71-529706-28X

Overview

The Amphenol Aerospace 71-529706-28X is a circular MIL-spec connector plug belonging to the Series III (38999) family. It features an aluminum alloy shell with an olive drab cadmium electroless finish for corrosion resistance. The unit utilizes a bayonet coupling mechanism and is designed for cable mounting. It accommodates size 28 contacts, specifically configured as a socket receptacle variant within the broader product line context.

Feature Summary

• Bayonet coupling system for rapid connection and secure locking
• Aluminum alloy shell construction providing structural durability
• Olive drab cadmium plating for environmental protection
• Cable mount design for integrated wiring applications

Applications

• Avionics systems in military aircraft
• Radar and communication equipment interconnects
• Test and measurement instrumentation
• Industrial control panels requiring MIL-DTL-38999 compliance

Procurement Notes

Verify the specific suffix code against the manufacturer's current datasheet to confirm contact arrangement and orientation. Ensure the ordering part number matches the required shell size and contact type specifications. Cross-reference the revision level to guarantee compatibility with mating connectors in existing assemblies.

Selection Notes

Select this component when a ruggedized, shielded circular connector is required for harsh environments. Confirm that the bayonet interface aligns with panel or cable constraints. Evaluate the aluminum shell weight benefits against stainless steel alternatives if extreme mechanical impact resistance is not the primary driver.

Part Context

This part belongs to the Amphenol Series III circular connector family, widely adopted in defense and aerospace sectors. It replaces legacy MS27467 style connectors while maintaining dimensional interchangeability. The series is known for high contact density and reliable performance under vibration and thermal cycling conditions.

Replacement Considerations

Direct equivalents include MS27467E28S1P and similar MIL-DTL-38999 Series III plugs. Verify that mating connectors share the same shell size and contact configuration to ensure proper engagement.
