Design-enhanced Micro SAS connectors now include dual-drive stacked
receptacles with an integrated ground plane and a protective pin cover
for greater reliability in compact storage applications
Molex’s Micro Serial Attached SCSI (Micro SAS) connectors are the
next-generation of 1.8" storage serial I/O solutions designed for compact,
high-speed, high-bandwidth SAS applications including Host Bus Adapters
and Storage Servers.
Leading Molex’s family of Micro SAS plug and receptacle products is the
78495-0001 dual-stack right angle receptacle. This halogen-free, through-hole
interconnect stacks two high-speed 1.8" Solid State Drives (SSDs) instead of
one, giving storage users twice the drive density of a single right angle equivalent
(series 78395). The connector is now shipped with a pin cover that protects all
rear terminals from any damage caused by handling or shipment.
A key highlight of this dual-stack connector is the patented Integrated Ground
Plane feature. This feature consists of a specially stamped terminal that shields
any cross talk between the two adjacent high-speed differential pairs on each
side of the plane, improving the connector’s signal integrity and electrical speed.
Because the Integrated Ground Plane replaces any need for separate grounding
pins to be used for the differential high-speed contact pairs, it gives the
connector more PCB space-savings, since it terminates beneath the connector
only as a single, throughhole soldertail.
One other key feature of the dual-stack connector is its unique overlapping,
staggered terminal design within the differential signal pair located on each
side of the Integrated Ground Plane in the upper region. This overlapping
configuration facilitates stronger coupling within the differential signal pair and
induces a higher signal integrity for the connector.
The unique 45-degree terminal bend design of the dual-stack receptacle allows a
shorter electrical path between the mating contacts and the PCB, and enables a
smoother signal transmission and therefore, higher electrical performance of the
connector. Fully compatible with Molex Micro SATA drives and enabling fast
data transfer rates of up to 3Gbps, this connector satisfies the SAS 2.0 and the
SFF-8486 Specifications*.
Molex right angle straddle-mount plugs are available with (series 78528) and
without (series 78394) drive-holder features to meet low-profile height
requirements. Together with the single right angle receptacle (series 78395),
these plugs feature a high data transfer speed of 6Gbps and satisfy the SAS 2.0
and SFF-8486 Specifications.
