12G 2-10 Pin Aviation Circular Connector for High-Reliability Systems

GOST OHS Circular Connector with Multiple Core Count Options

12G 2-10 Pin Aviation Circular Connector Overview

The 12G 2-10 Pin Aviation Circular Connector is engineered for high-reliability signal and power transmission in aerospace, defense, and industrial environments. Its compact circular design and flexible 2-10 pin configurations provide robust electrical performance and mechanical durability for demanding applications.

Selection Guidance: Matching the Connector to Your Application

Choosing the right aviation circular connector depends on your specific electrical, mechanical, and environmental requirements. Consider the following decision points when evaluating the 12G series:

• Pin Count and Configuration: Select from 2 to 10 pins based on the number of power or signal circuits you need to connect. Confirm the required pinout and gender (male or female) for your mating cable or panel interface.
• Electrical Load: Verify that the connector's rated current and voltage meet your system's power requirements. Refer to the Technical Specifications for confirmed values.
• Environmental Exposure: Assess the operating environment for moisture, dust, vibration, and temperature extremes. The 12G connector's zinc alloy housing with nickel plating offers corrosion resistance, but confirm the IP rating and sealing options for your specific conditions.
• Mechanical Fit: Ensure the connector's mounting style and dimensions are compatible with your panel cutout or cable assembly. Provide your cable outside diameter and conductor size for proper termination planning.

Construction and Material Integrity

The 12G connector is built with a zinc alloy housing with nickel plating for structural strength and corrosion resistance. The contacts are brass plated with gold, ensuring stable conductivity and low contact resistance for reliable signal integrity over repeated mating cycles.

This rugged circular structure reduces mechanical stress on the pins and maintains consistent electrical contact during long-term operation in high-vibration environments.
