Product Information

Product Application

The FANUC A20B-9000-0300 sensor module is mainly used for compatible FANUC AC spindle motor applications. It may be required when the original spindle motor sensor module is damaged, unstable, contaminated, corroded, or causing spindle feedback, speed detection, rotation detection, orientation, or sensor-related alarm problems.

If your AC spindle motor has unstable speed feedback, spindle orientation failure, feedback signal loss, sensor alarm, or abnormal spindle operation, this sensor module may be considered as a replacement after confirming the full sensor model, spindle motor model, connector layout, spindle amplifier model, and CNC system compatibility.

Quality Control and Testing

For FANUC AC spindle motor sensor modules, careful checking is very important before shipment because sensor condition may directly affect spindle feedback, speed detection, spindle orientation, motor control stability, and CNC machine operation. REACO CNC checks qualified products carefully and can provide real product photos or a test video before delivery when required.

Our goal is to help customers receive reliable FANUC CNC spare parts with clear product information, careful inspection, responsive after-sales support, and practical technical assistance.

Compatibility Confirmation

Before ordering, please confirm that the full sensor module number on your original part is A20B-9000-0300. Similar FANUC spindle motor sensor modules may have different connector layouts, motor compatibility, sensor specifications, mounting structures, or spindle system requirements.

If you are not sure whether this FANUC sensor module is suitable for your AC spindle motor, please send photos of the original sensor label, spindle motor nameplate, connector photos, spindle amplifier model, CNC system model, and alarm information. REACO CNC can help check the details before purchase.
