  • Features and benefits of 3M™ Molded Assembly 2M Series

    Molded cable/connector assemblies feature durable flat cables for long-term performance in some of the toughest environments. Cable is concealed inside the connector body, greatly reducing the possibility of dirt and moisture entering through the connector while virtually eliminating the need for cable house assembly and parts management. The insulation material on the 3M assembly 2M series completely encases the gas-tight insulation displacement area and is thermally fused to the connector body, providing exceptional strain relief against pulls and other exterior forces. Cables can be specified with molded-in strain relief at points along the cable as well.

    B. Cable and connector are thermally fused for exceptional strain relief

    C. Individual contacts are isolated with thermoplastic cell walls

    D. Recesses accommodate adjacent posts in continuous rows

    The right cable/connector assembly for your application

    3M Molded Assembly 2M Series connectors can be fully customized to meet exact specifications. One-piece molded assemblies can be specified with a range of 3M cables as well as DIP and PCB connectors. Sockets mate with industry standard 2 mm x 2 mm headers and plugs, with an optional ear latching mechanism for mating to latch/eject headers. A center bump is available on sockets for polarized connections.  Cable assemblies use round conductor flat ribbon cable on industry standard .050” (1.27 mm) or 1 mm pitch.
