71-477102-35P

Overview

The Amphenol Aerospace Operations 71-477102-35P is a circular plug connector designed for MIL-DTL-26482 Series II applications. It features a 35-position arrangement with socket contacts, utilizing a bayonet coupling mechanism for secure engagement. The housing is constructed from aluminum alloy with an olive drab cadmium finish, providing corrosion resistance and durability in harsh environments. This cable-mount receptacle supports crimp termination for reliable electrical connections.

Feature Summary

• Bayonet coupling system ensures rapid connection and secure locking under vibration
• Aluminum alloy housing provides structural integrity and environmental protection
• Gold-plated copper alloy contacts ensure low contact resistance and signal reliability

Applications

• Military ground vehicle interconnect systems
• Avionics and flight control wiring harnesses
• Naval ship surface and submarine communication arrays

Procurement Notes

Verify the specific insertion arrangement and shell size against the design drawing to ensure compatibility with mating connectors. Confirm that the crimp tooling matches the contact size requirements specified in the manufacturer's datasheet. Check for any special handling or storage conditions required for the gold-plated contacts to prevent oxidation prior to installation.

Selection Notes

Select this component when a robust, MIL-SPEC circular connector is required for cable-mounted installations. Ensure the mating connector shares the same series, shell size, and gender specifications. Consider the operating temperature range and environmental sealing requirements of the application to confirm suitability for the intended operational environment.

Part Context

This part belongs to the MIL-DTL-26482 Series II family of circular connectors, widely used in defense and aerospace sectors. The series is known for its high-density pin-and-socket configurations and ruggedized performance standards. Amphenol Aerospace manufactures these components to meet stringent military reliability criteria for critical mission systems.

Replacement Considerations

Cross-reference with MS3471L series equivalents for direct fitment. Verify that substitute parts maintain identical shell size, position count, and contact type to ensure mechanical and electrical interchangeability without redesigning the mounting interface.
