IMPROVED COUPLING OVER THREADED COMMERCIAL SAE-AS50151 (MIL-DTL-5015)
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. For our full product descriptions of the Amphenol AIB/GT series, please see the specifications below.
Features
- Commercial and Military
AIB/GT series connectors are made in accordance with German military specification VG95234 and MIL-DTL-5015. Originally designed for NATO combat vehicles, aircraft, and airborne equipment, these rugged connectors are now in a broad range of demanding commercial applications from trucks to industrial robots. - Simple and Fast Mating and Un-Mating
AIB/GT series connectors use a unique “reverse bayonet” coupling system that allows for mating and un-mating with a simple 120˚ rotation without compromising shock, vibration, or moisture resistance. The large, open ramps are easily cleaned of mud or other contaminants. The ramp coupling system eliminates the possibility of cross-threading and thread damage possible with standard MIL-DTL-5015 threaded connectors. This design is easier to mate in cold weather, tight spaces, or on equipment which must be disassembled frequently. - Shock and Vibration Resistant
AIB/GT series connectors are supplied with military-standard resistant sealing and a three-point bayonet coupling nut. The three-point bayonet coupling incorporates a wave spring and washer specified by the rail industry. AIB/GT series connectors pass the most stringent tests of shock and vibration performance while maintaining proper continuity and water tightness. Rugged aluminum alloy shell and hardware are light in weight yet highly resistant to damage. - Audible, Visual and Tactile Confirmation of Mating
AIB/GT series connectors provide three independent checks that the connector halves are mated. When the coupling nut is fully rotated, the three studs snap into the end of the ramps with a loud “click” (audible). The user can feel the bolts click into the grooves (tactile). Blue dots on the receptacle and coupling nut are aligned when the connector is properly mated (visual). - Environmental
The sealing is not compromised by any of the operating conditions defined in MIL-DTL-5015 and is completely watertight when mated. - Broad Temperature Range
These connectors will operate in temperatures from -67˚ to +257˚F (-55˚ to +125˚C). High-temperature and zero-halogen insulators are also available. Contact us for ordering information. - Wide Range of Wire Gauges and Current-Carrying Capability
Up to 150/245 amps with accommodations for wire gauges from size 26 to size 0 AWG. - Wide Variety of Contacts
High-reliability screw machine contacts with silver or gold plating are available in sizes from 20 to 0 to accommodate wire gauges from 26 to 0 AWG. Solder, crimp, PC, and thermocouple contacts are available. - Intermateable and Intermountable With All VG95234 Connectors
The standard MIL-DTL-5015 layouts and dimensions ensure intermateability and intermountability with all connectors made in accordance with VG95234.
AIB/GT connectors use rail industry-standard crimp contacts that are completely interchangeable with other rail connectors such as Litton/Veam CIR series.
