HAZARDOUS SITUATIONS.
1 MATERIAL CONTENT AND PHYSICAL FORM
2 FIRE CHARACTERISTICS AND ELECTRIC
Electrical connectors do not usually contain
hazardous materials. They contain conducting
and non-conducting materials and can be
divided into two groups.
a) Printed circuit types and low cost audio types
which employ all plastic insulators and casings.
b) Rugged, Fire Barrier and High Reliability types
with metal casings and either natural rubber,
synthetic rubber, plastic or glass insulating
materials. Contact materials vary with type of
connector and also application and are usually
manufactured from either: Copper, copper
alloys, nickel, alumel, chromel or steel. In
special applications, other alloys may be
specified.
SHOCK HAZARD
There is no fire hazard when the connector is
correctly wired and used within the specified
parameters. Incorrect wiring or assembly of
the connector or careless use of metal tools or
conductive fluids, or transit damage to any of
the component parts may cause electric
shock or burns. Live circuits must not be
broken by separating mated connectors as
this may cause arcing, ionisation and burning.
Heat dissipation is greater at maximum
resistance in a circuit. Hot spots may occur
when resistance is raised locally by damage,
e.g. cracked or deformed contacts, broken
strands of wire. Local overheating may also
result from the use of the incorrect application
tools or from poor quality soldering or slack
screw terminals. Overheating may occur if the
ratings in the product Data Sheet/Catalog are
exceeded and can cause breakdown of
insulation and hence electric shock.
If heating is allowed to continue it intensifies by
further increasing the local resistance through
loss of temper of spring contacts, formation of
oxide film on contacts and wires and leakage
currents through carbonisation of insulation and
tracking paths. Fire can then result in the
presence of combustible materials and this may
release noxious fumes. Overheating may not be
visually apparent. Burns may result from
touching overheated components.

5 APPLICATION
ITT Cannon manufactures the highest quality products available in the marketplace; however these products are intended to be
used in accordance with the specifications in this publication. Any use or application that deviates from the stated operating
specifications is not recommended and may be unsafe. No information and data contained in this publication shall be construed to
create any liability on the part of ITT Cannon. Any new issue of this publication shall automatically invalidate and supersede any and
all previous issues. A limited warranty applies to ITT Cannon products. Except for obligations assumed by ITT Cannon under
this warranty, ITT Cannon shall not be liable for any loss, damage, cost of repairs, incidental or consequential damages of any
kind, whether or not based on express or implied warranty, contract, negligence or strict liability arising in connection with
the design, manufacture, sale, use or repair of the products. Product availability, prices and delivery dates are exclusively
subject to our respective order confirmation form; the same applies to orders based on development samples delivered. This
publication is not to be construed as an offer. It is intended merely as an invitation to make an offer. By this publication, ITT Cannon
does not assume responsibility or any liability for any patent infringements or other rights of third parties which may result from its
use. Reprinting this publication is generally permitted, indicating the source. However, ITT Cannon’s prior consent must be
obtained in all cases.
Care must be taken to avoid damage to any
component parts of electrical connectors
during installation and use. Although there are
normally no sharp edges, care must be taken
when handling certain components to avoid
injury to fingers.
Electrical connectors may be damaged in transit
to the customers, and damage may result in
creation of hazards. Products should therefore
be examined prior to installation/use and
rejected if found to be damaged.
Incineration of certain materials may release
noxious or even toxic fumes.
Connectors with exposed contacts should not
be selected for use on the current supply side of
an electrical circuit, because an electric shock
could result from touching exposed contacts on
an unmated connector. Voltages in excess of 30
V ac or 42.5 V dc are potentially hazardous and
care should be taken to ensure that such
voltages cannot be transmitted in any way to
exposed metal parts of the connector body. The
connector and wiring should be checked, before
making live, to have no damage to metal parts or
insulators, no solder blobs, loose strands,
conducting lubricants, swarf, or any other
undesired
resistance and continuity check should be
made to make certain that there are no high
resistance joints or spurious conducting paths.
Always use the correct application tools as
specified in the Data Sheet/Catalog.
Do not permit untrained personnel to wire,
assemble or tamper with connectors. For
operation voltage please see appropriate
national regulations.

IMPORTANT GENERAL INFORMATION
(i) Air and creepage paths/Operating voltage
The admissible operating voltages depend on the
individual applications and the valid national and
other applicable safety regulations.
For this reason the air and creepage path data are
only reference values. Observe reduction of air and
creepage paths due to PC board and/or
harnessing.
(ii) Temperature
All information given are temperature limits. The
operation temperature depends on the individual
application.
(iii) Other important information
ITT Cannon continuously endeavours to improve
their products. Therefore, ITT Cannon products
may deviate from the description, technical data
and shape as shown in this catalog and data
sheets.
