Product Description
This assembly is a multi-drop SATA connector harness that combines
both data and power lines in a single, organized cable set. A
single host interface on the PSU or controller side is fanned out
to several SATA 7+15-pin connectors, allowing multiple HDDs or SSDs
to be powered and linked using one consolidated harness.
Shielded SATA data cables maintain low crosstalk and stable signal
integrity at up to 6 Gb/s, while the thicker power wires guarantee
reliable 5 V and 12 V delivery to each drive. The compact
connectors, pre-crimped terminals, and bundled routing make
installation fast and tidy in dense storage bays and narrow server
chassis. Custom harness designs are available to match the layout
of storage trays, backplanes, and proprietary PCBs.

Applications
Mass-storage servers, NAS enclosures, and JBOD chassis requiring
multiple SATA drives on one harness.
Industrial PCs and DVR/NVR systems where several HDDs or SSDs share
a common controller or backplane.
OEM storage modules and RAID systems that need pre-terminated data
and power cabling for quick assembly.
Upgrade kits for tower or rack systems, helping organize wiring and
reduce clutter in the drive area.
Precautions
Confirm that the total current of all attached drives is within the
PSU rail and harness rating.
Check SATA connector orientation and keying to avoid damage to
drive or host ports during insertion.
Do not sharply bend or pinch the red SATA ribbon cables; excessive
stress may degrade signal performance.
Keep data cables separated from high-noise power lines or fans
whenever possible to minimize interference.
Periodically inspect connectors and wires in high-vibration or
high-temperature environments, and replace any harness showing
insulation cracks or discolored terminals.
