71-528267-41T

Overview

The Amphenol Aerospace Operations 71-528267-41T is a circular MIL-spec connector receptacle belonging to the MS3471 series. It features 41 positions with socket contacts arranged in a 20-41 insertion configuration. The unit utilizes a size 20 shell in an in-line cable mount style, designed for crimp termination. Contact materials consist of copper alloy with gold plating. The assembly supports a current rating of 7.5 A and complies with MIL-DTL-26482 Series II standards.

Feature Summary

• Provides secure signal and power distribution through a robust multi-position circular interface
• Ensures reliable electrical contact via gold-plated copper alloy sockets
• Facilitates direct cable integration using a straight in-line mounting design

Applications

• Avionics systems requiring MIL-DTL-26482 compliance
• Aircraft wiring harnesses and junction modules
• Harsh environment interconnect applications

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with mating connectors. Confirm that the crimp tooling matches the specified contact size and material requirements. Check for any updated environmental certifications or material restrictions relevant to the target deployment region before finalizing procurement orders.

Selection Notes

Select this component when a 41-position cable-mount receptacle is required for MIL-DTL-26482 Series II environments. Ensure the mating connector corresponds to the MS3470 series with matching shell size and insertion arrangement. Validate that the installation space accommodates the in-line form factor and that the crimp termination process aligns with available maintenance tools.

Part Context

This part belongs to the MS3471 family of lightweight, high-density circular connectors manufactured by Amphenol Aerospace Operations. These components are engineered for commercial aerospace applications where weight reduction and simplified installation are critical. The series offers a sealed, compact alternative to heavier military-standard equivalents while maintaining performance in demanding operational conditions.

Replacement Considerations

Cross-reference with MS3471L20-41SW for equivalent specifications within the same series. Verify pin-to-pin compatibility and mating interface dimensions before substituting.
