71-528266-11F

Overview

The Amphenol Aerospace Operations model 71-528266-11F is a circular connector assembly designed for high-reliability applications. It features a size 11 shell constructed from aluminum alloy with an electroless nickel plating finish to ensure corrosion resistance and durability in harsh environments. The connector utilizes a bayonet coupling mechanism for rapid and secure mating, providing a positive lock that maintains integrity under vibration and shock conditions. This specific configuration includes a plug housing intended for cable termination, supporting various contact arrangements depending on the inserted contacts.

Feature Summary

• Bayonet coupling system ensures rapid connection and secure locking against vibration
• Aluminum alloy shell with electroless nickel plating provides robust environmental protection
• Designed for high-reliability aerospace and defense applications requiring durable interconnects

Applications

• Aerospace avionics systems
• Defense communication equipment
• Industrial control panels

Procurement Notes

Verify the exact contact arrangement and insertion status required for your application, as the housing alone does not include contacts. Confirm that the mating connector counterpart matches the shell size and coupling type. Ensure environmental sealing requirements are met by selecting appropriate accessories or seals if hermeticity is needed beyond the standard housing capabilities.

Selection Notes

Select this component when a ruggedized, shielded circular connector is required for critical systems. Consider the available contact types and quantities compatible with the size 11 shell. Evaluate the operating temperature range and environmental exposure to ensure the electroless nickel finish meets the specific corrosion resistance needs of the installation site.

Part Context

This part belongs to the MIL-DTL-38999 Series I family of circular connectors, which are widely used in military and aerospace industries. The series is known for its small size, light weight, and high density. The 71-series designation indicates it is manufactured by Amphenol Aerospace Operations, adhering to strict quality standards for defense and commercial aerospace markets.

Replacement Considerations

Compatible replacements must match the MIL-DTL-38999 Series I specifications, including shell size 11, bayonet coupling, and similar electrical ratings. Verify cross-reference availability from other qualified manufacturers such as Glenair or ITT Cannon, ensuring all mechanical and environmental specifications align with the original design intent.
