Product Description
This SATA power to 4-pin PCB connector cable provides a compact way
to route power and low-current signals from a standard SATA power
interface to a small board-mounted connector. The harness uses
high-quality stranded copper wire and reliable crimped terminals to
maintain stable power transmission and consistent signal integrity.
The SATA side mates with common power outputs found on PC and
server power supplies, while the 4-pin micro connector side plugs
directly into control boards, fans, indicator modules, or sensor
PCBs. Color-coded wires help identify circuits quickly during
installation and maintenance. Custom options are available to match
specific PCB footprints, voltage rails, and current requirements.

Applications
Power and control connection between PC/server SATA power outputs
and small control boards or sensor modules.
Internal wiring for industrial control cabinets, embedded systems,
and IoT gateways using SATA-based power rails.
Customized harnesses for LED indicator boards, low-power pumps,
fans, or relay boards in automation equipment.
Prototype and OEM cable assemblies where a compact PCB connector is
needed on one side and standard SATA power on the other.
Precautions
Confirm the pin assignment and voltage levels at both connectors
before use; incorrect wiring can damage the PCB or power supply.
Use within the specified current and temperature ratings; avoid
powering high-current loads through circuits intended only for
control signals.
Do not plug the SATA connector into a data-only SATA receptacle; it
is designed for power interfaces.
Avoid excessive bending, pulling, or twisting of the cable,
especially near the connector terminations.
Ensure all connectors are fully seated and latched before powering
on the system, and periodically inspect for wear, discoloration, or
loose terminals during service.
