71-528269-37S

Overview

The 71-528269-37S is a circular connector receptacle manufactured by Amphenol Aerospace Operations. It belongs to the MIL-DTL-26482 Series I family, designed for high-density applications in harsh environments. The component features a shell size of 22 and provides 37 positions. It utilizes pin contacts with gold plating over nickel underplating for reliable signal transmission. The housing is constructed from aluminum alloy with a black chromate finish for corrosion resistance. This straight panel-mount receptacle employs a bayonet coupling mechanism for secure engagement.

Feature Summary

• Bayonet coupling system ensures rapid and secure mating cycles
• Gold-plated copper alloy contacts provide low contact resistance
• Aluminum alloy shell offers structural durability and weight efficiency

Applications

• Avionics systems
• Military communication equipment
• Radar systems

Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to confirm exact contact arrangements and environmental sealing ratings. Ensure compatibility with corresponding plug housings within the same series. Confirm that the intended application environment aligns with the specified operating temperature range and material limitations.

Selection Notes

Select this model when a high-pin-count MIL-DTL-26482 Series I receptacle is required. Compare shell sizes and contact counts against alternative series such as Series II or III if higher performance thresholds are needed. Evaluate mounting constraints to ensure the straight panel-mount style fits the enclosure design without interference.

Part Context

This part is part of Amphenol's extensive portfolio of aerospace interconnect solutions. The 71-528269-37S designation follows the internal numbering convention often associated with legacy or specific military contract lines.
