Developed by the 3M Electronics Solutions Division, the Ribbon Cable Wiremount Socket Assembly 451 series and Shrouded Boardmount Header 452 series are touted for military, aerospace, communications and high-performance computing applications. The header and socket interconnect solutions measure .050" x .050" small for space-saving purposes and high connection density.

The Ribbon Cable Wiremount Socket Assembly and Shrouded Boardmount Header connect .025" pitch ribbon cables to printed circuit boards (PCBs). A variety of .025" pitch ribbon cables are also available from 3M, forming a complete, end-to-end system of header, socket and cable.

The 451 Series incorporates 3M insulation displacement contact (IDC) technology in the connector, helping maintain secure connections and high signal integrity. The IDC connector's mass termination capability allows the termination of 30 lines in a single cycle, reducing the need for expensive automated termination equipment and allowing manual cable assembly operations. Available friction-latch configurations and an optional strain-relief accessory can further increase connection reliability. An optional, unique header ejector latch mechanism provides positive latch and ejection capability with minimal size addition.

The 452 Series is available in a variety of configurations in order to maximise design flexibility while minimising PCB footprint. Tape-and-reel packaging for the SMT version of the header is available for automated placement applications, and PCB standoffs help enable pin-in-paste processing capability.
