We provide a custom replacement solution for XHI 803 770594-01, engineered to match the original incremental encoder in mechanical design, electrical characteristics, and signal behavior. This replacement is intended for maintenance, retrofit, and long-term supply continuity scenarios where the original model is difficult to source. The solution is developed based on application requirements and can be adapted to shaft interface, mounting dimensions, output format, and resolution to ensure seamless integration into existing systems without changes to the control logic.
The encoder is designed for heavy-duty industrial applications, offering stable incremental output signals suitable for speed feedback and relative position measurement. It supports common incremental signal formats with reference pulse options and is compatible with standard PLCs, drives, and motion controllers. The robust housing and bearing structure enable reliable operation under vibration, shock, and varying environmental conditions, making it suitable for cranes, conveyors, steel processing, and other demanding automation equipment.


This custom replacement focuses on functional equivalence rather than brand dependence, ensuring consistent performance and long-term availability. Each unit is technically reviewed before production to confirm key parameters such as resolution, output level, supply voltage, and mechanical interface. By choosing this replacement for XHI 803 770594-01, users gain a reliable, application-oriented solution backed by engineering support, controlled lead time, and stable supply for future maintenance needs.
