71-418620-35R

Overview

The Amphenol Aerospace Operations 71-418620-35R is a circular connector plug belonging to the MIL-DTL-26482 Series I family. It features an aluminum alloy shell with olive drab cadmium plating and utilizes a bayonet coupling mechanism for secure engagement. The assembly provides 41 positions configured with socket contacts, which are gold-plated copper alloys designed for crimp termination. This straight cable-mount plug supports a voltage rating of 600 V and current ratings up to 7.5 A or 13 A depending on contact size.

Feature Summary

• Bayonet coupling system ensures rapid and secure connection in demanding environments
• Gold-plated copper alloy contacts provide reliable signal transmission and corrosion resistance
• Aluminum alloy housing offers structural durability with protective cadmium finish

Applications

• Aviation avionics systems requiring MIL-DTL-26482 compliance
• Military ground vehicle electrical interconnections
• Industrial equipment operating in harsh environmental conditions

Procurement Notes

Verify the specific suffix codes against official Amphenol documentation to confirm exact contact arrangements and termination types. Ensure compatibility with mating receptacles regarding shell size and pin-out configurations. Confirm that the crimp tooling matches the specified contact sizes for proper installation.

Selection Notes

Select this component when a 41-position circular plug is required for MIL-DTL-26482 Series I applications. Consider the straight cable mount style and bayonet lock for installations where quick disconnect capability is necessary. Verify that the 600 V rating and current capacities meet the circuit requirements.

Part Context

This part number falls under the Amphenol 71 series, which corresponds to the MIL-DTL-26482 standard. It is functionally equivalent to other manufacturers' parts meeting the same military specifications, such as MS3116 or MS3126 series connectors with matching shell sizes and contact counts.

Replacement Considerations

Equivalent parts include MS3116F20-41S and MS3126F20-41S. Verify that substitute components maintain the same 41-position layout, socket contact type, and bayonet coupling interface to ensure mechanical and electrical interchangeability.
