A perfect crimp connection is gastight, therefore corrosion
free and amounts to a cold weld of the parts being connected.
For this reason, major features in achieving high quality crimp
connections are the design of the contact crimping parts and of
course the crimping tool itself. Wires to be connected must be
carefully matched with the correct size of crimp contacts. If these
basic requirements are met, users will be assured of highly relia-
ble connections with low contact resistance and high resistance
to corrosive attack.
The economic and technical advantages are:
● Constant contact resistance as a result of precisely repeated
crimp connection quality
● Corrosion free connections as a result of cold weld action
● Pre-preparation of cable forms with crimp contacts tted
● Optimum cost cable connection
Requirements for crimp connectors are laid down in DIN IEC
60 352-2, Amend.2, as illustrated in the table.
Pull out force of stranded wire
The main criterion by which to judge the quality of a crimp con-
nection is the retention force achieved by the wire conductor in
the terminal section of the contact. DIN IEC 60 352,
part 2, denes the extraction force in relation to the cross-section
of the conductor. When tted using HARTING crimping tools
and subject to their utilization in an approved manner, our crimp
connectors comply with the required extraction forces.
Crimping tools
Crimping tools (hand operated or automatic) are carefully desi-
gned to produce with high pressure forming parts a symmetrical
connection of the crimping part of the contact and the wire being
connected with the minimum increase in size at the connection
point.The positioner automatically locates the crimp and wire at
the correct point in the tool.
A ratchet in the tool performs 2 functions:
● It prevents insertion of the crimp into the tool for crimping
before the jaws are fully open
● It prevents the tool being opened before the crimping action is
completed
Identical, perfectly formed, connections can be produced using
this crimping system.

Terminations
Axial screw terminal
This termination combines the benets of screw and crimp termi-
nations:
● Less space required
● Easy handling
● No special tools
Remarks on the axial screw technique
The wire gauges mentioned in the catalogue refer to geometric
wire gauges of cables.
Background:
According to DIN VDE 0295 for cables and insulated wires the
wire gauge will be determined by conductance (Ω/km) and maxi-
mum wire diameter. A minimum cable diameter is not specied!
(Example:nominal wire gauge 95 mm² → real, geometric wire
gauge 89 mm²)
Recommendation:
The use of cables with an extreme geometric wire gauge deviati-
on should be checked separately with the use of the axial screw
termination.
Strain relief:
For safe operation the cable must be xed at an adequate
distance from the terminal to ensure that the contact is protected
against radial stress.
Details for professional strain relief design can be found in the
standard DIN VDE 0100-520: 2003-06 (see enclosed table).

9 < D < 15 300 400
15 < D < 20 350 450
20 < D < 40 400 550
Cables:
The axial screw technology is developed for wires according to
VDE 0295 class 5 (see table: Wire assembly according to VDE
0295). Deviating cable assemblies have to be tested separately.
Assembly remarks:
Before starting the assembly the user must ensure that the axial
cone is screwed fully downward to completely open the contact
chamber.
After stripping the cable insulation the strands must not be
twisted and the maximum cable insulation must not exceed the
recommended dimension.
Insert the wire completely into the contact chamber until the
copper strands reach the bottom. Keep the cable in position
while applying the recommended tightening torque.
Maintenance of the axial screw termination:
After initial assembly it is only allowed to reapply the recommen-
ded tightening torque once in order to avoid damage to individual
cable strands.

Electrical engineering data
General
The choice of connectors entails more than just considering factors
such as functionality, the number of contacts, current and voltage
ratings. It is equally important to take account of where the con-
nectors are to be used and the prevailing ambient conditions. This
in turn means that, dependent on the conditions under which they
are to be installed and pursuant to the relevant standards, different
voltage and current ratings may apply for the same connectors.
The most important influencing factors and the corresponding
electrical characteristics of the associated connectors are illus-
trated here in greater detail.
Overvoltage category
The overvoltage category is dependent on the mains voltage and
the location at which the equipment is installed. It describes the
maximum overvoltage resistance of a device in the event of a pow-
er supply system fault, e. g. in the event of a lightening strike.
The overvoltage category affects the dimensioning of components
in that it determines the clearance air gap. Pursuant to the relevant
standards, there are 4 overvoltage categories.
Equipment for industrial use, such as fall HARTING heavy
duty Han connector, fall into Overvoltage Category III.
Extract from DIN VDE 0110-1 and IEC 60 664-1,
Para. 2.2.2.1.1
Rated impulse voltages (Table 5 of DIN EN 61 984)
Equipment of overvoltage category I is equipment for connec-
tion to circuits in which measures are taken to limit transient
overvoltages to an appropriately low level.
Note: Examples are protected electronic circuits.
Equipment of overvoltage category II is energy-consuming
equipment to be supplied from the fixed installation.
Note: Examples of such equipment are appliances, portable
tools and other household equipment with similar loads.
If such equipment is subjected to special requirements with regard
to reliabiliy and availability, overvoltage category III applies.
Equipment of overvoltage category III is equipment in fixed
installations and for cases where the reliability and the
availability of the equipment is subject to special require-
ments.
Note: Examples of such equipment are switches in the fixed
installation and equipment for industrial use with perma-
nent connection to the fixed installation.
Equipment of overvoltage category IV is for use at the origin of
the installation.
Note: Examples of such equipment are electricity meters and
primary overcurrent protection equipment.

