71-432653-55S

Overview

The Amphenol Aerospace Operations 71-432653-55S is a circular connector plug designed for high-reliability applications. It features a size 22 shell and utilizes a 55-position socket contact configuration. The component employs a bayonet coupling mechanism to ensure secure connection under vibration. Constructed with a corrosion-resistant metal housing, it supports robust performance in demanding environments. This specific part number identifies the plug assembly intended for panel or cable mounting within complex interconnect systems.

Feature Summary

• Bayonet coupling system for rapid engagement and secure locking
• Metal housing construction for structural integrity and durability
• High-density multi-pin contact arrangement for signal distribution

Applications

• Avionics systems
• Defense communication equipment
• Radar systems

Procurement Notes

Verify the exact mating counterpart requirements before procurement. Confirm that the receiving receptacle matches the 55-position pinout and bayonet interface specifications. Ensure environmental sealing needs are met by the complete assembly rather than the plug alone. Cross-reference the manufacturer's latest revision history to confirm compatibility with existing inventory.

Selection Notes

Select this component when a ruggedized circular connector with a bayonet lock is required. The 55-contact density suits applications needing extensive signal routing in limited space. Consider the metal housing material for electromagnetic shielding if necessary. Evaluate the operating temperature range against the specific mission profile requirements.

Part Context

This connector belongs to the broader family of military specification circular connectors used in aerospace and defense sectors. These components are engineered to withstand harsh conditions including vibration, humidity, and extreme temperatures. The design prioritizes reliability and consistent electrical performance over long service lives in critical operational scenarios.

Replacement Considerations

Direct replacements must match the MIL-DTL-38999 Series III form factor. Verify identical shell size, contact count, and coupling style. Ensure substitute parts meet the same environmental qualification standards.
