D38999/26FF11PN Optimized Power Distribution in Mid-Size Electronic Grids
Он D38999/26FF11PN is a precision-engineered interconnect solution designed for specialized electronic grids that require a balanced integration of power and signal density. Utilizing the size 19 aluminum alloy shell, this straight plug facilitates eleven independent conductive channels through its 19-11 insert arrangement. Unlike ultra-high-density signal connectors, the 19-11 layout employs Size 16 pin contacts, which are engineered to handle higher current loads with minimal heat dissipation. This makes the D38999/26FF11PN an essential component for localized power distribution units, actuator control systems, and high-fidelity sensor arrays where electrical stability is a primary operational requirement.

Покрытие из химически осажденного никеля и превосходное подавление электромагнитных помех.
The “F” class finish of the D38999/26FF11PN consists of high-purity electroless nickel plating applied over the aluminum housing, providing a clean, durable, and highly conductive surface. This finish is specifically selected for environments where electromagnetic compatibility (EMC) is a critical design factor. The electroless nickel provides a low-impedance ground path across the shell-to-shell interface, which, combined with the plug’s internal grounding fingers, ensures 360-degree shielding effectiveness. This protects the eleven internal conductive lines from RFI and EMI, ensuring that sensitive digital telemetry remains uncorrupted in the dense electromagnetic environments typical of modern aircraft and radar platforms.
Механическая целостность и безопасность самоблокирующейся муфты
Как Серия III straight plug, the D38999/26FF11PN features a triple-start threaded coupling mechanism with an integrated self-locking ratchet system. This design facilitates a rapid and secure connection with only one full 360-degree turn of the coupling nut, providing both tactile and audible confirmation of a verified mate. The internal anti-decoupling device ensures that the connector remains locked even under the severe harmonic vibrations and mechanical shocks common in jet engine compartments or high-performance military vehicle operations. This mechanical robustness ensures constant electrical continuity across the eleven-pin grid, preventing intermittent power loss during high-stress maneuvers.
Precision Pin Fidelity and 19-11 Layout Integrity
Within the size 19 housing, the D38999/26FF11PN employs eleven Size 16 pin contacts, offering a robust and reliable interface for critical power and signal channels. These pins are precision-machined from high-conductivity copper alloy and finished with high-grade gold plating to prevent atmospheric oxidation and maintain low contact resistance throughout the equipment’s service life. The high-performance dielectric insert ensures that each of the eleven channels is electrically isolated, maintaining superior insulation resistance even under rapid pressure changes or high humidity. This ensures that the power grid remains free from electrical leakage and short circuits in unpressurized aerospace compartments.
100% Архитектура, защищенная от выкачивания грунта, и эффективность обслуживания
The structural reliability of the D38999/26FF11PN is reinforced by its 100% scoop-proof shell design, which protects the eleven pin contacts from being bent or damaged if the mating receptacle is misaligned during connection. For long-term logistical support and field repairability, the plug utilizes a rear-release crimp contact system. This allows technicians to install or replace individual pins using standard military-specification tools without disassembling the entire unit from the cable harness. This combination of physical protection and modular serviceability ensures that the D38999/26FF11PN delivers a high level of operational readiness and a low total cost of ownership for ruggedized digital environments.
