Micro SATA
FEATURES AND SPECIFICATIONS
Molex introduces the micro Serial ATA (SATA) interconnect solution for 1.8” form factor
drives and backplane applications.
78285 / 78103
Combo Plug
In April 2007, the Serial ATA International Organization (SATA-IO) annnounced 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 both HDD
(hard disk drive) and SSD (solid state drive) types. Applications include laptop computers, set
top boxes and game consoles.
78320 / 78109
Combo Receptacle
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.
