This type of header (receptacle) contains female sockets within a plastic housing and is meant to be mated with a rectangular cable connector or a male pin header for board-to-board connection. These come in a variety of position and pitch options, with some having a breakaway option to manually change position count with ease. Mounting types include panel mount, board edge, stacking, surface mount, and through-hole.
