High-Speed Connector & Cabling Products
This week’s product roundup highlights some of the smallest, most reliable, most versatile, and highest performance high-speed connector and cabling products currently available on the market.
Samtec’s PCIE-LP Series low-profile PCI Express® Gen 4 edge card connectors feature Edge Rate® contacts on a 1mm pitch for optimized signal integrity performance; support one, four, eight, and 16 links for different bandwidth requirements; and meet industry demands for greater density and higher performance in compact electronics. The series’ ultralow 8mm profile saves 3mm of vertical space in standard size chassis compared to standard 11mm profile connectors with an identical 3.5mm contact wipe, providing both improved air flow and additional space to route other components over the connector, and its support of the PCI Express (PCIe) protocol ensures low latency, power savings, and guaranteed transmission. The series also achieves a 16GT/s bit rate and mates to standard PCIe expansion cards, 1.6mm-thick cards, and Samtec’s PCIEC Series PCIe jumpers. Polarization to ensure proper mating and surface-mount tails are standard options, and press fit tails are in development.
