22-Pin Breakaway on a 0.100-Inch Grid
The 6-146252-1: This is a 22-position, dual-row unshrouded header from TE's AMPMODU Mod II series. The breakaway design means the 22-position strip can be snapped to shorter lengths if the BOM calls for fewer circuits, though this part ships with all positions loaded.
As an unshrouded header, it mates with standard AMPMODU Mod II receptacles or any 0.100-inch pitch IDC socket that accepts 0.025-inch square pins. Termination is through-hole solder; the square pins (0.025-inch square typical for the series) insert into plated through-holes and are wave-soldered or hand-soldered.
