F O R M
Electrical connectors do not usually contain
hazardous materials. They contain conduct-
ing 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,

Incineration of certain materials may release
noxious or even toxic fumes.
5 . A P P L I C A T I O N
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 cannot be
transmitted in any way to exposed metal
parts of the connector body. The connector
and wiring should be checked, before mak-
ing live, to have no damage to metal parts or

Reprinting this publication is generally per-
c a u s e a r c i n g , i o n i z a t i o n a n d b u r n i n g . Heat
dissipation is greater at maximum resistance
in a circuit. Hot spots may occur when resist-
ance 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

lation 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 compo-
nents.

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.
