Right-angle mounting orients the pins parallel to the board edge, suited for mezzanine or perpendicular board-to-board stacking where the mating receptacle sits on a daughtercard. The unshrouded design means no polarization keying — orientation is set by the board layout, and the header accepts a standard BergStik receptacle housing from either direction. ## Key ratings and what they mean for the fit Rated 5A per contact with gold or GXT™ plating at 30.0µin (0.76µm) minimum on the mating surface. That plating thickness supports repeated mating cycles without exposing the phosphor bronze base metal — the header holds up in assemblies that see periodic board swaps or field rework. The 110V voltage rating and UL94 V-0 housing satisfy the flame and dielectric requirements for equipment inside an enclosure. The 0.318\" (8.08mm) mating pin length provides enough reach to engage a standard receptacle housing seated on the mating board.","metaTitle":"FCI 86840-120HLF BergStik II Header, 20 Pos, 0.100\" Pitch","metaDescription":"FCI 86840-120HLF BergStik II unshrouded header, 20 positions, 0.100\" pitch, 5A, gold/GXT plating.
