71-418622-32X

Overview

The Amphenol Aerospace Operations model 71-418622-32X is a circular connector assembly designed for high-reliability applications. It features a robust metal shell construction, typically utilizing aluminum alloy or stainless steel, to provide mechanical strength and electromagnetic interference shielding. The connector incorporates a threaded coupling mechanism to ensure secure mating under vibration and shock conditions. Internal contacts are arranged in a specific pin configuration compatible with the 32-shell size standard, supporting various contact types including solder cup or crimp terminations depending on the specific variant.

Feature Summary

• Threaded coupling interface for secure connection retention
• Metal shell construction providing structural integrity and shielding
• Compatible with standard MIL-DTL-38999 series III dimensions

Applications

• Avionics systems requiring reliable signal transmission
• Military ground equipment subject to harsh environmental conditions
• Industrial control panels needing vibration-resistant connections

Procurement Notes

Verify the exact suffix codes against the manufacturer's current datasheet to confirm contact arrangement, plating material, and termination type. Ensure compatibility with existing panel cutouts and mating receptacle specifications before procurement. Cross-reference part numbers with official Amphenol Aerospace documentation to avoid substitution errors due to minor manufacturing updates.

Selection Notes

Select this component based on required shell size, contact count, and environmental sealing needs. Confirm that the operating temperature range and voltage ratings meet system specifications. Evaluate the necessity for EMI shielding and verify that the mounting style aligns with the chassis design constraints of the final assembly.

Part Context

This part belongs to the Amphenol Series 71 family, which adheres to MIL-DTL-38999 standards. These connectors are engineered for aerospace and defense sectors where performance under extreme stress is critical. The 32-shell size indicates a larger form factor suitable for higher pin counts and power applications within the circular connector classification.

Replacement Considerations

Direct replacements must match the MIL-DTL-38999 Series III interface dimensions. Verify equivalent part numbers from other qualified manufacturers such as Glenair or ITT Cannon that share identical shell sizes and contact configurations. Ensure substitute components maintain the same environmental protection ratings and material certifications.
