71-418624-29E

Overview

The Amphenol Aerospace Operations model 71-418624-29E is a circular MIL-spec connector plug designed for high-reliability applications. It features a threaded coupling mechanism and an aluminum alloy shell with olive drab cadmium plating. The assembly utilizes crimp termination for secure wire attachment and includes gold-plated contacts to ensure low resistance and corrosion resistance. Rated for 600 VAC and 850 VDC, this component supports a wide operating temperature range from -65°C to 200°C. It complies with MIL-DTL-38999 Series III standards, providing environmental sealing and shielding capabilities essential for harsh operational conditions.

Feature Summary

• Threaded coupling design ensures secure connection in high-vibration environments
• Aluminum alloy housing provides structural integrity and electromagnetic shielding
• Gold-plated contacts maintain signal integrity and resist oxidation
• Crimp termination method allows for reliable field assembly and maintenance

Applications

• Avionics systems in military aircraft
• Radar and communication equipment enclosures
• Industrial control panels requiring environmental sealing
• Test and measurement instrumentation interfaces

Procurement Notes

Verify the specific series designation and contact arrangement against the official datasheet before procurement. Confirm that the ordering suffix matches the required pinout and termination style. Ensure compatibility with mating receptacles regarding shell size and thread type. Check for any updated revision levels or alternate part numbers issued by the manufacturer. Validate environmental ratings against the specific operational requirements of the target application.

Selection Notes

Select this component when MIL-DTL-38999 Series III compliance is mandatory for the project. Choose this model for applications requiring robust shielding and environmental protection against moisture and dust. Consider the aluminum construction for weight-sensitive installations where non-magnetic properties are not critical. Evaluate the thermal performance limits to ensure operation within the specified -65°C to 200°C range. Verify that the cable diameter and strain relief requirements align with the plug's physical dimensions.

Part Context

This connector belongs to the extensive family of miniature cylindrical connectors defined by MIL-DTL-38999. It represents the third generation of this standard, offering significant improvements in density and performance over previous iterations. The series is widely adopted across defense and aerospace sectors for its standardized interface and proven reliability. Amphenol Aerospace Operations manufactures these components to meet rigorous military specifications for durability and electrical performance.

Replacement Considerations

Compatible substitutes include MS3124E24-29P and JT06RE-24-29P variants from other qualified manufacturers. Ensure cross-compatibility by verifying shell size, thread type, and contact configuration. Check for equivalent environmental sealing ratings and material specifications. Confirm that the replacement meets the same MIL-DTL-38999 Series III certification requirements.
