More Information

Overview Manuals Key Matrix Assembly Layers Panel Fit Identification

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.
Description
Fanuc A86L-0001-0235 is a 44-key CRT/MDI keyboard assembly for operator data entry at a CNC control panel. The key matrix converts individual key presses into the electrical states read by the control-side keyboard interface.

Beneath the key surface, A86L-0001-0235 combines the membrane contacts with a printed circuit board marked N86D-3755-R001/01. That board distributes each switch position into the matrix instead of assigning a separate cable conductor to every key.

The mechanical outline of A86L-0001-0235 fixes the key spacing, board mounting points, and panel fit as one assembly. Matching the complete A86L number together with the board marking avoids confusing a similar-looking Fanuc keypad with the required keyboard layout.

Technical notes
Fanuc A86L-0001-0235 should be matched by the complete A86L code and the N86D-3755-R001/01 board marking before panel replacement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which markings should be compared before ordering Fanuc A86L-0001-0235?
Compare the complete Fanuc A86L-0001-0235 code with the N86D-3755-R001/01 marking on the keyboard board. Using both identifiers reduces the risk of selecting a visually similar keypad with a different matrix or mounting pattern.
Why does a key on Fanuc A86L-0001-0235 need matrix-level diagnosis?
Each Fanuc A86L-0001-0235 key closes one position in a shared row-and-column matrix. If several keys in one row or column fail together, inspect the common membrane path and connector before assuming several independent switches failed.
What should be preserved when transferring Fanuc A86L-0001-0235 to another panel?
Keep the Fanuc A86L-0001-0235 board orientation, mounting points, membrane alignment, and connector direction unchanged. A rotated or offset matrix can produce incorrect key mapping even when the assembly physically fits.
How can Fanuc A86L-0001-0235 be checked before the CNC is returned to operation?
After installing Fanuc A86L-0001-0235, test every key in the control's approved input screen and confirm that each press produces the expected symbol or command. Do not validate the keyboard from only a few numeric keys.
Why is the 44-key count important for Fanuc A86L-0001-0235 selection?
The 44-key layout is part of the Fanuc A86L-0001-0235 assembly identity because it determines both the operator legends and the electrical matrix. A keyboard with a different key count cannot be assumed to share the same mapping.
