Product Safety Information
THIS NOTE SHOULD BE READ IN CONJUNCTION WITH
THE PRODUCT DATA SHEET/CATALOGUE. FAILURE TO
OBSERVE THE ADVICE IN THIS INFORMATION SHEET
AND THE OPERATING CONDITIONS SPECIFIED IN THE
PRODUCT DATA SHEET/CATALOGUE COULD RESULT
IN HAZARDOUS SITUATIONS.
1. MATERIAL CONTENT AND PHYSICAL
FORM
Electrical connectors do not usually contain hazardous
materials. They contain conducting and non-conduct-
ing materials and can be divided into two groups.
a) Printed circuit types and low cost audio types which
employ all plastic insulators and casings.
3. HANDLING
Care must be taken to avoid damage to any com-
ponent parts of electrical connectors during instal-
lation 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.
4. DISPOSAL
Incineration of certain materials may release noxious
or even toxic fumes.
Always use the correct application tools as specified in
the Data Sheet/Catalogue.
Do not permit untrained personnel to wire, assemble or
tramper with connectors.
For operation voltage please see appropriate national
regulations.
IMPORTANT GENERAL INFORMATION.
1. Air and creepage paths/Operating voltage
The admissible operating voltages depend on the
individual applications and the valid national and
other applicable safety 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. Incorrect wiring or assembly of the
connector or careless use of metal tools or con-
ductive fluids, or transit damage to any of the
component parts may cause electric shock or
burns. Live circuits must not be broken by sepa-
rating 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 ter-
minals. Overheating may occur if the ratings in the
Product Data Sheet/Catalogue 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 mate-
rials and this may release noxious fumes. Overheating
may not be visually apparent. Burns may result from
touching overheated components.
5. APPLICATION
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 can not 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, con-
ducting lubricants, swarf, or any other undesired
conducting particles. Insulation resistance should be
checked to make certain that no low resistance joints
or spurious conducting path are existing between
contacts and exposed metal parts of the connector
body. Further the contact resistance of the connectors
should be measured within the electrical circuit in
order to identify high resistances which result in
excessive connector heating.
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.
2. Temperature
All information given are temperature limits. The
operation temperature depends on the individual
application.
