71-529703-35E

Overview

The Amphenol Aerospace Operations model 71-529703-35E is a circular connector plug assembly designed for high-reliability aerospace and defense applications. This specific component features a 35-position configuration, utilizing a robust metal shell constructed from aluminum alloy with a chromate conversion coating for enhanced corrosion resistance. The interface employs a CA bayonet coupling mechanism to ensure secure mating and vibration resistance in dynamic environments. Electrical contacts are gold-plated to maintain signal integrity and low contact resistance over extended service life.

Feature Summary

• Utilizes a CA bayonet coupling system for rapid and secure connection maintenance under high-vibration conditions.
• Constructed with an aluminum alloy shell treated with chromate conversion coating for superior environmental durability.
• Features gold-plated electrical contacts to ensure reliable conductivity and minimize signal interference.

Applications

• Avionics systems requiring high-density interconnects
• Military communication equipment housings
• Radar and navigation subsystem assemblies

Procurement Notes

Verify the exact suffix codes against the manufacturer's current datasheet to confirm plating options and contact arrangements. Ensure compatibility with mating receptacles regarding shell size and coupling thread specifications. Request material certification documents to validate compliance with aerospace quality standards before final procurement approval.

Selection Notes

Select this connector based on the required pin count and environmental sealing needs. Confirm that the operating temperature range aligns with the specific mission profile. Evaluate the mechanical strain relief requirements to determine if additional cable clamps are necessary for the installation environment.

Part Context

This part belongs to the Amphenol Series 71 family of circular connectors, widely used in ruggedized electronic enclosures. The series is characterized by its standardized shell sizes and versatile contact configurations, supporting both power and signal transmission needs within compact form factors suitable for space-constrained aircraft and ground support equipment.

Replacement Considerations

Cross-reference with equivalent MIL-DTL-38999 Series I connectors for potential interchangeability. Verify dimensional tolerances and mating interface compatibility before substituting with alternative manufacturers' offerings to ensure seamless integration into existing harnesses.
