71-419746-02P

Overview

The Amphenol Aerospace Operations 71-419746-02P is a circular plug connector designed for robust interconnect applications. It features a bayonet coupling mechanism and is constructed with an aluminum shell that has a nickel plating finish. The unit accommodates 41 positions using socket-type contacts made of copper alloy, which are gold-plated to ensure reliable signal transmission. Designed in accordance with MIL-DTL-26482 Series II specifications, this component supports crimp termination methods for secure wire attachment. It is rated for a current capacity of 7.5 A and operates at a voltage rating of 600 V. The connector utilizes a straight cable mount installation style, providing a compact solution for space-constrained environments requiring high-density connectivity.

Feature Summary

• Bayonet coupling system ensures rapid connection and secure locking under vibration
• Gold-plated copper alloy contacts provide low resistance and corrosion resistance
• Aluminum housing with nickel plating offers structural durability and environmental protection

Applications

• Avionics systems in commercial and military aircraft
• Defense communication equipment
• Radar and guidance systems
• Industrial control panels requiring MIL-spec reliability

Procurement Notes

Verify the specific suffix codes against the manufacturer's latest datasheet to confirm contact arrangement and plating options. Ensure compatibility with mating receptacles regarding shell size and keying. Confirm RoHS compliance status if required by project specifications. Check for any obsolescence notices or lifecycle changes directly from Amphenol Aerospace before finalizing procurement plans.

Selection Notes

Select this model when a high-density 41-position circular connector is required for cable-mounted applications. The bayonet interface is suitable for environments where quick engagement and disengagement are necessary. Verify that the mating environment does not exceed the 600 V voltage rating or 7.5 A current limit. Consider the straight cable entry angle for routing constraints within the assembly.

Part Context

This component belongs to the MIL-DTL-26482 Series II family of circular connectors, widely used in aerospace and defense sectors. It represents a standard industrial-grade interconnect solution offering high pin counts in a compact form factor. The series is known for its ruggedness and ability to withstand harsh environmental conditions including moisture and temperature extremes.

Replacement Considerations

Direct replacements must match the MIL-DTL-26482 II specification, 41 position count, socket contacts, and bayonet coupling. Verify shell size 20 compatibility. Cross-reference with other manufacturers producing equivalent Mil-Spec connectors ensuring identical electrical and mechanical interfaces.
