71-418622-32E

Overview

The 71-418622-32E is a circular MIL-spec connector plug manufactured by Amphenol Aerospace Operations. It belongs to the MIL-DTL-26482 series and features a straight cable mount style with a size 22 shell. The component utilizes a bayonet coupling mechanism and provides 32 positions for signal transmission. Contacts are designed for crimp termination, ensuring secure wire attachment. The unit is constructed from aluminum alloy housing with an olive drab cadmium finish for corrosion resistance. It supports a rated current of 7.5 amperes and operates at 600 volts. The contacts are gold-plated copper alloy, suitable for reliable performance in industrial and military environments.

Feature Summary

• Bayonet coupling system for rapid connection and secure locking
• Crimp termination method for robust electrical contact integrity
• Aluminum alloy housing with protective surface plating
• Straight cable entry configuration for streamlined routing

Applications

• Military avionics systems
• Industrial control panels
• Radar equipment interconnects
• Test and measurement instrumentation

Procurement Notes

Verify the specific insertion arrangement code against the design schematic before ordering. Confirm that the crimp tooling matches the contact size specifications. Ensure environmental sealing requirements align with the connector's IP rating if exposed to moisture or dust. Check for any updated revision levels or alternate suffixes that may affect compatibility with existing mating receptacles.

Selection Notes

Select this model when a size 22 bayonet connector is required for high-density wiring applications. Compare the 32-position count against available space constraints within the enclosure. Evaluate the crimp termination requirement against available assembly tools and labor capabilities. Consider the aluminum housing weight benefits compared to stainless steel alternatives for portable equipment.

Part Context

This part falls under the Amphenol MIL-DTL-26482 family, which defines small, lightweight circular connectors for harsh environments. The series is widely adopted in defense and aerospace sectors due to its standardized dimensions and reliable performance. The 71-series designation indicates it is a commercial version of the military specification, often sharing form and fit characteristics with the official MIL standard while potentially differing in testing protocols.

Replacement Considerations

Cross-reference with MS3126F22-32S or MS3106F22-32S for direct mechanical interchangeability. Verify pinout compatibility before substituting, as internal arrangements may vary between manufacturers. Ensure the replacement part maintains the same voltage and current ratings for safe operation.
