The Amphenol AIB/GT series replaces the threaded coupling used in commercial SAE-AS50151 (MIL-DTL-5015) connectors with a positive, quick-mating, three-point reverse bayonet lock for improved performance. These Amphenol AIB/GT Series connectors are an ideal cost-effective option for applications requiring reliability in harsh environments, and are the world-standard for rail, mass transit, and military ground vehicle applications. The Amphenol AIB/GT series has the same shell dimensions, contact layouts, contacts, and performance characteristics as the SAE-AS50151 (MIL-DTL-5015) threaded connectors; however, the two series do not intermate. These connectors are sealed to withstand moisture, condensation, vibration and flash-over. Over 180 contact layouts are available, in variations that allow for just power, just signal, or a mix of both contact types. There is also an additional option of high-power RADSOK contacts.
