D38999/20WE6PN Robust Power Distribution with 17-06 Contact Layout
Он D38999/20WE6PN is precision-engineered for specialized electronic grids that prioritize current-carrying capacity over extreme contact density. Utilizing the size 17 aluminum alloy shell, this receptacle facilitates six independent conductive channels through its 17-06 insert arrangement. Unlike high-density signal connectors, this model features Size 12 pin contacts, which are significantly larger and capable of handling substantial electrical loads. This makes the D38999/20WE6PN an ideal choice for localized power distribution units, actuator control systems, and heavy-duty sensor arrays where maintaining low electrical resistance under load is a critical performance requirement.

Тактическая устойчивость к воздействию окружающей среды и проводимость
The “W” class finish of the D38999/20WE6PN consists of an olive drab cadmium plating applied over an electroless nickel underplate, providing a dual-layer defense against atmospheric degradation. This finish is specifically designed for the most aggressive field environments, offering an exceptional 500-hour salt spray rating. Beyond its superior corrosion resistance, the cadmium layer is highly conductive, ensuring the shell provides an effective ground path for electromagnetic interference (EMI) shielding. This ensures that the six power or signal lines remain isolated from external radio frequency interference, even in unpressurized aerospace compartments or maritime tactical zones.
Universal N-Keying and Integration Security
The D38999/20WE6PN utilizes the standard “N” (Normal) polarization keyway, ensuring maximum intermateability with any standard-issue Серия III plug of the same size and layout. This universal indexing configuration simplifies procurement and logistics for global defense and aerospace projects, as it avoids the complexities of managing alternate keyway stock. The Type 20 square flange design allows for a permanent and secure four-point mounting on equipment bulkheads. This structural stability ensures that the receptacle remains perfectly aligned during mating, protecting the six large pin contacts from the mechanical stress and potential bending that can occur in high-torque industrial environments.
Triple-Start Threaded Locking for Severe Vibration
As a Series III interconnect, the D38999/20WE6PN features a triple-start threaded coupling mechanism that is inherently self-locking. This mechanical design is intended for environments subject to high-frequency vibration and severe mechanical shock, such as those found on armored ground vehicles or near jet engine firewalls. The quick-coupling threads ensure a full and secure mate with only one full turn of the coupling nut, providing a tactile and visual confirmation of engagement. This ensuring that the electrical grid remains uninterrupted even under harmonic stress, preventing the intermittent connectivity issues common with lower-specification commercial connectors.
Mechanical Longevity and Field Serviceability
The structural reliability of the D38999/20WE6PN is further enhanced by its 100% scoop-proof shell design. This feature ensures that the six pin contacts are recessed deeply enough within the housing to prevent any damage if the mating plug is accidentally tilted or misaligned during the connection process. For long-term field support, the receptacle utilizes a rear-release crimp contact system, allowing technicians to install or replace individual pins using standard military-grade tools without disassembling the entire panel mount. This combination of physical protection and serviceability ensures the D38999/20WE6PN remains a cost-effective and durable solution for mission-critical electronic grids.
