CHM 2.0
Connector System acc to IEC 61076-4-101
The long contacts with 11,25 mm are predominantly used for the shielding
rows z and f.
Definition of Terms
Connector according to IEC 61076-4-101
The hardmetric connector system CHM 2.0 was developed according to
the international standard IEC 61076-4-101. As a result, a worldwide
standard for the combination of PCBs is safeguarded by multicontact
plug-and-socket connectors for customers.
Through-hole specification of the PCB
Through-plated holes for signal contacts and shieldings in press-fit
techniques.
PCBs can be exchanged without problems from system to system.
Important parameters like fixing, shielding and coding remain compatible
to all applications.

The spacing
The CHM 2.0 connectors have been developed with a spacing of 2 mm
between contacts. These connectors are modular and therefore can be
stacked together without interrupting the continuity of the 2 mm design.
No space is wasted within a row of connectors.

Module stacking
To improve stacking and to avoid accidental reversal of connectors the
end of the housings engage the adjacent connector to insure exact
positioning onto the PCB board and give the modules the necessary
support.
Coding
In order to avoid accidental plug-in among PC boards the IEC 61076-4-
101 standard provides protection through coding. Coding keys are easily
hand inserted into the multifunction block of the connector module A, L
and M. The pins are colour coded for fast visual recognition.
Multifunction block
The modules A, L, M and compact PCI are equipped with a multifunction
block. The coding devices, according to the IEC standard, can be added
to the multifunction block. The guides guaranty the correct mating and
prohibit accidental reversal of the male and female connectors.
The coding devices may be assembled by a single plug and pulling tool
and/or again removed.
Contact length of the rear and front mating area
ITT Industries Cannon offers 3 different lengths for the front mating area
and 4 lengths for the rear mating area for the CHM 2.0 male connectors.
A tin-plated Wire Wrap type is equally available. Different contact lengths
are required for signal and ground contacts to establish first mate and
last break features.

CHM 2.0 modules offer a great versatility to optimize large contact densities.
Especially the combination with coaxial or fiberoptic connections.
Stacking can be arranged from 50 mm using type A module, increasing
in 25 mm steps to required lengths.
Connectors with multifunction block (type A, M, L) are preferably used
at the top of any column. Type B is only used between other modules.
The modules type C and N (25 mm) are polarized and are used at the
bottom end of the columns.
Correct mating is assured by use of coding keys within the multifunction
block and by use of type C and N modules.

Product Safety Information
THIS NOTE SHOULD BE READ IN CONJUNCTION
WITH THE PRODUCT DATA SHEET/CATALOGUE.
FAILURE TO OBSERVE THE ADVICE IN THIS INFOR-
MATION SHEET AND THE OPERATING CONDITIONS
SPECIFIED IN THE PRODUCT DATA SHEET/
CATALOGUE COULD RESULT IN HAZARDOUS
SITUATIONS.
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.
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.
4. DISPOSAL
Incineration of certain materials may release
noxious or even toxic fumes.
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 harness-
ing.
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.
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, conducting 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.
2. Temperature
All information given are temperature limits. The
operation temperature depends on the individual
application.
a) Printed circuit types and low cost audio types
which employ all plastic insulators and casings.
3. Other important information
Cannon continuously endeavours to improve their
products. Therefore, Cannon products may deviate
from the description, technical data and shape as
shown in this catalogue and data sheets.
b) Rugged, Fire Barrier and High Reliability types
with metal casings and either natural rubber,
synthetic rubber, plastic or glass insulating
materials.
4. Harnessing and Assembly Instructions
If applicable, our special harnessing and/or assem-
bly instruction has to be adhered to. This is provid-
ed at request.
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 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 terminals. Overheating may
occur if the ratings in the Product Data Sheet/
Catalogue are exceeded and can cause breakdown
of insulation and hence electric shock.
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.
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 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.
