What this connector is
The Amphenol FCI BERGSTIK II 68020-134HLF is a dual-row, 34-position unshrouded male header in the BERGSTIK II series, designed for board-to-board interconnects at 0.100" (2.54mm) pitch. Right-angle through-hole mounting with push-pull fastening keeps the footprint compact against the board edge while accepting a matching IDC or receptacle on the mating side.
Where it is used
BERGSTIK II headers at 2.54mm pitch are a default choice for board-to-board stacking in industrial automation, process control, and instrumentation — anywhere a reliable through-hole connection needs to survive repeated thermal cycles without a sealed connector. The unshrouded pin field accepts the matching IDC or friction-lock receptacle housing; the right-angle orientation routes the daughter card parallel to the parent board in a low-profile stack.
What the ratings mean for the fit
The 2.54mm pitch and dual-row layout match the industry-standard 0.100" header footprint — board layout tools will recognize the grid, and the 34-position count is large enough to matter for routing density on the inner rows. At 3 A per contact the header is suited for signal and moderate-power distribution; the gold plating grade (30 µin) supports repeated mating cycles better than tin, so this is a re-mateable interconnect, not a one-time factory assembly. The push-pull fastening is a friction-lock style — no jack-screw or clip, so the connection is not vibration-locked. In high-vibration environments a secondary board-level retention method or a shrouded variant should be specified.
