ITT Cannon CA-B / CB Series Bayonet Connectors



5015 PERFORMANCE WITH IMPROVED BAYONET COUPLING

ITT Cannon CA-B / CB series bayonet connectors are similar to standard MIL-DTL-5015 (MIL-5015), but use an improved coupling system - a quick-mating 3-point reverse-bayonet lock. ITT Cannon CA-B / CB series bayonet connectors have the same shell dimensions, contact layouts and performance characters as a standard 5015, but they are not intermateable. CA-B / CB bayonet connectors are harsh environment connectors excellent for military ground systems and vehicles. ITT Cannon CA-B / CB connectors are mil-spec, qualified to MIL-DTL-5015 & VG 95234 NATO specifications. Hundreds of contact layouts are available. Common variations include 2-pin connectors, 3-pin connectors, 4-pin connectors, 12-pin connectors and 16-pin connectors. The CA-B / CB is a waterproof connector that is completely sealed and resistant to condensation, vibration, and flash-over. For full product details on the CA-B / CB bayonet series, see the specifications below.

FEATURES

ITT CANNON CB SERIES MIL-DTL-5015 CONNECTORS FEATURES

  • Full Military Temperature Range
    CB connectors will operate in temperatures from -55° to +125°C (-67° to +257°F) under the harshest possible conditions.

  • Wide Range of Wire Gauges and Current-Carrying Capability
    Up to 245 amps with wire gauges from size 20 up to size 0 AWG.

  • Resilient Insulator & Grommet
    A resilient polychloroprene insulator and rear sealing grommet guarantees a liquid-tight assembly. Crimp contacts can be inserted and removed a minimum of five cycles for field service.

  • Wide Variety of Contacts
    High-reliability screw machine contacts with silver or gold plating are available in sizes from 20 through 0 to accommodate wire gauges from 24 to 0 AWG. Solder, crimp, PC, and thermocouple contacts are available.

  • Rugged Shell
    Aluminum alloy shell and hardware create a rugged connector with minimal weight. These connectors have been used extensively in the military for many years and have proven their reliability in a wide range of combat and industrial applications.

  • Environmental
    Vibration and water-proof. Will perform in the full range of MIL-DTL-5015 or VG 95234 environments.

  • Simple Mating and Un-mating
    CB bayonet style connectors use a unique “reverse bayonet” coupling system for ease of use. This system allows mating and un-mating of the connector halves with a simple 120° rotation - without compromising shock, vibration or moisture resistance. The coupling nut employs the exclusive Cannon “roller bolt” which is actually three small stainless steel wheels that roll down the mating ramps. The large, open ramps can be easily cleaned. The roller bolt and ramp coupling system eliminates the possibility of cross threading and thread damage possible with standard MIL-DTL-5015 threaded connectors. This quick mating design is easier to mate in cold weather, tight spaces, or on equipment which must be disassembled frequently.

  • Proven Reliability
    CA–Bayonet has been used extensively in military vehicles such as the M1 Tank, the Hummer, advanced locomotives, transit cars and auxiliary equipment.

  • Audible, Visual & Tactile Confirmation of Mating
    CB connectors provide the user with 3 independent checks that the connector halves are mated. When the coupling nut is fully rotated, the three roller bolts snap into the end of the ramps with a loud “click” (audible confirmation). At that same moment, the user can actually feel the bolts click into the grooves (tactile confirmation). A red arrow on the receptacle and a red dot on the coupling nut are aligned when the connector is properly mated (visual confirmation).

  • Environmental Sealing
    The sealing of this connector is not compromised by any of the operating conditions defined in MIL-DTL- 5015 or VG95234. Mated connectors are completely watertight when tested to 1 bar (35 feet) per the requirements of the VG 95234 specification. Unlike CT connectors, the receptacle contacts are not bonded into the inserts unless requested by the end user.

  • Intermateable and Intermountable with all VG 95234 Connectors
    The standard MIL-DTL-5015 layouts and dimensions ensure intermateability and intermountability with all connectors made in accordance with VG 95234. When front mounted, all CB connectors are intermountable with standard threaded MIL-DTL-5015 connectors, making it possible to upgrade without the need to change panel cutouts or clearances in most cases.

  • Agency Approvals
    Numerous European & International Rail Approvals. (Contact us for current listing)
