Genuine Dell OEM Fingerprint Reader Ribbon Cable

This is a genuine Dell OEM ribbon cable that connects the fingerprint reader module to the power button board inside the Inspiron 15 7577 laptop. It carries part number CKF5C and is supplied new in the exact condition pictured. Buyers who need a replacement for a damaged or missing original cable will find the correct OEM fit here.

Replaces the Original Factory Cable CKF5C

The cable replaces the factory-installed ribbon identified by Dell part numbers CKF5C, CKF50 and NBX00027K000. It is the direct swap when the existing flex has torn, creased or lost continuity after a hinge repair or liquid spill. The jump is worth it only for owners of the Inspiron 15 7577 model; all other laptops use a different flex layout and connector pitch.

Restores Biometric Login Under Daily Use

Once installed, the flex restores the electrical path between the reader sensor and the power button controller so Windows Hello recognises a finger press on every boot. The thin polyimide construction tolerates the repeated hinge flexing that occurs when the lid opens and closes throughout a normal working day. Buyers who want a second fingerprint reader or an upgraded sensor module cannot use this cable because it is keyed to the original single reader design.
