Overall contact length is 0.736\" (18.69mm), with a 0.318\" mating pin length — this gives the mating socket enough wipe distance to establish contact without bottoming out. The unshrouded design means no polarisation key; the board layout must ensure the mating connector orientation is correct, as a 180° rotation will still mate but may misalign the circuit mapping. The base product number 68779 covers multiple plating and post-length variants; the -140HLF suffix specifies the 40-position, gold-plated, 0.318\" post configuration. ## Peer Comparison: 40 vs 36 Positions in the Same Series The board footprint grows by 0.400\" in length, while the current rating and gold plating remain identical. For a BOM that needs 40 signal lines, this part avoids a second connector and the associated harness split.","metaTitle":"68779-140HLF BERGSTIK II Header 40-Pos 2.54mm Pitch","metaDescription":"68779-140HLF Amphenol ICC BERGSTIK® II unshrouded header, 40 positions, 0.100\" pitch, 3A, 30µin gold.
