U.2 連接器

U.2 (SFF-8639) SAS/PCIe 3.0 connectors are designed for next generation storage application with SAS 12Gb/s and PCIe 8Gb/s per lane. The molded guide posts allow device plug and receptacle to self-align during mating process.

Features

- Capable of meeting 12Gb/s SSDs and HDDs or PCle
based devices at 8Gb/s
- Footprint backward compatible with 6G and 3G SAS connectors
- Durability 500 mating cycles
- SAS/PCIe connectors enable SFF8630, SFF 8680 and SFF8432 interfaces
- Backward compatible with 6Gbps SAS, SATA and
3Gbps SFF8482 connectors
- Supports both SAS and SATA drives
- Supports up to 4 ports PCIe based devices
- Staggered contact lengths
- Stamped clips act as connector retainers for robust
PCB attachment
- Molded guide posts help mating halves to self-align by providing angled lead-in

Benefits

- Implementation of high speed SSDs (Solid State Drives) and HDDs (Hard Disk Drives) allows compatibility between unshielded dual and multiport interfaces
- Same interface can be used for cost-effective storage HDD as well as higher performance server
- Address the needs of both mission critical and bulk storage applications
- Provide sequential contact mating for hot plugging
- Provide additional mechanical strength after soldering
- Compensates for connector misalignment
