The FANUC A02B-0323-C120#M is a small-type, horizontal Manual Data Input (MDI) unit for CNC milling applications. It provides the operator keyboard used to enter and edit programs, parameters, offsets and other numerical control data from the machine panel.

The complete suffix is important: #M identifies the milling version. A02B-0323-C120#T is the turning version and should not be treated as the same key layout. Use the full nameplate number when requesting a replacement.

CNC Manual Data Input Functions

This MDI unit gives the machine operator direct access to letters, numbers, cursor controls and editing commands required during CNC setup and operation. Typical replacement reasons include worn or unresponsive keys, damaged legends, intermittent input, connector damage or contamination.

Milling #M and Turning #T Versions

A02B-0323-C120#M is the milling configuration. Do not substitute A02B-0323-C120#T solely because the base number and panel size are similar. The suffix identifies the application-specific key arrangement. Other A02B-0323-C12x MDI units may also have different layouts, electronics or interfaces.

Compatibility, Testing and Installation

Confirm the complete A02B-0323-C120#M label, front key legends, rear PCB marking, connector, cable, mounting points and panel opening against the original unit. The published H 200 × W 140 mm notation should not be used as a mounting-cutout dimension unless confirmed by the machine documentation.

REACO CNC checks the housing, overlay, key response, connector condition and data-entry operation as applicable. Power down the CNC before removal, protect the electronics from static discharge and have installation completed by qualified personnel.
