Product details

Board-fit anchor: 0.100" pitch, 9 positions, single row

The 77311-118-09LF: That gold thickness supports repeated connect/disconnect cycles — useful for test fixtures or field-service boards where the header sees more than a few mates over its life.

Position count vs. siblings: 9 vs 8 vs 7

The 77311-118-09LF is the 9-position member of the BERGSTIK® single-row, unshrouded header family. The closest sibling is the 8-position 77311-118-08LF, identical in every other spec — same pitch, same plating, same current rating, same active lifecycle. If your BOM calls for 7 positions, the 77311-118-07LF is the drop-in alternative with the same footprint and ratings. No other functional difference exists across the 6-, 7-, 8-, and 9-position variants in this suffix range.
