HSEC8 High-Speed Edge Card Connectors

Samtec’s Edge Rate® sockets are available in vertical, pass-through, right-angle, or edge mount orientations

Samtec’s full line of high-speed edge card connectors are available in a variety of pitches and orientations. The popular 0.80 mm pitch Edge Rate sockets (HSEC8 series) are available in vertical, pass-through, right-angle, or edge mount orientations, and with elevated stack heights to 30 mm. The HSEC8-DP series is a differential pair version, rated for speeds of 28 Gbps NRZ/56 Gbps PAM4, with 8 to 56 total pairs and optional rugged weld tabs. This double row socket mates with standard 1.60 mm (0.062″) thick cards and features Edge Rate contacts for increased cycle life. The smooth, broad, milled mating surface of the Edge Rate contacts minimizes the effects of broadside coupling, which decreases crosstalk for superior signal integrity performance. Increased impedance control is achieved by a straight, more consistent material cross-section. Robust when mating and unmating, this contact system also features a long contact wipe up to 1.5 mm, which improves the mating angle tolerance. In addition, Edge Rate contacts are suitable for a variety of high-speed protocols and standards.
