D38999/26WC04PA belongs to the widely‑used D38999 circular connector family. This is a plug‑style unit built to hold up against tough working conditions.
This model comes with 4 contact positions, designed for stable power and signal transmission for field‑mounted equipment. Its WC‑series shell structure delivers reliable coupling performance, keeping connections tight even under vibration and mechanical shock.
Good sealing and corrosion‑resistant shell finish are its key advantages. It can block dust and moisture, so the connector stays stable when deployed outdoors or inside demanding industrial systems.
Customers often select D38999/26WC04PA for ground test devices, industrial control hardware and heavy‑duty machinery assemblies. It maintains good interchangeability with mainstream equivalent parts available on the market.
We produce this connector with full in‑house workflow, covering mould making, CNC shell machining, assembly and finished‑item inspection. Custom contact layout, surface plating options are acceptable per project request. Reach our sales team if you need datasheet, sample evaluation or technical support for your project.
Mass production
Every D38999/26WC04PA circular plug goes through our complete in‑house manufacturing steps before delivery.
We start with custom mould development for insulators and sealing bodies matching this model’s drawing requirements. Metal plug shell parts are processed on our CNC machines. Once insulators, sealing bodies and metal shells are finished, our technicians assemble these parts into complete D38999/26WC04PA connector units.
Assembly finished products will go through strict inspection work. We run dimension check, appearance screening and performance testing with professional inspection equipment. Any non‑conforming items get filtered out at this phase.
Qualified D38999/26WC04PA units move on to packing. Parts are sealed into separate plastic bags, small contact components are stored in marked bottles, and shock‑absorbing foam is used inside cartons to avoid damage in transit.
After packing work is done, goods can be shipped globally. We cooperate with DHL, FedEx, UPS and other mainstream carriers for air or sea transport. Tracking information will be provided once the order leaves our warehouse.
With 13‑years of hands‑on experience making D38999‑series connectors, we keep core production steps inside our own factory. This gives us better control over product quality and order lead‑time for D38999/26WC04PA. You can reach our sales team if you need samples or project‑related technical data.
