Marine Circular Connectors

Amphenol Military & Aerospace’s Marine Circular Connectors, manufactured by Amphenol Air LB Germany, are designed for platforms exposed to saltwater, humidity, and mechanical abrasion. These connectors employ the VG‑approved Version B marine bronze alloy, providing durable resistance to corrosion without using cadmium or chromium(VI) plating systems.

Environmental and Material Performance

The marine bronze shell delivers long‑term stability in maritime and coastal environments while maintaining full electrical shielding continuity. Each connector passes a five‑day cyclic salt‑spray test per VG95319‑2 (Test 5.50) and DIN EN 60068‑2‑52 (Test Kb), exceeding the stress levels of typical MIL standards. The design is RoHS and REACH‑compliant, ensuring environmentally responsible production and finish selection.

Mechanical and Application Considerations

• Shell material: VG‑approved Marine Bronze with self‑protective corrosion resistance
• Finishes: Cadmium‑ and chromium(VI)‑free
• Coupling: Standard threaded or bayonet circular interfaces typical of VG series connectors
• Operational resistance: Mechanical endurance under vibration and sand abrasion for shipboard and coastal installations

Typical Uses

Marine circular connectors are utilized in shipboard communications, navigation electronics, maritime aerospace systems, and coastal defense equipment. The VG approval assures electrical integrity and structural reliability where extended salt‑fog protection is required.

Compatibility and Options

The connectors are available across multiple Amphenol Air LB series with equivalent contact arrangements to standard VG families, simplifying cross‑installation with existing defense and industrial infrastructures. Engineers can select housing configurations and backshell variants according to mechanical and sealing requirements.
