71-528267-02E

Overview

The Amphenol Aerospace Operations part number 71-528267-02E is a circular MIL-spec connector receptacle belonging to the MS27505 series. It features a size 25 aluminum shell with nickel plating and a bayonet coupling style. The unit provides 61 positions utilizing male pin contacts with gold plating, arranged in the 25-61 insertion configuration. Designed for box mount installation, it employs a crimp termination method for wire connections. This component complies with MIL-DTL-38999 Series I standards, ensuring suitability for high-density interconnect applications requiring robust environmental sealing and mechanical durability.

Feature Summary

• Bayonet coupling mechanism for rapid engagement and secure locking
• Gold-plated male pin contacts for reliable signal transmission
• Aluminum alloy housing with nickel finish for corrosion resistance
• Crimp termination interface for secure wire harness integration

Applications

• Avionics systems in commercial and military aircraft
• Radar and communication equipment enclosures
• Test and measurement instrument interfaces
• Industrial control panel wiring

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact shell size, contact arrangement, and plating specifications. Ensure that the ordering documentation explicitly references MIL-DTL-38999 Series I compliance. Confirm that the crimp tooling matches the designated contact type before procurement to guarantee proper termination quality and electrical continuity.

Selection Notes

Select this component when a high-density 61-position interface is required within a size 25 form factor. The box mount style is optimal for chassis integration where space efficiency is critical. Evaluate the bayonet coupling requirement against threaded alternatives if higher vibration resistance is needed. Verify that the aluminum material and nickel plating meet the environmental exposure criteria of the target application.

Part Context

This receptacle is part of the extensive MS27505 family produced by Amphenol Aerospace Operations. The series is widely recognized in the aerospace sector for its standardized dimensions and interchangeability. The 71-528267-02E designation specifically identifies the physical shell and contact configuration within this broader ecosystem of circular connectors.

Replacement Considerations

Cross-reference with other manufacturers offering MIL-DTL-38999 Series I compliant parts. Verify dimensional compatibility and mating interface integrity before substituting. Ensure that any alternative source meets the same environmental and performance standards as the original specification.
