What this cover does in the assembly
The 5017848009 is a protective cover for a 0.5mm pitch FFC plug, holding 80 positions. It snaps over the plug body after the FFC is inserted, providing strain relief and preventing the cable from backing out during handling or vibration. This cover is designed for the Molex 501786 and 501864 series FFC plugs. If your BOM calls for either of those plug bodies, this is the matching cover — order it alongside the plug and terminals to complete the assembly.
Mating and compatibility checklist
Mates with 501786 and 501864 series FFC plugs. The cover is not a connector body — it does not carry current or provide contacts. It is a secondary retention piece that clips onto the plug after the FFC is terminated. The 80-position count matches the plug's circuit density. Confirm your FFC has the same number of conductors and a 0.5mm pitch before ordering.
