451 Series Sockets and 452 Series Board-Mount Headers from 3M PIO | DigiKey

M's 451 series sockets and 452 series board-mount headers deliver a compact, fine-pitch connector system for reliable wire-to-board connections. The 3M 451 series socket assemblies and 452 series board-mount headers combine a 1.27 mm (0.05 in) pitch with small packages to minimize PCB space. The 451 series ribbon cable socket offers a robust, high-density connection with friction latch options for protection against accidental disconnect. The 452 series shrouded header mates with the 451 series and is available in straight or right-angle mount, through-hole or SMT termination. Both series offer 30 uin gold or gold flash plating for different mate and unmate cycle needs, and the 452 series supports tape-and-reel packaging for automated assembly. These connectors are well suited for wearables, medical devices, IoT, and industrial PCB applications requiring durable, space-saving interconnects.
