The Amphenol 93939-138HLF is a 38-position, dual-row BERGSTIK® II unshrouded header with a 0.100" (2.54 mm) pitch on both rows and between rows.
For a 38-position dual-row header, the total current through the connector depends on how many circuits carry load simultaneously; the 5A figure is a per-contact maximum, not a sum across all 38 positions. The 110V voltage rating is conservative for signal-level board interconnects but adequate for low-voltage power distribution within an enclosure. The 0.100" pitch and 0.100" row spacing give a standard footprint that matches legacy BergStik and many other 2.54 mm grid headers. The 0.190" (4.83 mm) insulation height and 0.160" (4.06 mm) mating pin length give enough standoff for most standard shrouded receptacles.
Mating and sourcing
The 38-position count is fully loaded (all positions populated), so the BOM line must match exactly; there is no option to depopulate positions on this variant.
