SATACables ECX-12 eSATA cable 12 inch Male to Female
A 12 inch Male to Female eSATA cable extending SATA I or SATA II data connections with 26 AWG solid copper conductors and 15 microinch gold-plated contacts
- Cable Length1 ft.
- Extends SATA I or SATA II cables with a 12 inch male-to-female link
- 15 micro-inch gold-plated contacts resist corrosion for reliable signal transfer
- 26 AWG solid tinned copper conductors with foil shielding reduce crosstalk to -26 dB max

- UL 94V-0 rated connectors and 80 °C PVC jacket meet safety and temperature requirements
What this cable does
The SATACables ECX-12 is a twelve‑inch internal SATA extension with a male SATA plug on one end and a female eSATA port on the other. It lets you lengthen an existing SATA I or SATA II data connection by one foot. The cable uses 26 AWG solid tinned‑copper signal pairs wrapped in aluminum‑mylar shielding and a 2.2 mm × 7.80 mm PVC jacket rated for 80 °C.
How the connectors change the link
The male‑to‑female layout turns a fixed‑length SATA lead into a removable extension, so a drive or dock can sit further from the motherboard without replacing the original cable. Gold‑plated contacts (15 µ over 50 µ nickel) and a UL 94V‑0 rated housing keep the 100 Ω impedance stable up to 4 500 MHz with crosstalk below ‑26 dB.
What to verify before ordering
Check that your host port is a standard internal SATA header and that the device you are attaching presents a male eSATA plug. The extension only carries data; power must come from a separate SATA power cable. Confirm the one‑foot reach suits your chassis layout, as longer 20‑inch versions exist if more slack is needed.

Questions about this item
Will the 15u gold-plated contacts on the ECX-12 need re-plating or replacement after repeated mating cycles?
The contacts use 15u gold over 50u nickel; gold resists oxidation so re-plating is not expected under normal bench use.
At what point does the 6 dB attenuation limit from 10 MHz to 4500 MHz become the bottleneck for SATA II 300 speeds?
The cable meets the 6 dB max attenuation spec across the full SATA II bandwidth, so the limit does not appear before the interface ceiling.
How warm does the 80 °C PVC jacket get when the cable runs at 30 V continuously all day?
The jacket is rated for 80 °C ambient; at 30 V the conductor current is minimal, so the cable stays near room temperature.
