Fully shrouded, three wall and low profile box header connectors are available to provide a reliable mating surface for sockets having a 0.100 in. (2.54 mm) x 0.100 in. (2.54 mm) contact spacing. The headers have male pins on their mating side and offer the designer a choice of either wire-wrap or solder posts in various lengths on the opposing end. The customer can specify either straight or right-angle contacts that allow sockets to mate with headers at right angles or parallel to the mating PC board or wire-wrap plane. Optional ejection latches in various sizes are available to mate with strain relief or non-strain relief sockets. Polarization ribs are securely molded into place, eliminating the need for gluing polarizing keys to the header base. These ribs are easily removed for applications requiring a non-polarized interconnection.
