Genuine Dell OEM Palmrest USH Ribbon Cable 1F3FR

This genuine Dell OEM ribbon cable connects the palmrest junction board to the motherboard on Latitude 5289 2-in-1 and Latitude 7390 2-in-1 laptops. It restores the USH fingerprint reader or security module connection when the original cable is damaged.

Verify your exact 2-in-1 model before ordering

Confirm the service tag matches Latitude 5289 2-in-1 or Latitude 7390 2-in-1, as this cable is not compatible with standard clamshell variants. Check the existing cable part number against 1F3FR, CAZ40 or NBX00023400 to ensure the correct fit.

Thin flexible circuit with model-specific connectors

The flat ribbon design routes through the tight hinge area of the 2-in-1 chassis, so handle it carefully during installation to avoid creasing. The keyed connectors on each end seat directly into the palmrest board and motherboard sockets without additional hardware.

Questions about this item

Does the package include only the palmrest USH ribbon cable with part number 1F3FR, or are any screws or brackets also supplied?

You will receive exactly the ribbon cable shown; no screws, brackets or additional hardware are included.

My laptop is a Latitude 5289 2-in-1 — will the alternate part numbers CAZ40 and NBX00023400 fit the same way as 1F3FR?

Yes, CAZ40 and NBX00023400 are alternate Dell part numbers for the same palmrest USH ribbon cable used in the Latitude 5289 2-in-1 and 7390 2-in-1.

After fitting this cable, will the fingerprint reader and power button on the palmrest work without further configuration?

The cable restores the electrical link between the palmrest junction board and the motherboard, so the fingerprint reader and power button function once the cable is seated correctly.
