Product Description
This braided backplane power and data connector cable harness is designed for compact server and industrial computer platforms where a proprietary board connector must be adapted to standard Slimline SATA and 15-pin SATA power interfaces. High-quality copper wire, precision-crimped terminals and robust over-molding deliver stable electrical performance and low insertion loss for both power and high-speed signal transmission.
The round cable construction with PET braided sleeving resists abrasion and bending fatigue, while helping organize wiring inside dense 1U/2U chassis. Color-coded power lines and clearly keyed connectors reduce installation errors and make field maintenance easier. With full OEM/ODM customization capability, this harness can be tuned for different PCB pitch, connector types and cable lengths used in automotive data recorders, embedded computers and storage expansion modules.

Applications
Connecting external eSATA ports to internal SATA hard disk drives or solid-state drives
Expansion of storage capacity for DVR/NVR systems, industrial control computers and embedded systems
Data transmission between host controllers and 2.5"/3.5" SATA drives in servers and workstations
Test fixtures, evaluation boards and custom PCB assemblies requiring SATA signal routing
Precautions
Confirm the interface type and pin definition of both host and device before installation to avoid mismatched connectors.
Do not exceed the recommended cable length for 6 Gbps operation; for long-distance routing, select a lower-speed setting or consult for a customized high-performance cable.
Avoid excessive bending, twisting or pulling near the connector ends; maintain a bend radius larger than 10× the cable diameter for reliable transmission.
Keep the connector terminals clean and free of dust or oxidation; insert and remove the cable vertically to prevent damage to the mating connector on the PCB or device.
When used in high-temperature or high-vibration environments, choose reinforced and fully shielded customized versions to ensure long-term stability of power and signal transmission.
