Product description
Our D38999/20FD19PE belongs to MIL-DTL-38999 Series III circular connectors. It is a square flange panel mount receptacle with 19 contact positions, featuring threaded coupling, excellent EMI shielding, anti-vibration and high-temperature resistance.
Widely used in aerospace, avionics, defense equipment and harsh industrial environments. Compatible with standard M39029 crimp contacts. We support cross replacement, stable inventory and flexible MOQ.


Workshop
Our factory owns a standardized full‑process production workshop for circular connectors. Independent working zones cover CNC metal machining, die‑casting, surface anti‑corrosion treatment, insulator injection molding, dust‑free assembly and multi‑item performance inspection.
Precision numerical‑control lathes process metal housings with strict dimensional tolerance control. Automatic plating equipment treats contacts for stable gold‑plated surface. Insulating components are injection‑molded in dust‑free workshops. Workers assemble seals, bases and shells on dust‑free workstations.
Every batch of finished goods undergoes strict sampling inspections including water‑resistance, shock‑vibration, high‑low‑temperature and electrical‑conduction tests. We support mass standardized production and customized processing to satisfy diverse client demands.



Exhibition
We regularly attend global‑scale exhibitions for industrial spare parts, automated machinery and electronic components. Our professional team demonstrates connector installation steps, vibration‑resistant locking function and waterproof capability for overseas purchasers from new‑energy, engineering‑machinery and automation industries. We introduce technical parameters, OEM customization plans and bulk‑order delivery solutions. Reliable product quality and complete accessory systems help us build long‑term partnerships with worldwide buyers.


Package
Every connector set adopts professional cross‑border‑transport packaging.
The main connector body, spare contacts inside the marked plastic bottle and multi‑color extraction tools are separately stored. Anti‑static bags are used to shield precision metal terminals from static damage.
Shock‑proof pearl cotton fixes all parts inside thickened carton boxes to prevent scratch and collision damage in long‑distance sea or air shipping. Outer cartons are printed with model number, specification and moisture‑proof labels. A packing list is attached for buyers to check accessories quickly after receipt. Moisture‑proof, shock‑resistant and anti‑static packaging keeps goods intact during international logistics.
