Micro SATA Connectors


Molex introduces the Micro Serial ATA ( SATA ) interconnect solution for 1.8" form factor drives and backplane applications.

In April 2007, the Serial ATA International Organization ( SATA-IO ) announced the release of new specs for the SATA interconnect solutions. The new 2.6 revision covers the addition of new features to the specs making SATA available for new applications. One of the new features is the provision for the application of 1.8" SATA form factor drives in laptop computers, set top box and game console.

Molex Micro SATA connectors are compliant to SATA-IO standards with respect to the mating interface. These standards define features such as 7 signal pins, 9 power pins with power segment key, staggered contact lengths for hot plugging, guide posts and pockets for blind-mating, friction locking for cabling and high data-transfer rate of 3.0Gbps . The combo device plug supports internal 5.00mm and 8.00mm slim 1.8" form factor drives while the right angle Micro SATA combo receptacle supports backplane applications.

The connectors contained in this release are ELV and RoHS compliant. They are also lead free process compatible.

Molex is an active member of the SATA-IO . The working group is responsible for developing and specifying Serial ATA interconnect standards.
