Fanuc CAP i T Keyboard for 16i/ 18i/ 21i A02B-0281-C126#TFBS

📌 Part Overview

A02B-0281-C126#TFBS is a symbolic CAPi-T vertical separate-type MDI (Manual Data Input) unit used on CNC machine operator control panels. It’s part of the A02B-0281 series of standalone input/keypad modules for FANUC CNC controls.

• Part Number: A02B-0281-C126#TFBS

• Manufacturer: FANUC

• Series: A02B-0281 (MDI/input modules for FANUC CNC systems)

• Type: Separate-type MDI unit — a dedicated manual data input keypad without an integrated display.

• Orientation: Vertical mount — designed to be installed upright on the operator console.

• Keyboard Layout: Symbolic CAPi-T layout — uses symbols on keys instead of plain text, suitable for standardized CNC interfaces in multi-language environments.

📌 Functionality

This unit serves as a manual operator input interface, letting personnel manually enter:

• Program numbers

• CNC commands

• Parameters and numeric values

• Menu navigation and selection inputs

It does not include a display screen — it works as the keypad/input part of an operator interface alongside a separate display unit on the control panel.

📍 Typical Use

• Installed on FANUC CNC machine control panels that use a stand-alone MDI keypad rather than an integrated display/keyboard.

• Often used in older or legacy CNC controls that require a dedicated manual input device.

📍 Notes

• This is generally a legacy industrial part and is often sourced as refurbished, surplus, or new-old-stock because many modern CNC systems now use integrated key/display panels.

• Matching the “#TFBS” suffix is important to ensure you get the vertical orientation with the symbolic CAPi-T keyboard layout expected for your panel.
