Print contacts
Print contacts are available in straight or elbow versions
for certain connector types, mostly for straight and elbow socket
models. Connection is made on flexible or rigid printed cir-
cuits by soldering.
Straight print contacts are gold-plated which guarantees
optimum soldering, even after long-term storage. However
Test voltage
Test voltage (Ue) :
(measured according to the IEC 60512-2 test 4a standard)
It corresponds to 75% of the mean breakdown voltage.
Test voltage is applied at 500 V/s and the test duration is 1
minute.
This test has been carried out with a mated plug and socket,
with power supply only on the plug end.
Operating voltage (Us) :
It is proposed according to the following ratio : Us =
Caution:
For a number of applications, safety requirements for
electrical appliances are more severe with regard to
operating voltage.
In such cases operating voltage is defined according
to creepage distance and air clearance) between live parts.
Please consult us for the choice of a connector by indi-
cating the safety standard to be met by the product.
Rated current
(measured according to IEC 60512-3 test 5a)
The specified rated current can be applied simultaneously
to all the contacts.
It corresponds with an average temperature rise of 40°C of
the connector.
The current values are indicated in the table of insulator
types in each series.
For use at higher temperatures acceptable rated current
will be lower. It tends towards zero as the material is used
at the maximum operating temperature accepted for the
insulator.
In most case the current depend on the conductor dimen-
sion (see table on page 183) or on the printed circuit dimen-
sion.
Caution:
In general, connectors should not be unmated while
live.

for wave soldering, we recommend removal the gold-plat-
ing from the contact end on the printed circuit side before sol-
dering according to the assembly procedures.
Print elbow contacts include a tinned lead free brass wire
crimped into a crimp contact.
Voltage values are given in the table on insulator types for
each series.
They correspond with values measured at sea level.
They are adapted to all applications up to an altitude of
2000 m.
In case a device is used at a higher altitude, air clearance
between live parts has to be multiplied by the following
coefficients.
It means also that test voltage has to be divided by this
coefficient.
For connectors with PEEK insulator, maximum admissible
current will follow the curve below depending on the oper-
ating temperature T.
