The FANUC A86L-0001-0235 is a rectangular 44-key keyboard PCB installed behind the key membrane of compatible FANUC CRT/MDI operator panels. It converts manual key selections into input signals for CNC program editing, parameter entry, screen navigation and machine operation.

This keyboard is also identified by the Fujitsu number N860-3755-T901, with N86D-3755-R001 commonly marked on the board. It is a replacement keyboard assembly, not a complete CRT/MDI unit, monitor or front membrane.

A86L-0001-0235 Product Information

CRT/MDI Keyboard Function

The A86L-0001-0235 provides the physical key-switch interface beneath the operator-panel membrane. It supports data entry and control selections used by the CNC interface. A failed board may cause individual keys, key groups or the complete keyboard to stop responding even when the display remains operational.

Compatibility and Nameplate Checks

Do not select this part from the CNC series alone. Compare A86L-0001-0235, N860-3755-T901, the N86D board revision, connector position, PCB outline, key count and front-membrane layout with the removed unit. A02B-0210-C041 is a documented panel application, but its /M, /T and other suffixes identify different operator-panel configurations.

Testing and Installation Notes

REACO CNC checks the PCB condition, connectors, key matrix and key response before shipment. Disconnect machine power before opening the operator panel, use ESD protection and avoid folding or damaging the membrane tail. Confirm whether the quotation covers the keyboard PCB only or includes the membrane, bezel or complete MDI panel.
