mating cycles.

Corona - A discharge of electricity caused by the

ionisation of the air around a conductor just prior to total

breakdown or flashover.

Crimp - The action of distorting a metal tube to give

intimate contact with a conductor; a good crimp should

be gas tight and not be impacted by environmental

change.

Crimp Dies - The tool inserts which determine the shape

of the distortion to create a consistently good crimp.

Crimp Tool - The tool which holds crimp dies to apply the

necessary force.

Cross T

transferred from one signal carrying line to an adjacent

line.

exceeds a predetermined level.

PRODUCT WARRANTY

Dimensions shown in mm (inch)

Specifications and dimensions subject to change

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

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

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.
