Application Note
Note: Additional key combinations and locations are available, please contact Molex
Note: Tin/Lead press-fit zones are used for bare Copper or Gold plated PCBs
The backplane headers are delivered as modules and are press-fitted into the backplane1 This
allows maximum flexibility with minimum inventory1 Note that the guidepins are an integral
part of the headers1 This also means that you may have different part numbers for left-
handed and right-handed headers1 You must consult the customer print to determine the
appropriate part number for various combinations of guide pin locations (2) and coding pin
orientations (8)1
Note: The guide pin must mate with the top position on the mating receptacle to clear the board edge1 Therefore, if
guidepin headers are used on each end of a header array, you should select one with the pin in location B and the
second with the guidepin in location A1
