Product Description
This multi-drop SATA wire harness connector assembly combines power and high-speed signal transmission in one compact cable set. A standard 4-pin power connector on the host side fans out to several SATA 7+15-pin cable connectors, allowing you to power and connect multiple 2.5"/3.5" HDDs or SSDs from a single power source.
The assembly uses oxygen-free copper electrical wire and shielded flat SATA cable to provide stable 5V/12V power and reliable 6Gb/s SATA data transmission. Gold-plated terminals reduce contact resistance and improve long-term corrosion resistance, while the molded housings enhance strain relief and mechanical strength. The harness is ideal for applications requiring neat wiring and quick installation in limited space.

Precautions
Confirm that the total current of all connected drives does not exceed the power rating of the 4-pin input and system power supply.
Avoid excessive bending or twisting of the flat SATA cables and bundled harness to maintain signal integrity and mechanical life.
Ensure connectors are fully inserted and latched before powering on to prevent intermittent contact or data errors.
Do not route the cable near sharp edges, high-temperature components or strong electromagnetic sources; use proper cable management clips or ties.
For special environments (high temperature, vibration, automotive or industrial use), consult for customized wire gauge, jacket material and additional shielding.
