Product Description
This custom power wire harness connector is designed for reliable power and signal transmission between a power supply unit and downstream electronic loads. A 12-pin male connector mates with a matching female connector, using copper alloy terminals to ensure low contact resistance and stable current delivery.
Multiple insulated electrical wires are bundled in a neat harness and protected by a black braided sleeve, improving wear resistance and heat dissipation while keeping cable routing clean in dense server or automotive compartments. The connector and terminal system is suitable for both PCB-mounted headers and panel-mount sockets, supporting high-current power lines as well as low-level control or sense signals in one assembly.
Pin count, wire gauge, and harness length can be customized to match specific PSU, inverter, battery pack, or control module interfaces, making it an ideal solution for OEM and ODM projects that require tailored cable connector assemblies.
| Connector Type | 12-pin power connector assembly, male–to–female |
| Connector Style | Rectangular plastic housing, locking latch |
| Contact Type | Tin or gold-plated copper alloy terminals |
| Number of Pins | 12 pins (pin count and layout customizable) |

| Flame Class | UL94 V-0 housing material (on request) |
| Application Field | Server power distribution, GPU/CPU power cable, industrial control, automotive electronics |
| Customization | Pin definition, wire color, label, over-molding, and packaging OEM/ODM |
| Compliance | RoHS-compliant, halogen-free options available |
Applications
Power harness between a server PSU and backplane, GPU board, or storage module in data-center and edge-server equipment
Power and signal connector cable for automotive electronic control units, battery management systems, or DC/DC converters
Industrial equipment wiring inside inverters, motor drives, and smart power distribution boxes
Custom wire harness for robotics, telecom racks, and embedded systems where compact, high-current connectors are required
Confirm the connector pinout, male/female orientation, and pitch match the mating PCB or device before installation.
Do not exceed the rated current of each terminal; choose appropriate wire gauge when requesting customization.
Avoid tight bending near the connector housing or constant mechanical stress on the harness to prevent conductor fatigue.
Route the cable away from sharp edges, hot surfaces, and strong electromagnetic interference sources where possible.
Ensure all terminals are fully inserted and locked in the housing; incomplete insertion may cause overheating or intermittent contact.
