Product details

56-Pin Breakaway Header for Board-to-Board and Cable Interconnects

Board Layout and Routing Considerations

The 0.230" (5.84mm) mating pin length and 0.095" (2.41mm) post length give a total contact length of 0.425" (10.80mm), which sets the board-to-board stack height when mated with a receptacle. This is common for BergStik headers used with IDC sockets or crimp housings that have their own polarization features.
