The 20 positions in two rows give a 10-per-row layout. The mated stacking height is 4mm, which sets the z-height between the two parallel boards; confirm that your enclosure or mezzanine standoffs match that dimension. ## What it mates with The outer shroud contacts on this header align with the receptacle's inner contacts. If you are stocking spares, stock both halves or neither — an orphan header without its socket is dead stock on the shelf.","metaTitle":"Hirose DF12(4.0)-20DP-0.5V(86) Header, 20 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12 series 20-position header, 0.50mm pitch, 4mm stacking height, gold contacts.
