Edge card sockets suit AI hardware designs

HSEC6-DV is used in prototypical PCIe 6.0 AI hardware designs serving as the interconnect between the motherboard and add-in cards.

The edge card socket’s rugged Edge Rate contacts, in a differential pair configuration on 0.60 mm pitch, are optimised for signal integrity performance and high cycle life.

HSEC6-DV is compliant to SFF-TA-1002 x4 (1C), x8 (2C), x16 (4C and 4C+). The edge card socket strip is available with 28, 42, 70, and 84 positions per row, and mates with 1.60 mm (.062”) thick cards. Optional weld tabs provide extra mechanical strength of the connector to the PCB.

RoHS compliant and lead-free solderable, the HSEC6-DV is rated at 240 VAC, and the current rating is 1.92 A with 2 pins energised. 

Mating cable assemblies (GC6 Series) are also PCIe 6.0 compatible, supporting 64 Gbps PAM4 (32 Gbps NRZ) applications. The cable is 34 AWG Samtec Eye Speed ultra-low skew twinax. GC6 cable assemblies are available in 28, 42, and 70 positions, and are standard with 100-ohm differential pair signal routing.

HSEC6-DV is the latest in a full-line of Generate high-speed edge card connectors, rated up to 56 Gbps PAM4, on 0.80, and 1.00 mm centerline.

These products are available in vertical, right-angle, edge mount, and pass-through orientations. They are also available in power/signal combos, with press-fit tails, locks and latches.
