2.54mm Pitch Bottom Entry Female Header Connector Pass Through Socket Dual Row PCB Mount

A conventional female header mates from above, which forces the mating board to sit on top of the host PCB. This bottom entry version reverses the geometry: the contact cage opens downward through a window in the insulator, so a male header can enter from underneath the board. That single change lets a daughter card sit flush against the back of the main board, reducing total assembly thickness by the full body height of the connector. The pass through design also simplifies
