RUGGED REVERSE BAYONET CONNECTORS FOR POWER AND SIGNAL APPLICATIONS
Amphenol ACA-B connectors are designed for commercial and industrial applications requiring a bayonet style coupling device for high power and/or signal. Similar in design to a SAE-AS50151, ACA-B’s are a quick, positive mating type of connector, perfect for markets such as factory automation, robotics, and process control equipment. Amphenol’s ACA-B series has proven itself valuable in the military ground vehicle and alternative energy markets because of its low cost, high reliability design. For full product details on the ACA-B bayonet series, see the specifications below.
Features
- Commercial and Military
ACA-B series connectors are made in accordance with German military specification VG95234 and SAE-AS50151 (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
ACA-B 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 SAE-AS50151 (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
ACA-B 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. ACA-B 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
ACA-B 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 SAE-AS50151 (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 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, co-ax, and thermocouple contacts are available. - Intermateable and Intermountable With All VG95234 Connectors
The standard SAE-AS50151 (MIL-DTL-5015) layouts and dimensions ensure intermateability and intermountability with all connectors made in accordance with VG95234.
All ACA-B connectors are intermountable with standard threaded SAE-AS50151 (MIL-DTL-5015) connectors, often making it possible to upgrade without changing panel cutouts or clearances.
