• High-density contact arrangements to support both power and signal lines
• Built with lightweight aluminum, stainless steel, or composite shells
• Excellent EMI shielding and environmental sealing
• Present temperature and corrosion resistance

Best Uses

• Avionics backplanes
• Engine control units (ECUs)
• Flight control systems

2. ARINC 600 Rack and Panel Connectors

Amphenol’s ARINC 600 series connectors are a standout solution for modular avionics systems. Boasting the ability to support complex architectures with room for customization and expansion, these connectors promote scalability and rapid field replacement while ensuring high-speed data transfer.

Features

• Modular inserts allow for mixed signal, power, and high-speed data configurations
• Offer low mating force and durable engagement interface
• Enable high-speed digital protocols, including Ethernet and optical signals
• Compliant with industry standards for line-replaceable units (LRUs)

Best Uses

• LRUs and avionics trays
• Communications and navigation systems
• Integrated modular avionics (IMA) platforms

3. Rectangular High-Speed Connectors (BACC65 Series)

The BACC65 series includes high-density rectangular connectors developed for digital and analog signal transmission in aircraft electronics. These components facilitate stable and shielded signal transmission, particularly in environments with high electromagnetic interference.

Features

• Built with a rugged metal shell with EMI shielding to prevent signal interference
• Available with fiber optic, coaxial, and signal terminations
• Their compact design allows for installation in space-constrained systems

Best Uses

• Flight data acquisition and recording systems
• Mission computing and telemetry units
• Communication interface modules

4. Fiber Optic Interconnect Solutions

As aircraft systems are becoming more reliant on high-bandwidth digital communication, Amphenol’s fiber optic solutions serve to enable real-time, EMI-resistant data transmission. Essential for platforms that rely on constant data for flight management and predictive maintenance, these items prioritize speed, connection integrity, and reduced weight. Some notable options include:

• TFOCA-II® Connectors: Ideal for harsh environments, TFOCA-II® connectors feature an expanded beam optical interface that minimizes the risk of signal loss from dust or misalignment, along with a hermaphroditic mechanical design allowing any two identical units to mate without gendered ends. They also support 4 or 12 optical fibers per connector and are built to meet military-grade durability standards. For employment, they are best used in deployable fiber networks, ruggedized avionics interfaces, and high-vibration systems
• ARINC 801 Fiber Optic Contacts: These contacts are designed for high-density integration in modern aircraft systems, accommodating both single- and multi-mode fibers for high-speed data transmission. Compatible with ARINC 600 and MIL-DTL-38999 connector platforms, they employ a standardized 1.25 mm ceramic ferrule. For employment, they are best used in avionics networks, cockpit displays, and high-speed backbone systems

Shared Features

• Immunity to electromagnetic interference
• High-speed data support over long distances without signal degradation

5. Hermetically Sealed Bulkhead Connectors

For aircraft systems where electrical continuity must be preserved across sealed or pressurized boundaries, Amphenol’s hermetic connectors are prized for maintaining environmental isolation with uninterrupted transmission. These connectors are specifically designed to prevent gas or fluid leakage, making them a trusted choice for applications exposed to pressure differentials, fuel vapors, and other environmental contaminants.

Features

• Glass-to-metal sealing prevents leakage and ensures long-term hermeticity
• Available in familiar configurations, including MIL-DTL-26482 and 38999 styles
• Can accommodate power, signal, or mixed-contact layouts

Best Uses

• Fuel tank monitoring systems
• Hydraulic system control sensors
• Environmental data sensors exposed to sealed zones
