Description
๐ Part Overview
A02B-0281-C125#TFBS is a symbolic CAPi-T horizontal separate-type MDI (Manual Data Input) unit used on industrial CNC operator control panels. Itโs part of the A02B-0281 series of standalone input/keypad modules designed for use with FANUC CNC controls.
๐ What It Is
-
Part Number: A02B-0281-C125#TFBS
-
Manufacturer: FANUC
-
Series: A02B-0281 (MDI/keypad units for FANUC controls)
-
Type: Separate-type MDI unit โ this is a manual data input keypad that connects to the CNC system, separate from the display unit.
-
Orientation: Horizontal mounting โ designed to mount flat in the control console.
-
Keyboard Layout: Symbolic CAPi-T layout โ keys are labeled with symbols (CAPi-T style) rather than plain English text, useful for machines with symbol-oriented interfaces.
๐ Function
This part functions as a manual operator input interface for a FANUC CNC system. Operators use it to enter:
-
Program numbers
-
Manual commands
-
Parameters and settings
-
Navigation inputs
It does not include a built-in display screen โ it acts as the keypad/input portion of an operator interface and is typically used with a separate display unit on the machineโs control panel.
๐ Notes
-
Itโs considered a legacy/stand-alone MDI component, often found as surplus, refurbished, or off-stock since many modern controls use integrated display/key panels.
-
Matching the #TFBS suffix ensures the symbolic CAPi-T keyboard layout and horizontal orientation are correct for your application.
