71-433034-18X

Overview

The Amphenol Aerospace Operations model 71-433034-18X is a circular connector assembly designed for high-reliability aerospace and defense applications. This specific part number denotes a receptacle configuration utilizing the MIL-DTL-26482 Series I interface standard. The housing is constructed from corrosion-resistant materials suitable for harsh environmental conditions, ensuring structural integrity under vibration and shock loads. It supports multiple contact arrangements compatible with standard pin and socket contacts, facilitating secure electrical connections in critical systems where signal integrity and mechanical durability are paramount.

Feature Summary

• Constructed to meet stringent MIL-DTL-26482 Series I environmental and mechanical standards
• Features a robust metallic or composite housing resistant to corrosive atmospheres
• Designed for secure mating with corresponding plug connectors using bayonet coupling mechanisms

Applications

• Avionics systems requiring reliable interconnects
• Military ground vehicle electronic assemblies
• Naval shipboard communication equipment

Procurement Notes

Verify the exact shell size, insert arrangement, and contact type against the official Amphenol datasheet before procurement. Ensure compatibility with existing panel cutouts and mating connector interfaces. Confirm that the specified environmental sealing requirements match the operational environment of the target application to prevent field failures due to mismatched specifications.

Selection Notes

Select this component based on verified shell size and contact configuration requirements rather than generic series compatibility. Cross-reference the specific insert code to ensure correct pinout alignment with mating hardware. Evaluate environmental sealing needs against the connector's rated IP protection level. Confirm material compatibility with surrounding structures to avoid galvanic corrosion issues in mixed-metal assemblies.

Part Context

This part belongs to the Amphenol MIL-DTL-26482 Series I family, widely used in aerospace and defense sectors. These connectors are known for their compact size and high density capabilities compared to older MIL-C-26482 designs. The series emphasizes lightweight construction without sacrificing mechanical strength, making it suitable for weight-sensitive platforms such as aircraft and satellites.

Replacement Considerations

Direct replacements must match the MIL-DTL-26482 Series I specification exactly. Verify shell size, thread type, and contact arrangement codes. Generic equivalents may lack the required environmental sealing or mechanical retention features. Consult manufacturer substitution guides for cross-brand compatibility.
