Product Safety Information

Cannon ZIF Connectors

1. MATERIAL CONTENT AND PHYSICAL

FORM

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.

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 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

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 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.

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.

4. DISPOSAL

Incineration of certain materials may release

noxious or even toxic fumes.

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 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.

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

their products. Therefore, Cannon products

may deviate from the description, technical

data and shape as shown in this catalog and

data sheets.
