71-477107-35S

Overview

The Amphenol Aerospace Operations connector model 71-477107-35S is a circular connector assembly belonging to the MIL-DTL-38999 Series II family. It features an aluminum alloy shell with cadmium plating and utilizes a bayonet coupling mechanism for secure attachment. The component is designed as a receptacle with socket contacts, accommodating a 37-position configuration within size 14 shell dimensions. Termination is achieved through crimping methods, ensuring reliable electrical connections in demanding environments.

Feature Summary

• Bayonet locking system provides rapid and secure mating cycles
• Crimp termination ensures robust mechanical and electrical stability
• Aluminum alloy housing offers structural durability and lightweight performance

Applications

• Aviation systems requiring MIL-DTL-38999 compliance
• Marine navigation and communication equipment
