D38999/26WB35PN Maximizing Signal Density in Miniature Electronic Grids
Он D38999/26WB35PN is a precision-engineered interconnect solution designed for specialized electronic grids where maximizing data throughput in restricted spaces is a primary requirement. Utilizing the size 11 aluminum alloy shell, this straight plug facilitates thirteen independent conductive channels through its high-density 11-35 insert arrangement. This layout is a critical asset for modern unmanned systems and compact avionics, where a high volume of telemetry and sensor signals must be routed through a single, lightweight interface. By housing thirteen Size 22D pin contacts in a size 11 envelope, the D38999/26WB35PN enables extreme port density while minimizing the overall mass of the cable assembly.

Tactical Environmental Defense and Shielding Conductivity
Финиш в классе “W” D38999/26WB35PN represents a high-strength aluminum 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 plug shell to act as a critical extension of the equipment ground. The plug features an internal grounding spring ring that provides 360-degree shell-to-shell conductivity upon mating, which is vital for maintaining effective EMI and RFI shielding for the thirteen internal signal lines in signal-dense environments.
Self-Locking Mechanical Integrity for High-Vibration Micro-Systems
As a Series III straight plug, the D38999/26WB35PN incorporates a triple-start threaded coupling mechanism with an integrated self-locking ratchet. This design allows for rapid and secure engagement with a single 360-degree turn of the coupling nut, providing audible and tactile confirmation that the connection is fully locked. The internal anti-decoupling device prevents the connector from loosening even when subjected to the intense harmonic vibrations and mechanical shocks common in small aircraft engine bays or high-velocity projectile electronics. This mechanical stability ensures constant electrical continuity across the thirteen-pin grid during critical flight operations or rapid maneuvers.
Precision Pin Fidelity and 11-35 Layout Stability
Within the compact size 11 housing, the D38999/26WB35PN employs thirteen Size 22D pin contacts, providing a high-fidelity interface for complex digital data streams. These pins are precision-machined from copper alloy and finished with high-grade gold plating to ensure low contact resistance and prevent surface oxidation throughout the equipment’s service life. The high-performance dielectric insert provides exceptional insulation resistance between the thirteen channels, preventing electrical crosstalk and signal leakage even in unpressurized aerospace compartments subject to rapid temperature fluctuations. This ensures a clean and reliable signal environment for advanced command and control systems.
100% Scoop-Proof Architecture and Field Maintenance Efficiency
The structural reliability of the D38999/26WB35PN is reinforced by its 100% scoop-proof shell design. This feature ensures that the thirteen pin contacts are recessed deeply enough within the plug housing to prevent any bending or damage if the mating receptacle is misaligned during the connection process. For long-term logistical support, the plug utilizes a rear-release crimp contact system, allowing technicians to install or replace individual pins using standard military-specification tools without disassembling the entire unit. This combination of physical protection and modular maintainability ensures that the D38999/26WB35PN delivers a high level of operational readiness for mission-critical digital grids.
