Product Safety Information
This note must be read in conjunction with the product data sheet/catalog. failure to observe
the advice in this information sheet and the operating conditions specified in the product data
sheet/ catalog could result in hazardous situations.
1. MATERIAL CONTENT AND PHYSICAL FORM
5. APPLICATION
(a) Electrical connectors do not usually contain hazardous materials.
They contain conducting and non-conducting materials and can be
divided into two groups:
Printed circuit types and low cost audio types which employ all plastic
insulators and casings.
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 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 ELECTRIC
SHOCK HAZARD
There is no fire hazard when the connector is correctly wired and
used within the specified parameters.
IMPORTANT GENERAL INFORMATION
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, ionization 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 over- heating 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 carbonization 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.
(i) Air and creepage paths/operating voltage. The admissible operating
voltages depend on the individual applications and the valid national
and other applicable safe- ty 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. 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.
ITT Cannon is a business unit of ITT Cannon Inc., which 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 Cannon. Any new
issue of this publication shall automatically invalidate and supersede
any and all previous issues
3. HANDLING
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.
All data subject to change without notice.
4. DISPOSAL
Incineration of certain materials may release noxious or even
toxic fumes.
