Features:
- Forty-four keys provide CNC operator data and command entry
- Membrane contacts feed a shared keyboard matrix on the PCB
- N86D-3755-R001/01 board marking supports exact assembly matching
Each key closes one row-and-column intersection, allowing the control interface to distinguish operator commands through a compact matrix connection.
The membrane, printed circuit board, and mounting outline work as one keyboard assembly; changing only one layer can alter alignment or key response.
The A86L order code and the board marking provide separate checks for the external keypad identity and the internal electronics.
The Fanuc A86L-0001-0235 44-Key CRT/MDI Keyboard Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How operator keys become control inputs
- Matrix layout: Forty-four switch positions are arranged as a row-and-column matrix.
- Switch action: A key press joins one row to one column instead of using a dedicated wire pair.
- Control reading: The CNC keyboard interface reads the resulting matrix state as a command.
Membrane and PCB relationship
- Key surface: The key surface transfers force to the membrane contacts.
- Membrane: The membrane closes the selected matrix position on the printed circuit board.
- Circuit board: Board and membrane alignment determines whether each legend maps to the intended circuit.
Mechanical points that define the keyboard
- Board outline: The keyboard outline fixes the mounting-hole pattern in the operator panel.
- Mounting points: Connector direction must remain consistent with the receiving control panel.
- Connector direction: The 44-key layout must match the panel opening and legend arrangement.
Two references for exact matching
- Order code: A86L-0001-0235 identifies the complete Fanuc keyboard assembly.
- Board marking: N86D-3755-R001/01 identifies the observed printed circuit board.
- Combined match: Both references should agree before a similar keypad is accepted.
