D38999/20WC04SB is a wall mount circular receptacle built according to MIL-DTL-38999 specs. Many system engineers and procurement buyers select this connector for field equipment that works under constant shock and vibration.

It adopts scoop-proof design to shield contact pins from bending damage. This solves a common problem when technicians mate connectors at an angle during on-site wiring. The high-strength alloy housing wraps all internal contact parts. Built-in silicone seal keeps dust and moisture out, maintaining stable electrical connections over long service time.

This receptacle supports mixed power and signal transmission. Matching M39029 contacts are packed separately, along with pin extraction tools. These simple tools make pin installation and removal much easier for field assembly. The plated shell provides good corrosion resistance in harsh operating environments.

After assembly, every D38999/20WC04SB goes through separate quality inspection. Our QA team checks appearance, dimensional tolerance, sealing performance and electrical continuity. Any defective items will be filtered out before packing. Popular models are kept in stock for fast delivery, and we accept minor custom adjustments to meet your project requirements.

If you need full technical information before final selection, send us your inquiry. We can provide datasheets, pin layout drawings and physical samples. Your engineering team can run lab testing and verify performance before bulk order placement.

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.
