D38999/24WE6SA Medium-Power Distribution in Single-Hole Jam Nut Architectures
The D38999/24WE6SA is a precision-engineered interconnect solution designed for specialized electronic grids where both current-carrying capacity and panel space conservation are essential. Utilizing the size 17 aluminum alloy shell, this receptacle facilitates six independent conductive channels through its 17-06 insert arrangement. Unlike high-density signal-only models, the 17-06 layout utilizes Size 12 socket contacts, which are designed to handle significantly higher electrical loads. The Type 24 jam nut mounting style allows for a rapid single-hole installation, making it a primary choice for decentralized power distribution units and motor control interfaces where a robust, high-current connection must be established in a confined mechanical footprint.
Key Specifications

|---|---|---|---|---|---|---|---|
Aluminum alloy | ~1000 VAC | ~23 A | -65 °C to +200 °C | IP67 | 500 | A | threaded coupling |
Tactical Environmental Shielding and Conductivity
The “W” class finish of the D38999/24WE6SA consists of an olive drab cadmium plating applied over an electroless nickel underplate, creating a multi-layered defense against atmospheric degradation. This finish is specifically certified for 500 hours of continuous salt spray exposure, ensuring the receptacle remains operational in maritime or high-humidity tactical zones. Beyond its superior corrosion resistance, the cadmium layer provides excellent surface conductivity, ensuring the shell acts as an efficient extension of the system ground. This is vital for maintaining effective EMI and RFI shielding, protecting the six internal power and signal lines from electromagnetic interference in dense electronic clusters or near high-frequency radio equipment.
Alternate A-Keying for Enhanced System Safety
The D38999/24WE6SA features the “A” polarization keyway, which is an alternate indexing configuration designed to prevent accidental cross-mating in complex panels. In environments where multiple size 17 connectors are located in close proximity, utilizing alternate keys like “A” ensures that only the correctly keyed plug can be mated with this specific receptacle. This physical lockout mechanism is a critical safety feature for engineers designing mission-critical systems, as it eliminates the risk of human error during rapid field assembly or maintenance. Combined with the triple-start threaded coupling, the “A” keying ensures a secure, verified, and vibration-resistant connection in high-stakes operational environments.
Precision Socket Fidelity and 17-06 Layout Stability
Within the size 17 housing, the D38999/24WE6SA utilizes six Size 12 socket contacts, providing a secure female interface that is highly resistant to mechanical shock and vibration. These contacts are precision-machined from copper alloy and finished with high-grade gold plating to maintain a low-resistance electrical interface throughout the equipment’s service life. The large Size 12 contact diameter provides a generous mating surface area, which is essential for maintaining electrical stability under high-current conditions. The high-performance dielectric insert ensures superior insulation resistance, preventing electrical leakage between the six channels even in unpressurized aerospace compartments subject to rapid temperature fluctuations.
Mechanical Longevity and Field Serviceability
The structural reliability of the D38999/24WE6SA is further supported by its 100% scoop-proof shell architecture. This design ensures that the six socket contacts are recessed deeply enough within the housing to prevent any damage if the mating plug is misaligned or tilted during the connection process. For long-term field support, the receptacle utilizes a rear-release crimp contact system, allowing maintenance technicians to install or replace individual sockets using standard military tools without disassembling the entire unit from the panel. This combination of physical protection and modular serviceability ensures the D38999/24WE6SA provides a durable, low-maintenance solution for ruggedized digital grids.
FAQ
How many contacts are in the D38999/24WE6SA layout?
How many contacts are in the D38999/24WE6SA layout?
