Product pictures

The D38999/26WJ20PN heavy‑duty circular male plug belongs to the widely‑used industrial‑grade round interconnect series.

It comes with 20 detachable crimp‑style gold‑plated male pins, fast‑twist bayonet locking housing and built‑in waterproof sealing gasket. The full set supplies assorted plastic extraction tools for convenient terminal replacement, inspection and maintenance.

This sturdy wiring connector delivers steady power and signal transmission under harsh working‑site conditions. It works well for civilian‑grade equipment, such as automated production machinery, transport‑on‑board electronic assemblies, renewable‑energy facilities, medical testing devices and marine control hardware.

Product descripton

Our D38999/26WJ20PN bayonet‑type male circular connector is engineered for long‑time reliable cable connection within demanding industrial operating surroundings.

This 20‑position male‑pin plug adopts independent removable crimp‑on gold‑plated contact pins. Premium gold‑plated surface effectively lowers contact resistance, prevents metal oxidation and cuts wear‑and‑tear from repeated plug‑in cycles, maintaining outstanding electrical conductivity.

The high‑strength anti‑corrosion alloy‑made connector shell installs a blue silicone sealing ring on the joint. The sealing component stops moisture, fine dust and industrial pollutants from entering the inner cavity. The classic bayonet twist‑lock mechanism enables quick locking and separation without complicated screw‑fixing steps.

Every single male contact pin can be crimped firmly onto insulated wires. Multiple‑color plastic release tools are included to help operators take out, swap and examine terminals easily.

It can pair up with the matching female receptacle from the same connector series. This heavy‑duty interconnect fits signal‑transmission and low‑to‑medium‑current power‑connection jobs for all kinds of civilian industrial electronic devices.

Workshop

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.

Exhibition

Great client service is something our team always prioritizes. We aim to deliver a pleasant buying journey for every overseas partner. We make regular trips to major electronics trade fairs around the industry. These in‑person meet‑ups make it simple for us to chat with buyers, gather real‑world usage feedback and work out ways to refine our goods. Face‑to‑face conversations like these allow us to build dependable, long‑lasting business partnerships with clients all over the world.

Package

Wondering how we pack connectors before shipment? Let me walk you through our real packing routine step by step.

First off, every unit gets wrapped with soft tough anti-scratch foam right before leaving our workshop. Rough highway and sea shipping always bring bumps and friction, and this foam keeps metal shells free of ugly scratches that often come from poor packaging.

After foam wrapping, we place each connector into a separate ESD sealed box. These internal pins and inserts are extremely delicate; static electricity can burn out tiny parts without visible signs. This sealed box blocks static risk entirely, and it’s one of our most important protective steps.

Our packing team will double-check every finished package manually. Only confirmed good items go into reinforced dedicated cartons. We print part number, batch count and total quantity clearly on carton surfaces, so your warehouse team can sort and stock goods quickly once delivery arrives.

You can pick international express, air freight or sea shipping freely. Our logistics team adjusts arrangements fully to match your preferred delivery method.

All outer cartons go through extra reinforcement work. They resist compression and shock far better than ordinary generic cartons.

Long cross-border shipments always have shaking and squeezing on the way. Our layered packing design absorbs most impact, cuts transit damage greatly, and makes sure every single connector lands intact at your site.
