71-430577-06P

Overview

The Amphenol Aerospace Operations model 71-430577-06P is a circular MIL-DTL-38999 Series III connector designed for demanding aerospace and defense applications. It features a size 6 shell with a straight plug configuration and bayonet coupling mechanism. The unit utilizes a metallic shell, typically aluminum alloy, finished in cadmium or alternative corrosion-resistant coatings. This component supports high-density pin contacts arranged in specific insertion configurations to ensure reliable signal transmission under severe environmental conditions including vibration and temperature extremes.

Feature Summary

• Bayonet coupling system provides rapid engagement and secure retention against vibration
• MIL-DTL-38999 Series III compliance ensures compatibility with standard military interfaces
• Metallic shell construction offers robust mechanical protection and electromagnetic shielding

Applications

• Avionics systems in commercial and military aircraft
• Radar and electronic warfare equipment
• Missile guidance and control subsystems
• Ground-based military communication networks

Procurement Notes

Verify the specific contact arrangement and shell finish against project requirements before ordering. Confirm that the bayonet coupling style matches existing panel cutouts and mating receptacles. Ensure the selected variant meets the required environmental sealing standards for the intended operational zone. Cross-reference the manufacturer part number with official distribution channels to avoid counterfeit components.

Selection Notes

Select this connector when a compact, high-reliability interface is required for space-constrained avionics bays. The size 6 shell balances contact density with physical footprint. Evaluate the need for metallic versus composite shells based on weight constraints and shielding requirements. Ensure mating connectors share the identical series designation and coupling method for proper assembly.

Part Context

This component belongs to the extensive family of MIL-DTL-38999 connectors manufactured by Amphenol Aerospace. These connectors are industry standards for high-performance interconnects in harsh environments. The Series III designation indicates a specific shell style and coupling mechanism distinct from earlier generations. This part represents a critical node in complex wiring harnesses where signal integrity is paramount.

Replacement Considerations

Compatible substitutes include equivalent parts from other manufacturers meeting MIL-DTL-38999 Series III specifications. Verify dimensional interchangeability and electrical ratings before substitution. Ensure the replacement part maintains the same bayonet coupling style and shell size for direct fitment without adapter modifications.
