It carries male square pins with a 30.0 µ\" (0.76 µm) gold or Gold, GXT™ mating finish, rated for 5 A per contact at 110 V. The 0.100\" (2.54 mm) row spacing and 0.100\" pitch are the standard footprint for BergStik and compatible IDC socket strips — the PCB layout matches a generation of ribbon-cable and board-stacking receptacles. The unshrouded body means there is no keying ramp — the mating receptacle relies on board alignment, not connector polarization.","metaTitle":"Amphenol BERGSTIK II 79821-102HLF Header, 2-Pos","metaDescription":"Amphenol BERGSTIK II 79821-102HLF dual-row board-to-board header, 2 positions, 0.100\" pitch, 5 A, 110 V, 30 µ\" gold.
