Custom D38999 Circular Connector Cable Assemblies – Wiring Solutions for Harsh Aerospace Operating Conditions

Our company specializes in the R&D and customized manufacturing of MIL-DTL-38999 military-grade circular connector cable assemblies and aerospace special wiring harnesses. These finished harnesses are widely applied in aerospace equipment, industrial installations, measurement & control systems and other severe working environments. Featuring excellent anti-interference capability, wide temperature resistance and vibration resistance, they are designed for signal transmission and power connection inside high-end equipment. We can supply braided shielded harnesses, special jacket cables, integrated coaxial wiring and other configurations.

We deliver one-stop customized wiring harness services based on customer drawings. Our professional engineering team handles the full workflow including solution evaluation and connector selection. We support low-volume prototype development as well as mass serial production. All cable assemblies are manufactured in strict accordance with military specification standards. Every product undergoes comprehensive electrical and mechanical reliability testing before delivery to guarantee consistent quality and on-time shipment.

The whole production process follows strict specifications. Raw wires are selected and cut according to wiring diagrams, followed by precision crimping and termination of connectors. Subsequent procedures include shielding treatment, insulation protection, braiding wrapping and labelling. After harness forming, each unit will pass continuity, insulation and withstand voltage tests. Products can only be packed and shipped once all inspection items are qualified.

If you have demands for aerospace connector harnesses or custom D38999 cable assemblies, please feel free to send us your wiring schedules and installation drawings. We will evaluate your project promptly and provide an accurate quotation.
