FANUC 31-B SOFTKEY 12-key membrane keyboard kit for 31i CNC console - LOW version

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 e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This FANUC membrane keysheet is a 12-key softkey kit for Series 31i operator panels. It restores reliable HMI input at the console and replaces worn or unresponsive softkeys on 31-B panels. 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.

Designed for the 31i console low version, this 12-key membrane aligns with the on-screen menu keys to ensure precise operator interaction without altering panel electronics. It supports typical FANUC HMI signal routing through the existing keyboard PCB, which keeps the original wiring and console layout intact and avoids software changes during field replacement.

In day-to-day machining environments, softkeys see heavy use and can become stiff, intermittent or lose legends. This kit restores a clean, responsive front interface for FANUC 31i-B controls with the horizontal softkey row under the screen. The sealed front surface helps with routine wipe-down on the production floor and maintains clear key labels for operators.

The kit suits a wide range of machine tools built around FANUC 31i controls, including turning centers and machining centers that use the horizontal softkey configuration. It is a straightforward drop-in on compatible consoles that already use the 12-key horizontal layout beneath the LCD, which makes it practical for planned maintenance and quick field replacement.

Maintenance teams commonly fit this kit when operators report missed key presses, cracked overlays or faded markings. Keeping a stocked spare on site shortens downtime and supports preventive maintenance schedules, especially on busy 31i-based machines. As a drop-in replacement that uses the existing HMI PCB, it helps restore machine operation quickly without rework to wiring or parameters.

Each unit is checked on appropriate CNC HMI test benches and simulators by skilled engineers to verify key response and continuity before dispatch. Units are packed flat with protective materials to prevent creasing during transport. Standard warranty terms apply, and worldwide shipping is available through our industrial logistics partners.

For older or obsolete 31i panel variants, this kit can serve as an emergency spare to reduce unexpected downtime. Cnc-shopping can assist with sourcing hard-to-find FANUC HMI parts, and repair or exchange service options may be available to support long-term machine uptime on legacy installations.

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

How do I confirm it fits my panel layout
This kit is for the horizontal low version layout on FANUC 31i-B consoles, where 12 softkeys sit directly under the LCD. If your console has vertical softkeys or a different key count, request the matching variant before ordering.

Does this kit require parameter changes
No changes are typically required. It replaces the front membrane on a compatible 31i operator panel and works with the existing HMI PCB and wiring.

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

Can this be used as a preventive spare
Yes, many MRO teams keep one in industrial spare inventory to cover sudden softkey failures and reduce machine downtime during high-load production periods.
