Genuine Dell OEM Fingerprint Reader Cable

This is a genuine Dell OEM fingerprint reader module circuit board with cable designed for the Dell Latitude E6420 laptop. It arrives exactly as pictured and carries Dell part numbers PAL50, NBX0000T90L, PK090009D2L and VAL1110. The part restores biometric login functionality on the specified model.

Replaces a faulty or missing fingerprint reader

Install this cable when the original reader fails or has been removed during a previous repair.

Buyers who need a different laptop model or a complete palm-rest unit should look elsewhere.

Questions about this item

Will this fingerprint reader cable fit inside a Dell Latitude E6420 chassis?

Yes, it is a genuine Dell OEM part made specifically for the Latitude E6420 and matches the part numbers PAL50, NBX0000T90L, PK090009D2L and VAL1110.

What is the tricky step when installing this fingerprint reader module cable?

The flat ribbon cable must be fully seated in the ZIF connector on the system board before the locking flap is closed; a partial insert will leave the reader undetected.
