3M cable socket 451 and 3M header 452 series
3M has been among the world’s leaders in connectors utilizing Insulation Displacement Contacts (IDCs).
The 3M cable socket 451 and 3M header 452 series are used together as a high density wire-to-board solution with a 1.27mm (0.050") pitch and a 0.635mm (0.025") pitch ribbon cable. This system uses insulation displacement contact (IDC) technology and cantilever U-contacts, proven reliable termination and space saving without sacrificing connection density.
