D38999 Circular Connectors for Aerospace & Defense Applications

If you’ve worked in aerospace component procurement long enough, you know how tricky it can be to lock down reliable circular connectors for field deployments. Lots of our clients keep coming back to the D38999 range, and there is a good reason behind this.

 We stock Series I, Series II and Series III units to cover most airborne connection work. You get high‑density contacts, solid EMI/RFI shielding, plus bayonet quick‑lock mechanism. Do not mix these up with regular industrial connectors. These units must hold up against heavy vibration, salt fog, moisture and mold — conditions you simply cannot avoid in real‑world aerospace jobs.

 From past orders, wall‑mount, box‑style and nut‑lock receptacles are what people ask for most. Quite a few engineers reach for short‑shell Series‑III parts, simply because equipment cabins barely leave any spare space. Temperature operating window runs ‑65℃ to +200℃. Sealing covers plug face and cable rear end for IP‑grade protection.

 We do not only carry D38999 parts, by the way. Arinc600 avionics modules and Russian СНЦ‑23 type connectors are also on hand for those special retrofit projects.

 Hardly any customers buy raw connectors alone these days. Custom cable assemblies make up a big chunk of our monthly order volume. Buyers will send over pin‑out tables, desired cable lengths and their shielding requirements. Our technical staff go through every drawing prior to manufacturing. Trust me, this small step saves so many headaches when hardware gets installed at their site.

 These parts fit avionics, ground vehicles as well as naval hardware. They handle complex signal transmission and limited power feed‑through. When it comes to defense‑related purchasing, mechanical robustness often weighs equally important as electrical parameters.

At Luoyang Kewei RF Technology, we supply ready‑to‑ship standard stock items. We also accept alterations when projects call for non‑standard specs.
