FANUC 31-B SOFTKEY 12-key membrane keyboard kit for 31i CNC console - Horizontal model

Buy online your FANUC 31-B SOFTKEY 12-key membrane keyboard kit for 31i CNC console - LOW version reference 31-B/12-key from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This FANUC keysheet is a 12-key softkey overlay for Series 31i-B low version operator panels. It restores the front HMI interface on CNC consoles that use the horizontal softkey row under the monitor, replacing worn or unresponsive membranes without altering the panel electronics. The kit is for the HORIZONTAL model, where the softkeys are located below the FANUC LCD monitor on the CNC controller, and is used as a replacement unit or CNC replacement component for maintenance and rebuild work.

In the CNC architecture this membrane sits on the operator panel face and transfers operator input to the existing keyboard PCB. The alignment matches the on-screen softkey labels on 31i-B, so menu navigation and confirmation keys line up correctly. No parameter edits are expected during a field swap because wiring and the underlying PCB remain original.

The 12-key horizontal layout suits turning centers and machining centers that run FANUC 31i-B consoles in the low version format with softkeys beneath the LCD. The sealed front surface supports routine wipe-down on the production floor and keeps legends readable for operators who use these keys all day.

Typical failure signs include missed presses, stiff travel or faded markings. This drop-in replacement brings the console back to a clean, responsive state and is practical for planned maintenance or a quick change during downtime. Manufactured in Japan, it maintains original fit and feel on compatible 31i-B horizontal panels.

Manufacturer: FANUC

Product type: FANUC Membrane keysheet

Main function: 12-key softkey front interface for FANUC 31i-B operator panels with a horizontal row beneath the LCD

Key technical data: 12-key membrane kit for Series 31i console low version, horizontal softkeys positioned below the screen, uses the existing keyboard PCB and wiring, manufactured in Japan, supplied as a service kit for operator panel refurbishment, fast dispatch typically within 3 days depending on availability. Many stocked items ship directly from our Florida facility.

Maintenance teams install this unit when operators report intermittent keys, cracked overlays or unreadable legends. Keeping a spare part on site shortens machine downtime and fits well into preventive schedules on busy 31i-based machines. As a drop-in replacement that reuses the installed PCB, it helps recover machine operation without panel rework.

Each tested unit is verified on appropriate CNC HMI test benches by skilled engineers to confirm key response and continuity. Units ship flat with protective packaging that prevents creasing during transport. Standard warranty applies. Depending on availability, products are commonly dispatched from our Florida warehouse.

For older or obsolete 31i panel variants this kit can serve as an emergency spare to limit unexpected downtime. Cnc-shopping USA supports sourcing of hard-to-find FANUC HMI parts, and repair service or exchange service options may be available to keep legacy machines running.

Frequently asked questions about 31-B/12-key:

How can I confirm compatibility with my 31i panel
Count the softkeys and check placement. This kit fits the 12-key horizontal low version where the softkeys sit directly under the LCD on 31i-B consoles. If your panel has vertical keys or a different count, request the matching variant before ordering.

Are parameter or wiring changes required after installation
No changes are typically needed. The membrane replaces the front overlay and works with the existing HMI keyboard PCB and original wiring.

What is included in the kit
It includes the 12-key membrane assembly for the 31i-B horizontal layout. The keyboard PCB, LCD, bezel and other panel hardware are not included.

Is this suitable to keep in industrial spare inventory
Yes, many MRO teams hold one as a replacement unit to cover sudden failures and to support quick field replacement during high-load production periods.
