DELL Latitude 7280 7380 7290 7390 Palmrest USH Ribbon Cable 5XG64

Genuine Dell Palmrest Junction Board Ribbon Cable

This genuine Dell OEM ribbon cable connects the palmrest junction board to the motherboard on compatible Latitude laptops. It is designed for technicians or owners repairing a damaged or faulty flex connection. The part restores the link between the palmrest assembly and the main board. It fits Latitude 7280, 7380, 7290 and 7390 models.

Thin Flex Cable Routing Constraints

The ribbon is a thin flexible circuit that must follow the original chassis path inside the laptop. Sharp bends or pinching during reassembly can sever conductors and cause intermittent faults. Installers must keep the cable flat and avoid stretching it beyond its natural length. No alternative routing is possible within the existing hinge and frame design.

OEM Build Quality and Connector Fit

Genuine Dell construction matches the original factory specification for connector pitch and retention force. The ends seat directly into the motherboard and palmrest board sockets without adapters. Correct alignment prevents damage to the delicate ZIF or board-to-board contacts. This part is not intended for models outside the listed Latitude series.
