Function & Usage: The Amphenol SAS/PCIe 4.0 (U.2&U.3) connectors are designed for next-generation servers, offering high-speed data transfer capabilities. They support both Serial Attached SCSI (SAS) at 24Gb/s and Peripheral Component Express (PCIe) at 16GT/s. The 68-position receptacle and header enable the implementation of high-speed SAS hard disk drives (HDDs) and PCIe-based devices. A molded guide post facilitates self-alignment during the mating process.
Advantages: These connectors are compatible with SFF8639 specifications and backward compatible with older SAS connectors (12G, 6G, 3G). They offer flexibility by allowing the same interface to be used for cost-effective HDDs and high-performance SSDs, supporting both SAS and SATA drives. Features like staggered contact lengths enable hot-plugging, and stamped clips provide robust PCB attachment and additional mechanical strength. Molded guideposts compensate for connector misalignment.
Application Scenarios: Ideal for processor and storage blade mezzanine cards, HDD carriers, external storage systems, interposer cards, and server storage solutions.
