Genuine Dell OEM fingerprint ribbon cable

This genuine Dell OEM ribbon cable connects the fingerprint reader module to the system board on Latitude 5289 and 7390 2-in-1 laptops. It carries the Dell part number CAZ40 and alternates NBX00023300 and NBX00023V00. The component is supplied new and matches the part shown in the listing images.

The flexible cable routes within the convertible hinge area to link the biometric sensor to the mainboard. Installing it restores fingerprint authentication without requiring a full top-case assembly. No additional adapters or daughter boards are needed for the connection.

Replaces a damaged or worn original ribbon cable

Swap this part when the fingerprint reader stops being recognised after hinge stress or liquid exposure. The upgrade is worthwhile when diagnostics show an open circuit on the sensor path and the reader module itself tests functional. It does not add fingerprint capability to models that never shipped with the sensor.
