Product Safety Information
3. HANDLING
THIS NOTE MUST BE READ IN CON-
JUNCTION WITH THE PRODUCT DATA
(iii) Other important information
Care must be taken to avoid damage
to any component parts of electrical connec-
tors during installation and use. Although
there are normally no sharp edges, care
must be taken when handling certain com-
ponents to avoid injury to fingers. Electrical
connectors may be damaged in transit to the
customers, and damage may result in cre-
ation of hazards. Products should therefore
be examined prior to installation/use and
rejected if found to be damaged.
Cannon continuously endeavors to improve
their products. Therefore, Cannon products
may deviate from the description, technical
data and shape as shown in this catalog and
data sheets.

1. MATERIAL CONTENT AND PHYSICAL
FORM
Electrical connectors do not usually contain
hazardous materials. They contain conduct-
ing and non-conducting materials and can
be divided into two groups.
4. DISPOSAL
Product Warranty
Incineration of certain materials may release
noxious or even toxic fumes.
ITT Cannon, a Division of ITT Industries,
Inc. manufactures the highest quality prod-
ucts 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 devi-
ates from the stated operating specifications
is not recommended and may be unsafe. No
information and data contained in this publi-
cation shall be construed to create any liabil-
ity on the part of Cannon. Any new issue of
this publication shall automatically invalidate
and supersede any and all previous issues.
A limited warranty applies to Cannon prod-
ucts. Except for obligations assumed by
Cannon under this warranty, Cannon shall
not be liable for any loss, damage, cost of
repairs, incidental or consequential dam-
ages of any kind, whether or not based on
express or implied warranty, contract, negli-
gence 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 publi-
cation is not to be construed as an offer. It is
intended merely as an invitation to make an
offer. By this publication, 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 per-
mitted, indicating the source. However, Can-
non's prior consent must be obtained in all
cases.
a) Printed circuit types and low cost audio
types which employ all plastic insulators and
casings.
5. APPLICATION
Connectors with exposed contacts should
not be selected for use on the current supply
side of an electrical circuit, because an elec-
tric 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 can-
not be transmitted in any way to exposed
metal parts of the connector body. The con-
nector 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 conducting particles. Circuit
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.
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.
2. FIRE CHARACTERISTICS AND ELEC-
TRIC SHOCK HAZARD
There is no fire hazard when the connec-
tor 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 compo-
nent parts may cause electric shock or
burns. Live circuits must not be broken
by separating mated connectors as this
may cause arcing, ionization and burn-
ing. 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 applica-
tion 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 car-
bonization of insulation and tracking paths.
Fire can then result in the presence of com-
bustible materials and this may release nox-
ious fumes. Overheating may not be visually
apparent. Burns may result from touching
overheated components.
IMPORTANT GENERAL INFORMATION
(i) Air and creepage paths/Operating volt-
age. 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.
