Product Description
This external SATA data cable connector links two eSATA 7-pin
ports, providing a stable, high-speed serial transmission path for
hard-disk drives, SSDs, RAID arrays, DVR recorders, and industrial
PCs. The cable adopts shielded copper conductors and a robust round
PVC jacket to reduce signal crosstalk and EMI, ensuring reliable
performance for continuous data transmission.
Gold-plated contacts and high-temperature connector housings help
maintain low contact resistance and secure mating, even under
frequent plug-and-unplug operation. The male-to-male connector
design is suitable for direct connection between external HDD
enclosures, docking stations, and host eSATA ports. OEM/ODM options
are available, including cable length, jacket color, labeling, and
custom wiring requirements to match different PCB and system
layouts.

Applications
External 2.5"/3.5" HDD and SSD enclosures connected to desktops,
workstations, or servers
Industrial computers, data loggers, and automation control systems
requiring reliable external storage links
RAID arrays and storage expansion units in data centers and small
server rooms
DVR, NVR, and video surveillance systems that need stable
high-speed storage transmission
Precautions
Confirm that both devices support the eSATA 7-pin interface before
installation.
Avoid excessive bending, pulling, or twisting of the cable;
recommended minimum bending radius is at least 8–10 times the cable
diameter.
Ensure connectors are fully inserted and latched to prevent
intermittent contact or data loss during vibration.
Keep the cable away from strong power lines or high-interference
equipment to maintain signal integrity.
Do not use the product in environments that exceed the rated
temperature or voltage, and replace any cable with damaged jacket
or deformed contacts.
