71-477103-08S

Overview

The Amphenol Aerospace Operations 71-477103-08S is a circular MIL-Spec connector belonging to the MS3106 series, compliant with MIL-DTL-5015 standards. It features an 8-position socket configuration with a bayonet coupling mechanism and straight cable mount installation style. The unit utilizes crimp termination for reliable electrical connections and includes gold-plated contacts made from copper alloy. Designed for harsh environments, it operates within a temperature range of -65°C to 200°C and provides environmental sealing capabilities.

Feature Summary

• Bayonet locking mechanism ensures secure mating in high-vibration conditions
• Crimp termination supports robust wire-to-cable interconnections
• Gold-plated copper alloy contacts provide corrosion resistance and low contact resistance
• Environmental sealing protects internal components against moisture and contaminants

Applications

• Military avionics systems
• Aerospace ground support equipment
• Ruggedized industrial control panels
• Marine navigation instrumentation

Procurement Notes

Verify that the specific suffix matches the required contact arrangement and shell finish. Confirm compliance with current military specifications rather than obsolete commercial equivalents. Request material certification documents to ensure traceability of raw materials. Validate that the supplier is an authorized distributor to guarantee authenticity. Check for any special handling requirements due to the sensitive nature of precision connectors.

Selection Notes

Evaluate the mechanical interface requirements against the bayonet coupling style to ensure compatibility with existing housings. Assess the thermal environment to confirm suitability for the specified operating temperature range. Determine if the straight cable mount orientation fits the spatial constraints of the assembly. Verify that the crimp tooling available matches the contact size specifications for proper termination.

Part Context

This component belongs to the MS3106 family of circular connectors, which are widely recognized for their durability in demanding applications. The series is characterized by its bayonet lock design and environmental sealing properties. It serves as a standard solution for connecting cables to receptacles in sectors requiring high reliability and consistent performance under stress.

Replacement Considerations

Compatible substitutes include MS3106E18S-8S and MS3106F18S-8S, provided the mounting style and contact type align with system requirements. Ensure that any replacement part maintains the same MIL-DTL-5015 compliance level. Cross-reference the pinout arrangement to prevent wiring errors during installation.
