71-528267-41W

Overview

The Amphenol Aerospace Operations 71-528267-41W is a circular MIL-spec connector receptacle designed for high-reliability applications. It complies with MIL-DTL-38999 Series III standards and features a size 20 shell in a wall-mount configuration. The component utilizes a bayonet coupling mechanism for secure mating. Contacts are gold-plated copper alloy sockets, supporting crimp termination. The housing is constructed from aluminum with an olive drab cadmium finish, providing corrosion resistance. This straight-angle cable receptacle ensures robust electrical performance in demanding environments.

Feature Summary

• Complies with MIL-DTL-38999 Series III specifications for rigorous military-grade reliability
• Features a bayonet coupling system for rapid and secure connection engagement
• Utilizes gold-plated contacts to ensure low contact resistance and signal integrity
• Constructed with an aluminum alloy housing for structural durability and weight efficiency

Applications

• Avionics systems requiring certified circular interconnects
• Military aircraft wiring harnesses
• Defense electronics equipment
• Harsh environment control panels

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact contact arrangement and plating options. Ensure compatibility with corresponding plug housings within the same series. Confirm that the wall-mount installation style aligns with panel thickness requirements. Cross-reference the part number with official distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a MIL-DTL-38999 Series III compliant wall-mount receptacle is required. The size 20 shell accommodates specific pin counts suitable for moderate density applications. The gold plating is essential for maintaining reliable signal transmission in critical circuits. Verify that the bayonet lock mechanism meets the operational speed and security needs of the assembly design compared to threaded alternatives.

Part Context

This part belongs to the extensive Amphenol 38999 family of circular connectors, widely used in aerospace and defense sectors. The 71- prefix typically denotes Amphenol's internal designation for these MIL-spec components. As a Series III connector, it represents a smaller, lighter evolution of earlier designs while maintaining interface compatibility with legacy systems where applicable.

Replacement Considerations

Compatible substitutes include equivalent MIL-DTL-38999 Series III receptacles from manufacturers such as Glenair or ITT Cannon. Ensure the substitute matches the shell size, contact type, and mounting style. Verify that any alternative part maintains the same environmental sealing and coupling mechanism characteristics.
