DELL Inspiron 7490 Fingerprint Reader Ribbon Cable 27X61

Dell Inspiron 7490 Fingerprint Ribbon Cable

This genuine Dell OEM ribbon cable connects the fingerprint reader junction board to the motherboard inside an Inspiron 7490 laptop. It carries the part number 27X61 and matches the alternate references EDW40, NBX0002IV00 and NBX00021V00. The component is supplied new and is intended for technicians repairing or restoring the biometric login function on that specific model.

Verify Inspiron 7490 Model and Connector Layout

Before ordering, confirm the laptop is an Inspiron 7490 and that the fingerprint reader assembly uses a ribbon cable with the same connector orientation and pin count as the original. The cable routes between the reader board and the mainboard, so inspect the existing flex for damage, creasing or corrosion on the contact pads. Ensure the replacement part number 27X61 appears in the service manual for your exact chassis configuration.

Sustained Use Maintains Signal Integrity

Under continuous daily operation the cable maintains a stable connection between the sensor and the motherboard without signal degradation. The flex construction resists fatigue from repeated lid cycles and normal thermal expansion inside the chassis. No active cooling or power management is required; the passive link simply preserves the authentication path for as long as the laptop remains in service.
