52-position breakaway header, 2.54 mm pitch
The 4-103326-0-26: Gold-plated mating contacts rated 3 A per position, through-hole right-angle mounting with solder termination. The unshrouded push-pull design suits board-to-board or cable connections where the mating half provides the retention.
The pitch and footprint are standard across the Mod II series — match the position count to the circuit count required; the board layout for a 52-position header is the same as for any 52-position Mod II part at this pitch.
