D38999/24WB35PN Efficiency of Single-Hole Jam Nut Mounting
Он D38999/24WB35PN is a precision-engineered interconnect solution designed for specialized electronic grids where minimizing panel real estate and streamlining assembly are critical requirements. Unlike the four-hole square flange models, this Type 24 jam nut receptacle requires only a single D-shaped cutout in the equipment bulkhead. This design significantly simplifies the machining process and reduces potential leak paths for moisture or dust. The use of a single high-torque hex nut for securing the connector ensures a stable, vibration-resistant mount, making it a primary choice for compact avionics enclosures and tactical communication devices where internal volume is at a premium.

Tactical Environmental Resilience and Shell Conductivity
Финиш в классе “W” D38999/24WB35PN represents a high-strength aluminum alloy housing treated with olive drab cadmium over an electroless nickel underplate. This multi-layered defense system is specifically engineered for the most aggressive field environments, providing a certified 500-hour salt spray rating. Beyond its superior corrosion resistance, the cadmium finish is highly conductive, allowing the shell to act as a critical extension of the equipment ground. This ensures high-performance EMI and RFI shielding for the thirteen internal signal lines, protecting them from electromagnetic interference in dense electronic clusters.
Universal N-Keying and Standardized Intermateability
The D38999/24WB35PN utilizes the standard “N” (Normal) polarization keyway, which is the industry-default indexing configuration for Series III connectors. This ensures maximum intermateability with any standard-issue Series III plug of the same shell size and layout, facilitating easy integration into global aerospace and defense supply chains. The triple-start threaded coupling mechanism provides a self-locking connection that is inherently resistant to loosening under severe harmonic vibration. This standardized indexing logic ensures that the D38999/24WB35PN delivers a familiar and reliable mating experience for technicians during rapid field maintenance and initial assembly cycles.
High-Density Signal Integration with 11-35 Layout
Within the compact size 11 housing, the D38999/24WB35PN employs the 11-35 insert arrangement, providing thirteen independent conductive channels using Size 22D pin contacts. These pins 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. This high-density configuration allows system designers to consolidate multiple sensor feeds and data streams into a single, compact interface. The high-performance dielectric insert provides superior insulation resistance, ensuring signal purity and preventing crosstalk even in unpressurized aerospace compartments subject to rapid temperature fluctuations.
Mechanical Protection and Reliability in the Field
The structural reliability of the D38999/24WB35PN is further enhanced by its 100% scoop-proof shell design. This feature ensures that the thirteen pin contacts are recessed deeply enough within the housing to prevent any bending or 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 pins using standard military tools without disassembling the entire unit from the panel. This combination of physical protection and modular serviceability ensures the D38999/24WB35PN provides a low total cost of ownership for mission-critical electronic grids.