Electrical engineering data
Pollution degree
The dimensioning of operating equipment is dependent on envi-
ronmental conditions. Any pollution or contamination may give rise
to conductivity that, in combination with moisture, may affect the
insulating properties of the surface on which it is deposited. The
pollution degree influences the design of components in terms of
the creepage distance.
The pollution degree is defined for exposed, unprotected insula-
tion on the basis of environmental conditions.
HARTING heavy duty Han connectors are designed as stand-
ard for Pollution Degree 3.
Pollution degree 1
in air-conditioned or clean, dry rooms, such as computer and
measuring instrument rooms, for example.
Pollution degree 2
in residential, sales and other business premises, precision en-
gineering workshops, laboratories, testing bays, rooms used for
medical purposes. As a result of occasional moisture condensa-
tion, it is to be anticipated that pollution/contamination may be tem-
porarily conductive.
Pollution degree 3
in industrial, commercial and agricultural premises, unheated
storage premises, workshops or boiler rooms, also for the
electrical components of assembly or mounting equipment
and machine tools.
Pollution degree 4
in outdoor or exterior areas such as equipment mounted on the
roofs of locomotives or tramcars.
Extract from DIN VDE 0110-1 and IEC 60 664-1,
Para. 2.5.1
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Only non-conductive pollution occurs except
that occasionally a temporary conductivity caused by condensa-
tion is to be excepted.
Pollution degree 3: Conductive pollution occurs or dry non-
conductive pollution occurs which becomes conductive
due to condensation which is to be excepted.
Pollution degree 4: The pollution generates persistent conduc-
tivity caused by conductive dust or by rain or snow.
Special ruling for connectors
Subject to compliance with certain preconditions, the stand-
ard for connectors permits a lower pollution degree than that
which applies to the installation as a whole. This means that
in a pollution degree 3 environment, connectors may be used
which are electrically rated for pollution degree 2.
The basis for this is contained in DIN EN 61 984, Para.
6.19.2.2.
Extract form DIN EN 61 984, Para. 6.19.2.2
For a connector with a degree of protection IP 54 or higher
according to IEC 60 529 the insulating parts inside the enclo-
sure may be dimensioned for a lower pollution degree.
This also applies to mated connectors where enclosure is
ensured by the connector housing and which may only be dis-
engaged for test and maintenance purposes.
The conditions fulfills,
● a connector which is protected to at least IP 54 as per
IEC 60 529,
● a connector which is installed in a housing and which as
described in the standard is disconnected for testing and main-
tenance purposes only,
● a connector which is installed in a housing and which when
disconnected is protected by a cap or cover to at least IP 54,
● a connector located inside a switching cabinet to at least IP 54.
These conditions do not extend to connectors which when dis-
connected remain exposed to the industrial atmosphere for an
indefinite period.
It should be noted that pollution can affect a connector from the
inside of an installation outwards.
Typical applications in which to choose pollution
degree 2 connectors:
● A connector serving a drive motor which is disconnected only for
the purpose of replacing a defective motor, even when the plant
or system otherwise calls for pollution degree 3.
● Connectors serving a machine of modular design which are dis-
connected for transport purposes only and enable rapid erection
and reliable commissioning. In transit, protective covers or ad-
equate packing must be provided to ensure that the connectors
are not affected by pollution/contamination.
● Connectors located inside a switching cabinet to IP 54. In such
cases, it is even possible to dispense with the IP 54 housings of
the connectors themselves.

Other terms explained
Clearance air gap
The shortest distance through the air between two conductive ele-
ments (see DIN VDE 0110-1, Para. 1.3.3). The air gaps are deter-
mined by the surge voltage withstand level.
Creepage distance
Shortest distance on the surface of an insulating material between
two conductive elements (see DIN VDE 0110-1, Para. 1.3.3). The
creepage distances are dependent on the rated voltage, the pollu-
tion degree and the characteristics of the insulating material.
Working voltage
Fixed voltage value on which operating and performance data
are based. More than one value for rated voltage or rated voltage
range may be specified for the same connector.
Rated impulse voltage
The rated impulse voltage is determined on the basis of the over-
voltage category and the nominal power supply voltage. This level
in turn directly determines the test voltage for testing the overvolt-
age resistance of the connector (Waveform voltage in 1.2/50 µs
as per IEC 60 060-1).
Working current
Fixed current, preferably at an ambient temperature of 40 °C,
which the connector can carry on a permanent basis (without
interruption), passing simultaneously through all contacts which
are in turn connected to the largest possible conductors, with-
out exceeding the upper temperature limit.
The dependence of the rated current on ambient temperature is
illustrated in the respective derating diagrams.
Transient overvoltages
Short-term overvoltage lasting a few milliseconds or less, oscilla-
tory or non-oscillatory, generally heavily damped (see DIN VDE
0110-1, Para. 1.3.7.2). An overvoltage may occur as a result of
switching activities, a defect or lightening surge, or may be inten-
tionally created as a necessary function of the equipment or com-
ponent.
Power-frequency withstand voltage
A power-frequency overvoltage (50/60 Hz).
Applied for a duration of one minute when testing dielectric strength.
For test voltages in association with surge voltage withstand lev-
els, see extract from Table 8, DIN EN 61 984.

