71-528269-02S

Overview

The Amphenol Aerospace Operations 71-528269-02S is a circular MIL-spec connector plug designed for high-reliability interconnect applications. It features 61 positions with female socket contacts, utilizing a size 25 shell in a straight cable mount configuration. The component complies with MIL-DTL-38999 Series I standards and employs a bayonet coupling mechanism for secure engagement. Contacts are gold-plated copper alloy, terminated via crimping to ensure signal integrity. The aluminum housing provides structural durability while maintaining a lightweight profile suitable for aerospace environments.

Feature Summary

• Bayonet coupling system ensures rapid and secure connection retention under vibration
• Gold-plated contacts provide reliable conductivity and corrosion resistance
• Aluminum shell construction offers robust mechanical protection with weight efficiency

Applications

• Commercial aircraft avionics systems
• Military defense communication equipment
• Harsh environment instrumentation interfaces

Procurement Notes

Verify the manufacturer part number against official Amphenol documentation to confirm exact contact arrangement and plating specifications. Ensure compatibility with mating receptacles regarding shell size and coupling type. Confirm that the crimp termination method aligns with available tooling and wire gauge requirements for the specific installation.

Selection Notes

Select this component when a 61-position circular connector is required within a MIL-DTL-38999 Series I framework. The straight cable mount style suits applications where space allows linear cable exit. Verify that the operating environment temperature range and environmental sealing requirements match the standard capabilities of the series.

Part Context

This part belongs to the Amphenol 38999 Aluminum series, a widely adopted family of circular connectors used across aerospace and defense sectors. The series is characterized by its small size, light weight, and high density of contacts within a standardized shell size. It serves as a critical interconnect solution for complex electronic assemblies requiring rugged performance.

Replacement Considerations

Cross-reference with equivalent MIL-DTL-38999 Series I plugs from other manufacturers if supply constraints exist. Ensure substitute parts maintain identical shell size, contact count, and coupling interface to guarantee mechanical interchangeability without redesign.
