71-418620-01W

Overview

The Amphenol Aerospace Operations 71-418620-01W is a circular MIL-spec connector plug belonging to the MS3106 series, compliant with MIL-DTL-26482 Series I. It features an aluminum alloy shell with olive drab cadmium plating and utilizes a bayonet coupling mechanism for secure attachment. The unit contains 41 positions configured with socket contacts made of copper alloy and gold-plated for conductivity. Designed for cable mounting via solder termination, it supports a current rating of 7.5 A and a voltage rating of 600 V.

Feature Summary

• Bayonet coupling system ensures rapid connection and secure locking in vibration-prone environments
• Gold-plated copper alloy socket contacts provide reliable signal transmission and corrosion resistance
• Aluminum alloy housing with protective plating offers structural durability and environmental shielding

Applications

• Avionics systems requiring MIL-DTL-26482 compliance
• Aircraft power distribution circuits
• Instrumentation and control wiring harnesses

Procurement Notes

Verify the specific revision level of the MIL-DTL-26482 standard applicable to this part number before procurement. Confirm that the solder termination style matches your cable preparation tools and quality standards. Ensure compatibility with corresponding receptacles featuring matching bayonet coupling and pin configurations to prevent mating errors.

Selection Notes

Select this component when a straight cable-mount plug with 41 positions is required under MIL-DTL-26482 Series I specifications. The choice depends on the need for a bayonet lock rather than threaded or quick-connect interfaces. Verify that the 7.5 A current rating and 600 V voltage limits meet the circuit requirements. Consider the aluminum construction weight benefits against potential galvanic corrosion risks in specific marine or chemical environments.

Part Context

This part number falls within the Amphenol MS3106/MS3116 product family, which are widely used in military and aerospace applications. The '71-' prefix typically denotes Amphenol's commercial designation for these MIL-spec components. It represents a standard circular connector solution designed for harsh environment reliability, distinct from the higher-performance Series II or III connectors.

Replacement Considerations

Equivalent parts include MS3106F20-41S and MS3106R20-41S from other manufacturers adhering to MIL-DTL-26482 Series I. Cross-referencing should confirm identical shell size, insertion arrangement, and contact type.
