Amphenol Air LB Germany GCA/GCB/VG95234 Circular MIL Spec Connectors

Amphenol Air LB Germany GCA/GCB/VG95234 Circular MIL Spec Connectors feature reverse bayonet or threaded coupling, a nickel surface, and solder contacts. The reverse bayonet coupling and an ondular washer guarantee fast and effortless locking/unlocking and avoid an unintentional unlatch due to heavy vibrations. The connectors offer high liability and use the same installation dimensions and contact arrangements as MIL-C-5015 connectors. These components are also coevally waterproof and resistant to vibrations and wear. Common applications include industrial plants and railway vehicles as well as propulsion technologies, machine tools, measurement, and robotics.

The GCA connectors are offered with two different locking systems with the same variety of options. The GCA components feature a threaded coupling with intermateable and interchangeable with other connectors according to MIL-DTL-5015 and SAS-SA50151. The GCA-B and GCB-B components offer a reverse bayonet coupling, conform to VG95234, and are in accordance with MIL-C-5015. The VG95234 connectors are equipped with an individual wire sealing grommet.
