The Amphenol FCI 68004-229HLF is a 29-position BergStik II unshrouded header, single-row, on the standard 0.100" (2.54 mm) pitch. It's a board-to-board interconnect intended for through-hole soldering — no IDC, no press-fit, just a straight solder tail that drops into a plated through-hole.
No latch, no polarization key, so the board layout must provide mechanical alignment if vibration is present. Through-hole solder termination with a 0.107" (2.71 mm) post length; the overall contact length of 0.525" (13.34 mm) gives enough tail protrusion for wave or hand soldering on a standard 0.062" board.
