Backplane Connectors - ARINC

1. Overview

ARINC backplane connectors are specialized electrical components designed to meet aerospace industry standards set by Aeronautical Radio Inc. (ARINC). Defined by specifications such as ARINC 404 and ARINC 600, these connectors ensure reliable signal transmission in harsh environments. Their modular design and robust mechanical performance make them critical for avionics systems requiring high reliability, including flight control systems, radar equipment, and in-flight communication infrastructure.

2. Major Types and Functional Classification

Type	Functional Features	Application Examples
ARINC 404 Series	Standardized rectangular module design, supports up to 100 contacts	Legacy aircraft avionics systems
ARINC 600 Series	Enhanced thermal management, 360 EMI shielding	Modern commercial aircraft (e.g., Boeing 787)
ARINC 800 Series	High-speed data transmission (10+ Gbps), fiber optic options	Next-generation radar systems

3. Structure and Components

Typical ARINC backplane connectors consist of: - Modular housing with MIL-DTL-38999 series III compatibility - Gold-plated copper alloy contacts (0.76-2.8 m plating thickness) - Thermoplastic insulation with UL94 V-0 flammability rating - Aluminum alloy shell with chromate conversion coating - Integrated polarization keys and secondary locking mechanisms

4. Key Technical Specifications

Parameter	Typical Value	Importance
Contact Resistance	5m	Ensures signal integrity
Insulation Resistance	5000M	Prevents leakage currents
Operating Temperature	-65 C to +150 C	Survives extreme environments
Current Capacity	1.5A per contact	Supports power distribution
IP Rating	IP67	Dust/water ingress protection

5. Application Areas

Primary industries include: - Aerospace: Flight management computers, weather radar systems - Defense: Tactical communication systems, missile guidance units - Industrial: High-reliability automation controllers - Transportation: High-speed train control systems

6. Leading Manufacturers and Products

Manufacturer	Representative Product	Key Feature
TE Connectivity	ARINC 600-2L	Liquid cooling integration
Amphenol Aerospace	AS7975-600	Space-saving stacked design
Delphi Connection Systems	D800-12F	Hybrid power/signal transmission

7. Selection Guidelines

Key considerations: 1. Environmental requirements (temperature, vibration levels) 2. Signal type (power/data/coaxial combination) 3. Mechanical mating cycles (typically 500+ required) 4. EMI shielding effectiveness ( 60dB at 1GHz) 5. Compliance with DO-160 standards Example: For airborne SATCOM systems, select ARINC 600 connectors with integrated EMI gaskets and fiber optic modules.

8. Industry Trends

Emerging developments: - Integration of optical interfaces (ARINC 810 standard) - Nanocoatings for corrosion resistance - Smart connectors with embedded health monitoring - Increased use of composite materials - Higher speed protocols (100Gbps+ backplane channels)
