When a drawing, a legacy bill of materials or an incoming RFQ hands you a string such as D38999 26WG11SN, the real question is what each segment commits you to and what you should order next. This hub splits that string into readable segments, marks which details are already published for model D38999 26WG11SN, and routes you toward the right shell style, mounting choice and inquiry. Whether you are comparing a MIL-DTL-38999 Series III circular connector against another family member, or you simply need a MIL-DTL-38999 connector quoted for a defined environment, start here and leave knowing exactly what to ask for.
These are the details the product page states for this model. Nothing is added here that the page does not show, so this table is safe to copy into a requirements review.
| Field | Published detail | Status |
|---|---|---|
| Model / part number | D38999 26WG11SN, listed on the page as No.D38999 26WG11SN | Published |
| Series | MIL-DTL-38999 Series III | Published |
| Connector type | Circular connector, aerospace plug and socket configuration | Published |
| Environmental attributes | Vibration resistant, salt spray resistant, high temperature resistant, waterproof, shockproof | Published |
| Sealing and protection | Sealed construction stated to support waterproof use and to help protect the interface from corrosion and contamination | Published |
| Connection structure | Built for repeated mating cycles, vibration and shock | Published |
| Contact design | Controlled contact design stated to support stable signal and power transfer | Published |
| Form factor | Compact circular body, described as helping keep wiring organised in dense enclosures | Published |
| Numeric ratings | No numeric or tabular ratings are listed, so contact count, current and voltage rating, and a temperature range in degrees stay open items | Confirm with engineering |
| Ordering route | Quote and inquiry based. The page offers Get a Quote and Get The Latest Quote paths with no price or checkout shown | Published |
Buyer decision: treat every published row as a shortlisting fact and every confirm row as an open question. If your design depends on a numeric rating, put it in the inquiry before the layout is frozen.
A part string is a contract in shorthand. Below is the same string split into six positions, with an honest label on each one: what this page actually confirms, and what still needs a human answer.
This is general orientation rather than performance data for this model, and it exists for one reason: to tell you quickly whether you are reading the right page. Confirm the exact series requirement against your drawing before you commit.
| If your drawing reads | What that generally signals | Your next step |
|---|---|---|
| Series I | An earlier generation of the same family, typically associated with bayonet coupling conventions | Send the drawing so the shell style and contacts can be matched in the catalog |
| Series II | A different coupling and profile convention within the same family, often chosen where space is tight | Confirm whether a threaded coupling is acceptable in your harness before switching series |
| Series III | The family this page covers, generally associated with threaded coupling and a harsh-environment emphasis. D38999 26WG11SN belongs here | Stay on this page and work through the shell style and environment decisions below |
| Series IV | A low-profile threaded convention within the same family | Send the drawing and the panel envelope for a match |
Buyer decision: series tells you the coupling and profile direction, not the contact count. If your part string names Series III, the remaining open questions are shell style, insert arrangement and keying.
The segment that follows the series reference decides how the connector attaches to your harness or panel. For model D38999 26WG11SN the published description is an aerospace plug and socket configuration, so the cards below help you check whether that suits your mounting plan.
D38999 26WG11SN is published as a circular connector in an aerospace plug and socket configuration with a sealed, waterproof construction.
Decision: if your harness needs a mating pair for a demanding environment, this is the configuration to quote.
A fixed receptacle that mounts through a panel is chosen when the equipment side carries the connector rather than the cable.
Decision: send your panel cutout so the mounting style can be matched instead of assumed.
A jam-nut style secures from behind the panel and is often the answer where a flange will not fit the available space.
Decision: state your rear clearance and panel thickness with the inquiry.
A box-mount body suits enclosure walls where the connector terminates equipment rather than a free cable run.
Decision: describe the enclosure wall and routing space so the right body is selected.
The mounting conventions above are routing guidance, not published specifications for D38999 26WG11SN. Send your drawing and the application, and the configuration will be confirmed against the catalog with a quote.
Each row below pairs a real application context referenced for this connector with the published attribute that answers it, then states the decision to make before you send an inquiry.
The model is marketed for military applications, with vibration, shock and salt spray resistance stated.
Decision: quote with your part string, expected mating cycles and exposure written into the request.
An aerospace plug and socket configuration with high temperature resistance stated.
Decision: confirm whether the airborne side needs a free plug or a fixed panel body.
The compact circular body is described as helping keep wiring organised in dense enclosures.
Decision: check cabinet routing space and panel access before the wiring layout is finalised.
Waterproof performance and a sealed construction that helps protect the interface from corrosion and contamination.
Decision: state the moisture exposure so the sealing requirement is confirmed, not assumed.
Salt spray resistance is a stated attribute, supported by the sealed interface design.
Decision: write the corrosion exposure and service interval into the inquiry.
Vibration and shock resistance with a connection structure built for repeated mating cycles.
Decision: describe the vibration profile and service access so the right coupling is quoted.
Buyer decision: pick the row that matches your worst-case environment, then send that environment together with your part string. Send your part string and environment and the configuration will be confirmed with a quote.
Ordering for this model runs through a quote rather than a checkout, which is useful when a segment of your part string still needs confirmation. The product page states that a full range of products is in stock, that not all items are displayed, and that the model list is the reference for selection.
Include the full part string, the panel or harness drawing, and the segments you could not confirm.
Vibration, salt spray, moisture, temperature and mating cycles decide which configuration is quoted.
Share your annual or project quantity so the quote reflects the model list selection rather than a single unit.
Orders are welcome. Send your part string, quantity and application environment, and the Series III configuration will be confirmed with a quote for your project.

View productthe product page lists it as the model reference, shown as no.d38999 26wg11sn, inside the mil-dtl-38999 series iii circular connector range and describes it as an aerospace plug and socket configuration. it does not publish a full segment-by-segment decode of the characters 26, w, g11, s and n, so those positions should be confirmed with the engineering team.
vibration resistance, salt spray resistance, high temperature resistance, waterproofing and shock resistance are all stated for this model. the sealed construction is described as supporting waterproof use and helping protect the interface from corrosion and contamination.
no numeric or tabular ratings are published for this model. details such as contact count, current and voltage rating, and a temperature range in degrees should be confirmed against your requirement before a design is frozen.
series iii, the family this model belongs to, is generally associated with threaded coupling and a harsh-environment emphasis, while the other series use different coupling and profile conventions. treat the series table as general orientation and confirm the exact series requirement on your drawing.
