  • Matches part numbers AAZ50_FP_FFC and NBX0001TQ00

Genuine Dell OEM Fingerprint Reader Cable

This is a genuine Dell OEM ribbon cable designed for the Latitude E7270. It connects the fingerprint reader module to the USH junction board. The part restores biometric login functionality on compatible laptops. Buyers needing a different connector layout or a cable for another laptop model cannot use this part.

Passive Flex Cable With No Power Draw

The ribbon cable is a passive flexible circuit carrying only low-voltage signals. It draws no power and generates no heat during normal operation. There are no moving parts, fans or active electronics to create noise. Installation simply routes the flat cable through the existing chassis path.

Stable Signal Path Under Continuous Use

The cable maintains a reliable connection between the reader and the board during sustained fingerprint scans. Signal integrity does not degrade with repeated daily authentication cycles. Physical durability depends on correct routing without sharp bends or pinch points. Damage from crushing or liquid exposure is not covered by the cable design.

Questions about this item

How do I install the fingerprint reader ribbon cable on my Latitude E7270, and which step is most often done incorrectly?

Open the chassis, disconnect the old cable from the USH junction board, route the new AAZ50_FP_FFC cable along the same path, and seat both connectors fully; the step most often missed is pressing the ZIF latch until it clicks on the USH board side.

What maintenance or replacement will the AAZ50_FP_FFC ribbon cable need over time?

The cable itself requires no scheduled maintenance; if the fingerprint reader stops being recognised, reseat both ends of the AAZ50_FP_FFC cable first, and replace the cable only if the conductors or latch are physically damaged.

What is the first limit that appears when the fingerprint reader cable is used continuously?

Repeated flexing at the hinge area can fatigue the AAZ50_FP_FFC conductors, leading to intermittent fingerprint reads before any other component fails.
