ULTRA RELIABLE REVERSE BAYONET CONNECTORS

ITT Cannon’s CA-Bayonet connectors (CA-B / CB) were derived from MIL-DTL-5015 standards but use an improved, 3-point reverse-bayonet locking system that is VG95234 approved. With the enhanced coupling system, CA-B / CB connectors offer exceptional shock and vibration resistance for military systems/ground vehicles, heavy equipment, industrial equipment and rail applications.

In addition to over 140 arrangements, 12 connector sizes available for 1 to 65 circuits and diverse accessory options, the CA Bayonet series offers a wide range of plating. From VG approved Cadmium and black ZnCo to ITT’s RoHS & REACH compliant ZnNi Blue Generation plating which offers 500 hours salt spray resistant, this makes ITT Cannon’s CA Bayonet series one of the most versatile, high-reliability connector series on the market.

For full product details on the CA-B / CB bayonet series, see the specifications below.

 

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
  Fully tested to VG 95234 standards.
• 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 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 VG 95234 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 VG 95234 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)
