71-432478-08S

Overview

The 71-432478-08S is a circular MIL-spec connector plug manufactured by Amphenol Aerospace. It features an aluminum shell with cadmium plating and bayonet coupling. The component provides 8 positions using pin contacts with gold plating, designed for crimp termination. It complies with MIL-DTL-38999 Series II standards and supports cable mounting in a straight orientation.

Feature Summary

• Bayonet locking mechanism ensures secure mating
• Crimp termination facilitates reliable wire attachment
• Gold-plated contacts enhance conductivity

Applications

• Military avionics systems
• Aerospace electronic equipment
• Ruggedized industrial control interfaces

Procurement Notes

Verify the specific datasheet revision to confirm environmental sealing ratings and contact material specifications. Ensure compatibility with existing MIL-DTL-38999 Series II receptacles. Confirm that the bayonet coupling style matches the installation requirements for the target chassis or panel.

Selection Notes

Select this model when a shielded, high-density circular connector is required for harsh environments. The aluminum construction offers durability while maintaining lightweight characteristics. Verify that the 8-position count aligns with signal routing needs and that the crimp termination method suits the available wiring harness tools.

Part Context

This part belongs to the Amphenol 71 series of circular connectors, which are widely used in defense applications. The series is known for its compliance with stringent military standards, providing robust performance in vibration and temperature extremes common in aerospace operations.

Replacement Considerations

Cross-reference with MS27473T24P8S or similar MIL-DTL-38999 Series II equivalents. Verify that substitute parts maintain the same shell size, contact arrangement, and coupling interface to ensure mechanical interchangeability without modification.
