Shrouding and keying protect the pins
A keying slot and mounting flange are built in — the slot ensures the cable plug can only be inserted one way, and the flange gives a mechanical anchor to the board through the through-hole solder joints.
Termination: press-fit or solder
The part is listed for both press-fit and solder termination — the press-fit option suits a solderless backplane assembly where rework matters; the solder tail works in a standard wave-solder process.
