71-529701-44T

Overview

The Amphenol Aerospace Operations model 71-529701-44T is a circular connector component designed for rugged military and aerospace applications. It features a plug configuration with male pin contacts, utilizing a crimp termination method for reliable electrical connections. The housing is constructed from aluminum alloy with a non-electrolytic nickel surface finish, providing durability in harsh environments. This connector complies with MIL-DTL-38999 Series I standards, ensuring compatibility with established defense interconnect systems. It supports high-density wiring configurations suitable for avionics and communication equipment.

Feature Summary

• Complies with MIL-DTL-38999 Series I specifications for standardized military interface
• Features a robust aluminum alloy housing with non-electrolytic nickel plating for corrosion resistance
• Utilizes crimp termination technology to ensure secure contact attachment under vibration
• Designed for free-hanging installation to support flexible cable routing in complex assemblies

Applications

• Avionics systems requiring reliable signal transmission in aircraft
• Military communication equipment operating in harsh environmental conditions
• Radar systems needing durable interconnect solutions
• Defense ground vehicles and missile systems

Procurement Notes

Verify the specific shell size and contact arrangement against the official Amphenol datasheet to ensure mechanical fit. Confirm that the crimp tooling matches the contact type specified in the component documentation. Check for any recent manufacturing location changes or material substitutions that may affect compliance with original MIL-DTL-38999 requirements before finalizing procurement orders.

Selection Notes

Select this connector when a Series I circular interface is required for free-hanging applications. Ensure the mating connector shares the same shell size and gender configuration. Verify that the operating temperature range and current ratings meet the system's electrical demands. Consider the non-electrolytic nickel finish for environments where moderate corrosion resistance is sufficient without heavy salt spray exposure.

Part Context

This part belongs to the broader family of MIL-DTL-38999 connectors, which are widely used in defense and aerospace industries. The Series I designation indicates a specific flange mounting style and coupling nut mechanism. Amphenol Aerospace Operations manufactures these components to meet stringent military quality standards, ensuring interchangeability with other qualified suppliers within the same specification framework.

Replacement Considerations

Compatible substitutes include equivalent MIL-DTL-38999 Series I connectors from other qualified manufacturers such as Glenair or ITT Cannon, provided they match the exact shell size, contact position, and termination type. Verify that any replacement part maintains the same environmental sealing and performance characteristics.
