71-418620-02W

Overview

The Amphenol Aerospace Operations model 71-418620-02W is a circular MIL-spec connector plug designed for industrial and transportation applications. It features a straight cable-mount installation style with a size 20 shell. The component utilizes a bayonet coupling mechanism and supports 41 positions. Contacts are female sockets made of copper alloy with gold plating, rated for 7.5 A current and 600 V voltage. The termination method is crimp, ensuring reliable signal and power transmission in demanding environments.

Feature Summary

• Bayonet coupling system for secure mating
• Crimp termination for robust contact integrity
• Gold-plated copper alloy contacts for corrosion resistance

Applications

• Industrial equipment interconnects
• Transportation vehicle wiring systems
• Signal distribution panels

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct shell finish, contact arrangement, and environmental sealing ratings. Confirm that the crimp tooling matches the specified contact size requirements. Check for any updated RoHS compliance status or lifecycle notices directly from Amphenol Aerospace before finalizing procurement orders.

Selection Notes

Select this component when a size 20 circular connector with 41 positions is required. Ensure compatibility with existing panel cutouts and mating receptacles. Verify that the crimp termination type aligns with available assembly tools and wire gauge specifications. Consider the operating temperature range and environmental exposure requirements relative to the aluminum alloy shell construction.

Part Context

This part belongs to the MIL-DTL-26482 series of circular connectors, widely used in military and aerospace sectors. The 71-series designation typically indicates Amphenol's internal numbering for these standardized components. It represents a standard interface solution for high-density connections in ruggedized electronic enclosures.

Replacement Considerations

Cross-reference with MS3116F20-41S for equivalent MIL-DTL-26482 specifications. Verify shell size, contact count, and coupling style match exactly before substitution.
