71-528262-13R

Overview

The Amphenol Aerospace Operations 71-528262-13R is a circular MIL-specification receptacle connector designed for high-reliability interconnect applications. This component features a bayonet coupling mechanism and an in-line cable mount installation style, ensuring secure connections in demanding environments. The housing is constructed from aluminum with a nickel plating finish to provide corrosion resistance and structural integrity. It utilizes crimp termination for the contacts, which are made of copper alloy and gold-plated to ensure low contact resistance and reliable signal transmission. The connector supports a voltage rating of 600 V and a current rating of 7.5 A, making it suitable for various aerospace and industrial power and signal distribution needs.

Feature Summary

• Bayonet coupling mechanism provides rapid and secure mating and unmating capabilities.
• Aluminum housing with nickel plating offers durability and environmental protection.
• Crimp termination ensures robust electrical connections with gold-plated copper alloy contacts.

Applications

• Aerospace avionics systems
• Military communication equipment
• Industrial control panels

Procurement Notes

Verify the specific suffix codes against official Amphenol datasheets to confirm exact contact arrangements and environmental sealing ratings. Ensure compatibility with existing panel cutouts and cable diameters before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by your project specifications.

Selection Notes

Select this model when a straight, in-line cable receptacle with a bayonet lock is required. Consider the shell size and contact count to match the wiring harness requirements. Evaluate the operating temperature range and environmental exposure to ensure the aluminum housing and plating meet the application's durability standards. Verify that the crimp tooling matches the specified contact sizes.

Part Context

This part belongs to the Amphenol MIL-DTL-26482 Series I connector family, widely used in military and aerospace sectors. These connectors are known for their compact size and high density compared to older MIL-C-5015 designs. The 71-series designation typically indicates a specific configuration within the broader Mil-26482 product line, emphasizing reliability in harsh conditions.

Replacement Considerations

Direct replacements must adhere to MIL-DTL-26482 specifications. Check for equivalent parts from other manufacturers such as Glenair or ITT Cannon that offer compatible bayonet coupling and pin/socket configurations. Ensure mechanical dimensions and electrical ratings match exactly to maintain system integrity.
