Product Overview
The MS3476W12-8PN is a bayonet-coupled circular connector built to MIL-DTL-26482 Series II, engineered for reliable performance in extreme-environment applications. Widely used in military aeronautics, ground defense systems, industrial equipment, and marine/offshore installations, this connector series is valued for quick-disconnect coupling and dependable sealing under vibration, moisture, and temperature extremes.
This part number designates a shell size 12 connector with an 8-position insert arrangement in a pin (P) configuration, cable-mount straight plug style. The MS3476 series construction features a quarter-turn bayonet coupling mechanism for fast, secure mating, environmental sealing to protect against moisture and contaminant ingress, and finish options — including Olive Drab Cadmium and RoHS-compliant Zinc-Nickel platings — for corrosion resistance across demanding operating conditions.
Part Number Breakdown
Stock & Availability
In Stock / Factory Lead Time
The MS3476W12-8PN is part of the extensive MIL-DTL-26482 Series II platform, which is engineered for maximum versatility across complex system architectures. We understand that your designs require consistency; therefore, our connector solutions are available in a comprehensive range of shell sizes to ensure an exact mechanical fit for every application.
- Full Spectrum of Sizes: While the MS3476W12-8PN represents a specific configuration, the wider Series II product line is available in shell sizes ranging from 08 to 24. This allows engineers to scale their designs—from compact sensor interfaces to high-density power and data modules—without compromising on reliability.
- Universal Interface Standards: Every shell size within this series adheres to the identical quarter-turn bayonet coupling mechanism. This ensures that mating procedures, anti-decoupling protocols, and tooling requirements remain uniform across your entire hardware assembly, simplifying your installation and maintenance processes.
- Precision Engineering: Regardless of the shell size chosen, each unit is manufactured to stringent military-grade tolerances. Our components undergo rigorous testing for environmental stress, including high-vibration exposure and extreme temperature cycling, ensuring that your system maintains peak signal integrity across all deployment sizes.
Note: I updated “triple-start threaded coupling” to “quarter-turn bayonet coupling” and adjusted the shell size range, since MIL-DTL-26482 Series II uses bayonet coupling rather than the Tri-Start threading of MIL-DTL-38999 Series III — worth double-checking the exact shell size range (08–24) against your own product catalog before publishing.

Custom configurations supported
At AVIA Electronics, we recognize that off-the-shelf components may not always meet the unique demands of your high-performance systems. While the MS3476W12-8PN represents our standard high-reliability configuration, we offer extensive support for custom engineering to ensure our products integrate perfectly into your specific design architecture.
- Bespoke Pin & Insert Arrangements: If your project requires a non-standard contact layout or a specific mix of power and signal pins, we can facilitate custom insert arrangements that maintain the stringent MIL-DTL-26482 performance standards while meeting your exact electrical needs.
- Specialized Plating & Material Options: Beyond the standard olive drab cadmium and passivated finishes, we support custom material selections—including specialized platings for enhanced corrosion resistance, EMI shielding, or weight reduction—to survive the harshest operational theaters.
- Modified Shell Geometries: For space-constrained installations, we assist in sourcing or coordinating the manufacture of modified shell geometries, including custom mounting flanges, extended barrels, or integrated backshell configurations that reduce assembly complexity.
- Turnkey Kitting & Integration: We offer custom kitting services where we package the MS3476W12-8PN with application-specific accessories—such as heat-shrink boots, protective covers, or custom-terminated cable assemblies—ready for immediate integration into your production line.
Sample Policy & Flexible Order Support
At AVIA Electronics, we provide premium, high-reliability interconnect solutions. To ensure the performance of the MS3476W12-8PN meets your precise engineering requirements, we offer a professional sampling service. We are committed to supporting innovation at every stage of your product lifecycle.
Sample Availability: We provide samples of the MS3476W12-8PN for engineering qualification and prototype testing. As these are high-performance military-grade components, a nominal sample fee applies to cover the material cost and individual handling. This ensures that you receive verified, defect-free parts that are representative of your final production batch.
No Minimum Order Quantity (No MOQ): We believe in supporting innovation regardless of scale. Whether you need a single unit for a critical repair or a small pilot batch for system integration, we operate with no minimum order quantity. You have the flexibility to procure exactly what your current phase requires without the burden of overstocking.
Streamlined Fulfillment: Our logistics team treats every sample order with the same rigor as bulk shipments. From the moment your sample request is processed, we ensure secure, industrial-grade packaging and rapid dispatch, helping you maintain your project momentum.
