    D38999/20WD04PN is a wall mount circular receptacle made to MIL-DTL-38999 specs. Many design engineers and procurement buyers pick this model for rugged field hardware that needs stable power and signal connections under continuous shock and vibration.
    It adopts high-strength alloy housing with the widely used scoop-proof shell. This simple design guards contact pins against bending when technicians mate connectors at an angle, a common issue during on-site assembly. Built-in silicone sealing blocks dust and moisture from entering the contact zone, keeping electrical performance steady over wide temperature shifts. Its shell plating delivers reliable anti-corrosion properties for long service cycles.
    This receptacle supports mixed power and signal contact layouts. Matching M39029 contacts can be supplied separately, along with pin extraction hand tools to simplify wiring and contact replacement onsite. It fits standard panel wall mounting directly; no extra machining is required.
    We handle the whole production workflow inside our factory. We build moulds for insulators and sealing bodies, while our CNC workshop turns socket shells and plug shells with tight dimensional control. Once all individual components pass pre-checks, experienced workers assemble each connector step by step.
    Every finished D38999/20WD04PN goes through separate QA inspection. Our QA team checks surface appearance, plating integrity, dimensions and electrical performance thoroughly. Only qualified products move into packaging.
    We stock core spare parts so sample shipments can be arranged quickly. Bulk production can be scheduled according to your project timeline. Global delivery options include DHL, UPS, FedEx and EMS. Tracking numbers will be shared right after goods leave our warehouse. Our engineering team can also prepare custom drawings if your project has special technical requirements.

    We run a full‑chain manufacturing plant dedicated to all kinds of industrial connector goods. Every single component you see on our finished items gets crafted right on‑site by our own workshop crews. Our in‑house workshops handle CNC turning for metal connector shells. We’ve got a small, skilled mould‑making team that works on custom tooling design. A big collection of finished mould templates is stored onsite, which helps us churn out insulating parts and silicone rubber accessories. All the core mechanical pieces‑‑contact springs, mating ports and anti‑interference shield springs‑‑are produced locally within our factory space. We built dedicated working stations to stamp and shape our metal contact terminals. Every terminal piece is made to satisfy the requirements laid down in the international M39029 industry standard. When our factory first got off the ground, most of our manufactured parts went to supply the AVIC Group. Our long‑time assembly workers carry out careful inspections during every production stage. They make certain every finished‑off connector meets the strict criteria of the MIL‑DTL‑38999 military‑grade specification.
