Cannon VG/CA-Bayonet
Introduction
Connector Design
Due to the rugged shell made of an aluminium alloy, these
connectors withstand most severe conditions. Olive drab
chromate coating over cadmium plating protects the surface of
the shell.
Cannon offers two plating solutions to customers refusing
cadmium plating. Zinc cobalt green offers similar properties like
cadmium plating while zinc cobalt black is RoHS compliant.
Over 180 contact arrangements are available for 1 to 65 circuits
and up to 245 A per unit.
The insulators are made of high quality polychloroprene and
withstand temperatures from -67°/+257°F (-55/125°C). This
material is self-extinguishing, resistant against hydraulic fluids,
jet fuel, diesel fuel, gasolines, lubricants, brake and fire
extinguisher fluids (short wetting only). In case of lifetime
moistening ITT Cannon offers FKM insulators as an alternative.
The contacts are made of copper alloy plated with a hard silver
finish guarantee at least 500 mating cycles. There are solder,
crimp and PCB contacts in place. The crimp contacts offer a
comprehensive range of termination reductions. All solder
contacts feature a special passivation to comply with ROHS
requirements. The crimp contacts allow highly reliable crimping
with wires when using the recommended tools according to
VG95234. Crimp contacts can be exchanged at least five times
still preserving specified contact retention.
The coupling unit is featured by the Cannon roller bolts made
of stainless steel actually rolling down the mating ramps, thus
reducing coupling force by the operator. In addition, the
Cannon design employs two coupling nut versions for different
application cases, with and without wavespring and washer.
The version without wavespring guarantees perfect sealing
while the other version stands up to high vibration levels.
The bayonet design allows fast and easy coupling and
uncoupling. An audible control by metallic sound and
visual control by colour-marked snap-in position offer
additional coupling security.
VG connectors are basically designed for single wire harnessing.
For full environmental sealing each conductor is sealed com-
pletely within the grommet. However, Cannon offers as an
alternative O-ring sealed PG and
metric gland adaptors for faster
harnessing standing up to the same
sealing level than the VG types.
A
Cannon CA-Bayonet series was designed in accordance with
the VG95234 specification. This versatile and highly reliable
connector series is an improvement on the well established
MIL-C-5015 series. CA-Bayonet has a proven “reverse bayonet”
coupling design that offers exceptional vibration protection, by a
simple 120° turn.
Initially designed for aircraft and airborne applications, these
rugged connectors are used in the electrical equipment of vari-
ous off-road vehicles, construction machinery, industrial devices,
railroad and military wheelers.
Connectors in accordance with VG95234 are interchangeable
with the corresponding MIL-C-5015 connectors. Both connector
lines feature the same shell dimensions and contacts layouts.
However, due to the different coupling systems (MIL-C-5015
threaded coupling, VG95234 bayonet coupling) they are not
intermateable.

Advantages
– rugged shell design
– environmental
– bayonet coupling for easy mating and unmating
– vibration proof
– waterproof up to 1 bar (35 feet of water)
Cannon has the complete VG95234 program available and, in ad-
dition, many other types which exceed the requirements of
VG95234 and MIL-C-5015.
Attention:
Metal shell connectors which may be touched are not
suitable for mains power.

Operating voltage and connector usage
Connectors in equipments must not be separated or mated
under load when used per specifications.
As according to specification the connectors are suitable for an
operating voltage of 50 V (see Product Safety Information).
However, this is only valid, when the connectors are freely
accessible during operation and consequently might be
touchable. When the connectors will be operated with line
voltage, please contact ITT Customer Service for an alternative
connector solution.

Besides the normal position further insulator
positions are possible for Cannon connectors
(see CA-Bayonet Catalog) to prevent mismat-

the socket insulator, however, in opposite
clockwise direction. This information refers to
the mating side of the contact insulator.
