71-528266-68E

Overview

The Amphenol Aerospace Operations part number 71-528266-68E is a circular MIL-spec connector receptacle belonging to the 38999 Aluminum series. It features an aluminum shell with nickel plating and utilizes a bayonet coupling style for secure attachment. The component is designed for wall mount installation in a straight orientation. It accommodates 68 positions using socket-type contacts that are gold-plated for reliable conductivity. The termination method specified is crimp, ensuring robust wire connections. This receptacle is engineered to meet rigorous military standards for harsh environment applications.

Feature Summary

• Bayonet coupling mechanism provides rapid and secure mating
• Gold-plated socket contacts ensure low resistance and corrosion resistance
• Aluminum alloy housing offers structural durability and weight efficiency

Applications

• Avionics systems requiring high-density interconnects
• Military communication equipment enclosures
• Radar system signal distribution panels

Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to confirm contact arrangement and environmental sealing ratings. Ensure compatibility with corresponding plug housings within the same series. Confirm that the crimp tooling matches the specified contact size for proper termination integrity during assembly processes.

Selection Notes

Select this component when a high-pin-count circular connector is required for panel mounting. The aluminum construction suits applications where weight reduction is critical without sacrificing mechanical strength. Verify that the operating voltage and current ratings align with the circuit requirements before integration into the final assembly design.

Part Context

This part belongs to the extensive 38999 series of circular connectors, widely used in aerospace and defense industries. The series is known for its interchangeability with other manufacturers' products meeting the same MIL-DTL-38999 specifications. The aluminum variant specifically targets applications demanding lightweight yet durable interconnect solutions for extreme operational conditions.

Replacement Considerations

Cross-reference with MS27468E18-68PA or similar MIL-DTL-38999 Series I equivalents. Ensure that mating dimensions and keying options match exactly to maintain interface compatibility in existing systems.
