71-477101-06P

Overview

The Amphenol Aerospace Operations model 71-477101-06P is a circular MIL-DTL-38999 Series III connector. It features a size 16 shell with six signal contacts arranged in a straight plug configuration. The housing is constructed from aluminum alloy, providing structural integrity for demanding environments. Contact materials are copper alloy with gold plating to ensure reliable conductivity and corrosion resistance. The unit operates within a temperature range of -65°C to +200°C and supports up to 2000V AC voltage. It utilizes a bayonet coupling mechanism for secure mating and includes cable termination for installation.

Feature Summary

• Bayonet coupling system ensures rapid connection and secure locking under vibration
• Gold-plated copper alloy contacts provide low contact resistance and high reliability
• Aluminum alloy shell offers lightweight durability and electromagnetic shielding
• High-temperature design rated for continuous operation up to 200°C

Applications

• Military avionics systems requiring high-reliability interconnects
• Aerospace guidance and control instrumentation
• Naval shipboard electronic equipment
• Ruggedized ground vehicle communication arrays

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact contact arrangements and environmental sealing options. Ensure compatibility with existing panel cutouts and mating receptacles. Confirm that the bayonet coupling style matches the assembly requirements. Check for any restricted material listings or export control classifications associated with this military specification part number before finalizing procurement.

Selection Notes

Select this component when a Series III circular connector is required for high-temperature aerospace applications. The size 16 shell provides an optimal balance between contact density and physical footprint. Verify that the straight plug orientation fits the available cabling space. Ensure the operating environment does not exceed the specified thermal limits for the gold-plated contacts. Confirm that the bayonet lock mechanism is suitable for the intended vibration profiles.

Part Context

This part belongs to the MIL-DTL-38999 Series III family, which defines small, high-density circular connectors for severe environments. These connectors are widely used in defense and aerospace sectors due to their standardized dimensions and robust performance characteristics. The series replaces older MIL-C-26482 designs while maintaining backward compatibility with many legacy interfaces. Amphenol manufactures these units to meet strict military quality standards.
