71-528269-35R

Overview

The Amphenol Aerospace Operations part number 71-528269-35R is a circular MIL-spec connector plug. It features a shell size of 13 and utilizes insertion arrangement 13-35, providing seven positions for #20 socket contacts. The housing is constructed from aluminum with an olive drab cadmium electroless nickel plating finish. Designed for cable mounting in a straight orientation, the unit employs a self-locking coupling mechanism to ensure secure engagement. Contacts are gold-plated copper alloy crimp types rated for 5 A current.

Feature Summary

• Self-locking coupling mechanism ensures secure connection without external tools
• Aluminum shell construction provides structural integrity and weight efficiency
• Gold-plated copper alloy crimp contacts support reliable signal transmission
• Straight cable mount design facilitates direct wiring integration

Applications

• Avionics systems requiring MIL-DTL-38999 compliance
• Military communication equipment interconnects
• Aerospace control and instrumentation panels
• Harsh environment signal distribution networks

Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure traceability. Confirm that the received component matches the exact insertion arrangement and contact configuration specified in the official datasheet. Inspect the shell plating for defects and verify the integrity of the crimp terminals before installation to maintain operational reliability.

Selection Notes

Select this component when a compact, self-locking plug is required for shielded cable applications. Ensure the mating receptacle shares the identical shell size and insertion arrangement. Verify that the operating temperature range aligns with the environmental conditions of the target assembly. Consider the crimp termination style for compatible wire gauge requirements.

Part Context

This part belongs to the Amphenol 38999 Aluminum series, representing a high-density circular connector family widely used in defense and aerospace sectors. The designation corresponds to the MIL-DTL-38999 Series III standard, ensuring interchangeability with other manufacturers' components meeting the same rigorous specifications for performance and durability.

Replacement Considerations

Cross-reference with MS3452W13S35SA or equivalent MIL-DTL-38999 Series III plugs. Verify that substitute parts maintain the self-locking feature and identical contact arrangement to ensure mechanical and electrical compatibility within existing assemblies.
