8D5-19F35SN High-Density Signal Consolidation in Miniature Grids
The 8D5-19F35SN is a precision-engineered interconnect solution designed for specialized electronic grids where maximizing signal capacity in a limited spatial envelope is a primary design objective. Utilizing the size 19 aluminum alloy shell, this straight plug facilitates sixty-six independent conductive channels through its high-density 19-35 insert arrangement. This configuration is a critical asset for modern avionic suites and tactical communication hubs, where a vast number of sensor feeds and high-speed data bus signals must be consolidated into a single interface. By housing sixty-six Size 22D socket contacts, the 8D5-19F35SN allows for extreme functional integration without increasing the physical footprint of the equipment.

Electroless Nickel Finish and Conductive Shielding Integrity
The “F” class finish of the 8D5-19F35SN represents a high-purity electroless nickel plating applied over the aluminum housing, providing a clean, durable, and exceptionally conductive surface. This finish is specifically selected for electronic grids where electromagnetic interference (EMI) suppression is a non-negotiable requirement. The electroless nickel provides a low-impedance ground path across the shell-to-shell interface, which, in conjunction with the plug’s internal grounding spring, ensures 360-degree shielding effectiveness. This prevents external RFI from corrupting the sixty-six internal signal paths, ensuring that sensitive digital telemetry remains accurate in dense electromagnetic environments.
Self-Locking Mechanical Stability and Vibration Resistance
As a Series III straight plug, the 8D5-19F35SN 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 tactile and audible confirmation of a verified mate. The internal anti-decoupling device ensures that the connector remains locked even when subjected to the intense harmonic vibrations and mechanical shocks typical of jet engine compartments or high-performance armored vehicle operations. This mechanical robustness ensures constant electrical continuity across the sixty-six-pin signal grid during high-stress field maneuvers.
Precision Socket Fidelity and 19-35 Layout Integrity
Within the size 19 housing, the 8D5-19F35SN employs sixty-six Size 22D socket contacts, providing a high-fidelity female interface for precision digital and analog signals. These sockets are precision-machined from copper alloy and finished with high-grade gold plating to maintain an ultra-low-resistance electrical path throughout the equipment’s service life. The gold plating protects the contact surfaces from atmospheric oxidation and environmental degradation, even in unpressurized aerospace compartments. The high-performance dielectric insert ensures that each of the sixty-six signal paths is electrically isolated, maintaining high insulation resistance and preventing crosstalk between sensitive data lines.
100% Scoop-Proof Architecture and Maintenance Efficiency
The structural reliability of the 8D5-19F35SN is reinforced by its 100% scoop-proof shell design, which ensures that the sixty-six socket contacts are recessed deeply enough to prevent any damage if the mating plug is misaligned during the connection process. For long-term logistical support and field repairability, the plug utilizes a rear-release crimp contact system. This allows maintenance technicians to install or replace individual sockets 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 8D5-19F35SN delivers a high level of operational readiness for mission-critical digital environments.
