71-433034-18T

Overview

The Amphenol Aerospace Operations model 71-433034-18T is a circular MIL-spec connector belonging to the MS3106 series. It functions as a wall-mount receptacle with a bayonet coupling mechanism. The component features an aluminum alloy shell finished with electroless nickel plating for corrosion resistance. It accommodates size 18 contacts and provides 12 positions arranged in a 12-12 configuration. The design supports crimp termination for reliable electrical connections in demanding environments.

Feature Summary

• Bayonet locking system ensures secure mating and vibration resistance
• Wall-mount installation style facilitates direct panel integration
• Electroless nickel plated aluminum alloy housing provides durability

Applications

• Avionics systems
• Military ground equipment
• Radar installations

Procurement Notes

Verify the specific contact type (socket or pin) required for the application, as the receptacle housing alone does not define the internal termination. Confirm that the selected cable assembly matches the specified size 18 contact dimensions. Ensure compatibility with existing MS3106 series mating plugs to maintain seal integrity and mechanical alignment within the system architecture.

Selection Notes

Select this component when a robust circular interface is needed for panel mounting applications. The bayonet style offers faster engagement compared to screw-thread variants. Consider the environmental sealing requirements of the mating plug to ensure overall system protection ratings are met during operation in harsh conditions.

Part Context

This part belongs to the MS3106 family of circular connectors, widely used in defense and aerospace sectors. These connectors are designed to meet stringent military standards for performance and reliability. The series is known for its standardized dimensions and interchangeability across various manufacturers producing compliant hardware.

Replacement Considerations

Compatible substitutes include equivalent MIL-DTL-26482 Series I connectors from other qualified manufacturers. Verify that alternative sources adhere to the same dimensional and material specifications to ensure seamless integration without redesign.
