In summary, 3M’s new 450 Series is a complete end-to-end interconnect system intended for wire-to-board applications using .025” flat ribbon cable. It is a two part system consisting of a boardmount header and a wire-mount socket. The mating components are designed on a 1.27 mm or .050” grid. When compared to systems based on the 2.54 mm or 2.00 mm grids, the finer pitch saves valuable space on the printed circuit board, yet still delivers on performance, reliability, and cost savings.
