Leveraging over fifty years of 3M's leadership in Insulation Displacement Contact (IDC) technology, the 3M Ribbon Cable Wiremount Socket Assembly, 451 Series, and the 3M Shrouded Boardmount Header, 452 Series, offer advanced connectivity solutions. The 451 Series provides a robust, compact connector with high connection density, available in multiple plating options for varying mate/unmate cycle requirements and optional friction latches for enhanced security. The 452 Series maximizes design flexibility with a minimal PCB footprint, mating with the 451 Series. It features standard shrouded headers with or without ejector latches, various plating options, and multiple mounting and packaging configurations for automated assembly. Both series are designed for reliable performance in demanding applications.
