FANUC A02B series is the classic CRT/MDI operator panel series for FANUC old-generation CNC systems. Among the series, model A02B-0120-C051 is a 9-inch monochrome CRT display plus MDI membrane keyboard integrated unit, specially designed for FANUC 16-M CNC controller system, commonly installed on vertical machining centers, milling machines and mold processing equipment.

This integrated panel serves as the core human-machine interface of the CNC machine tool. Operators can directly complete multiple daily operation tasks on the panel: edit and modify NC machining programs, set workpiece coordinate offsets and tool compensation values, adjust system parameters, select automatic, single block or manual operation mode. Meanwhile, the screen displays real-time axis coordinate position, spindle rotating speed, feed rate, program running status and system alarm text messages. When machine fault occurs, alarm information can guide maintenance technicians to quickly locate the root cause of failure.

The A02B-0120-C051 panel adopts a sturdy metal outer casing. Internal circuit boards use anti-vibration and anti-electromagnetic interference design. The membrane keypad is wear-resistant to cope with frequent pressing operation in noisy machine workshop environment. It connects to FANUC CNC main unit through dedicated signal and power connectors, realizing stable video signal transmission and data communication.

This model has been officially discontinued by FANUC, and new original factory production is no longer available. However, a large quantity of machining centers equipped with FANUC 16-M system are still operating in mechanical factories around the world. We stock fully tested original A02B-0120-C051 spare parts. It supports direct swap replacement. After installation, operators can restore all HMI functions of the machine tool, without modifying the original CNC control program and machine wiring.
