71-433035-55W

Overview

The Amphenol Aerospace Operations model 71-433035-55W is a circular connector component designed for high-reliability aerospace and defense applications. This specific part number denotes a receptacle assembly featuring a robust metal shell construction, typically utilizing MIL-DTL-38999 Series III or similar ruggedized standards to ensure environmental sealing and mechanical durability. The connector integrates precise pin-and-sleeve arrangements compatible with specified contact configurations, ensuring secure mating in demanding operational environments characterized by vibration, shock, and extreme temperature fluctuations.

Feature Summary

• Engineered with a ruggedized metal housing to withstand severe mechanical stress and environmental exposure
• Provides reliable electrical connectivity through precision-machined internal interfaces and secure locking mechanisms
• Designed for integration into complex avionics and military systems requiring high-density signal transmission

Applications

• Avionics systems in military aircraft
• Radar and communication equipment installations
• Ground support equipment requiring durable interconnects

Procurement Notes

Verify the exact contact configuration and shell size against the engineering drawing before procurement. Ensure compatibility with existing cable assemblies and mating connectors. Confirm that the supplier provides traceable documentation meeting military specifications. Check for any specific ordering suffixes that may alter material composition or plating finishes. Validate environmental ratings against project requirements.

Selection Notes

Select this component based on its specific shell size and contact arrangement requirements. Evaluate the need for environmental sealing capabilities such as IP ratings. Consider the operating temperature range and vibration resistance necessary for the target application. Ensure the chosen variant matches the interface standards of the host system. Verify availability of compatible accessories like backshells and strain reliefs.

Part Context

This part belongs to the broader family of circular connectors utilized in critical infrastructure where failure is not an option. It represents a standard solution for interconnecting electronic modules within constrained spaces. The design prioritizes longevity and consistent performance under harsh conditions, distinguishing it from commercial-grade alternatives. Its widespread adoption stems from adherence to stringent industry standards for reliability and interoperability.

Replacement Considerations

Direct replacements must match the original shell size, thread type, and contact layout exactly. Cross-reference with equivalent MIL-DTL-38999 series components from other qualified manufacturers. Verify that substitute parts meet the same environmental and mechanical qualification standards. Ensure that any alternative maintains the same polarity and keying features to prevent incorrect mating.
