71-419751-32S

Overview

The Amphenol Aerospace Operations model 71-419751-32S is a circular MIL-spec connector receptacle designed for panel installation. It features a straight mounting style with a jam nut attachment method. The housing is constructed from aluminum alloy and finished with an olive drab cadmium plating to ensure environmental resistance. This component utilizes a crimp termination technique for its contacts, which are made of copper alloy and plated with gold. The connector supports a specific pin count configuration suitable for twinax applications.

Feature Summary

• Constructed with an aluminum alloy shell featuring olive drab cadmium surface treatment for corrosion resistance
• Utilizes a crimp termination method with gold-plated copper alloy contacts for reliable signal transmission
• Designed for panel mount installation using a jam nut securing mechanism in a straight orientation

Applications

• Avionics systems requiring MIL-DTL-22992 compliance
• Military communication equipment interfaces
• Radar system signal distribution panels
• Test and measurement instrument rear panels

Procurement Notes

Verify the exact contact arrangement and gender against the official datasheet before procurement. Confirm that the required contacts are ordered separately as they are not included with the receptacle shell. Ensure the crimp tooling matches the specified contact size for proper termination. Check for any specific environmental sealing requirements if operating in harsh conditions beyond standard MIL specifications.

Selection Notes

Select this component when a MIL-DTL-22992 compliant receptacle is required for panel mounting. Choose this model over Series III connectors if the application specifically mandates the Series II interface standards. Consider the aluminum construction and cadmium finish for weight-sensitive military platforms. Verify that the straight jam nut configuration fits within the available chassis depth constraints.

Part Context

This part belongs to the broader family of Amphenol circular MIL-spec connectors, specifically adhering to the MIL-DTL-22992 standard. It serves as a critical interconnect solution for defense and aerospace sectors where standardized rugged connectivity is mandatory. The series provides compatibility with various mating plugs and sockets across different industrial and military supply chains.

Replacement Considerations

Equivalent parts may include MS27467 variants or other manufacturers producing MIL-DTL-22992 compatible receptacles. Ensure cross-compatibility regarding the shell size, contact arrangement, and mounting dimensions before substituting. Verify that alternative sources meet the same material and plating specifications for environmental performance.