CTI (Comparative Tracking Index)
This figure gives an indication of the conductivity of insulating
materials and affects the specified creepage distances. The influ-
ence of the CTI value on the creepage distance is as follows: the
higher the index value, the shorter the creepage distance. The
CTI is used to divide plastics into insulation groups.
Breakdown of insulation groups:
I 600 ≤ CTI
II 400 ≤ CTI < 600
IIIa 175 ≤ CTI < 400
IIIb 100 ≤ CTI < 175
Protection levels as per IEC 60 529
The protection level describes the leak-proof character of hous-
ing, e. g. for electrical equipment. It ranges from IP 00 to IP 68.
HARTING heavy duty Han connectors feature a standard protec-
tion level of IP 65 (see page 00.09, Table based on DIN VDE 0470,
DIN EN 60 529, IEC 60 529).
Derating diagram as per DIN IEC 60 512
These diagrams are used to illustrate the maximum current carry-
ing capacity of components. The illustration follows a curve which
shows the current in relation to ambient temperature. Current car-
rying capacity is limited by the thermal characteristics of contacts
and insulating elements which have an upper temperature limit
which should not be exceeded.

Current carrying capacity
Current carrying capacity
The current carrying capacity is determined in tests which are
conducted on the basis of the DIN IEC 60 512 part 5. The current
carrying capacity is limited by the thermal properties of materials
which are used for inserts as well as by the insulating materials.
These components have a limiting temperature which should not
be exceeded.
The relationship between the current, the temperature rise (loss
at the contact resistance) and the ambient temperature of the
connector is represented by a curve. On a linear co-ordinate
system the current lies on the vertical line (ordinate) and the
ambient temperature on the horizontal line (abscissa) which ends
at the upper limiting temperature.
In another measurement the self-heating (∆t) at different currents
is determined.
At least 3 points are determined which are connected to a parabolic
curve, the basic curve.
The corrected current carrying capacity curve is derived from this
basic curve. The reasons for the correction are external factors
that bring an additional limitation to the current carrying capacity,
i.e. connectable wire gauge or an unequal dispersion of current.
Example of a current capacity curve
Definition: The rated current is the continuous, not interrupted
current a connector can take when simultaneous power on all con-
tacts is given, without exceeding the maximum temperature.
Example of a current carrying curve
Acc. to IEC 61 984 the sum of ambient temperature and the tem-
perature rise of a connector shall not exceed the upper limiting
temperature. The limiting temperature is valid for a complete con-
nector, that means insert plus housing.
As a result the insert gives the limit for the temperature of a com-
plete connector and thus housings as well.
In practice it is not usual to load all terminals simultaneously with
the maximum current. In such a case one contact can be loaded
with a higher current as permitted by the current capacity curve, if
less than 20 % of the whole is loaded.
However, for these cases there are no universal rules. The
limits have to be determined individually from case to case. It is

Current carrying capacity
Transient current carrying capacity
A transient current in circuits can be generated by switching
operations such as the starting of a motor or a short circuit in a
faulty installation. This can cause thermal stress at the contact.
These short and very high increases cannot be dissipated quickly
and therefore a local heating effect at the contact is the result.
Contact design is an important feature when transient currents are
encountered. HARTING contacts are machined from solid material
and are therefore relatively unaffected by short overloads when
compared to stamped and formed designs. For guidance please
see the table below.
Short circuit carrying capacity
Low currents and voltages
HARTING’s standard contacts have a silver plated surface. This
precious metal has excellent conductive properties. In the course
of a contact’s lifetime, the silver surface generates a black oxide
layer due to its affinity to sulphur. This layer is smooth and very
thin and is partly interrupted when the contacts are mated and
unmated, thus guaranteeing very low contact resistances. In
the case of very low currents or voltages small changes to the
transmitted signal may be encountered. This is illustrated below
where an artifically aged contact representing a twenty year life is
compared with a new contact.
In systems where such a change to the transmitted signal could
lead to faulty functions and also in extremely aggressive environ-
ments, HARTING recommend the use of gold plated contacts.
Below is a table derived from actual experiences.

Cross Reference from PG thread to metric cable thread
The Cross Reference table shows the correlation be-
tween the PG versions and the new metric types.
Please notice that the maximum cable diameter will
be reduced by the new metric cable glands.
Below is shown the cable range of metric glands:
The reason for the new product offerings is the publication of the international DIN EN 50262 metric thread
specification. The existing PG series, PG 7 to PG 48 will be, in time, replaced by the metric series M 12 to
M 63.
The adoption of metric threads considerably simplifies the understanding and specification of glands as the
product type description contains the thread dimension. E.g. M 20 refers to 20 mm thread diameter.
To differentiate the metric threaded hoods and housings
from the previous PG versions metric types will be marked with M .
