacement is suitable for servo drives, automated production equipment, and industrial machinery where precise absolute feedback and long-term stability are essential.
