Amphenol Military & Aerospace High-Speed MIL-Spec Circular Connectors integrate the durability of traditional military-qualified shells with contact technology optimized for modern digital architectures. These interconnects enable data and signal integrity in rugged environments across airborne, ground, and naval systems where high-speed communication lines must survive vibration, temperature extremes, and EMI exposure.

Mechanical and Environmental Integrity

Constructed in MIL-DTL-38999 and MIL-DTL-26482 type housings, these connectors are available in aluminum, stainless steel, and composite shells with plating and sealing options tailored for harsh environment operation. Threaded or bayonet coupling options offer secure mating under dynamic mechanical load.

High-Speed Contact Interfaces

• Compatible with coax, twinax, and quadrax contact systems for high-speed differential links such as Ethernet, Fibre Channel, and ARINC- or VME-based data buses.
• Supports transmission paths requiring impedance control and EMI containment for reliable signal performance in compact multi-channel configurations.

Integration and Interoperability

• Backshell, strain-relief, and EMI termination hardware compatible with standard Amphenol and legacy MIL-Spec accessories.
• Multiple shell sizes and insert arrangements to match bandwidth, pin count, and grounding requirements.
• Designed for straightforward qualification substitution within existing MIL-DTL-38999 architectures.

Applications

• High-speed avionics modules and mission computers.
• Embedded network expansion in ground or maritime systems.
• Sensor, data bus, and payload interfaces requiring EMI-shielded, low-loss connectivity.

Amphenol’s extensive MIL-Spec heritage ensures that each configuration maintains electrical stability and mechanical retention in extreme settings. Engineers can specify shell materials, coupling type, contact geometry, and accessory interfaces to align these high-speed connectors with the system-level design and qualification criteria of demanding defense and aerospace applications.
