Appendix
Technical Terms
The explanations of the most important
technical terms used in the catalog rely
heavily on explanations given in VDE
0627 (DIN EN 61984). Please consult
this standard should you require more
detailed descriptions than those given
here. All explanations refer to
connectors.
Connector
This must be differentiated from the
term plug or plug-in socket device. A
connector is a component to which
electrical conductors (cables) are
connected in order to connect these to,
or disconnect them from, another
component or device. When used in
Test voltage (see also IEC 664-1)
The term test voltage is used
synonymously with the term rated surge
voltage. It refers to the defined capability
of the insulation to withstand anticipated
surge voltages. The impulse withstand
voltage is the highest peak value of a
surge voltage with a specified
characteristic (n x KV (1.2/50 μs) which
does not cause insulation breakdown
under defined conditions.
Surge voltage category
(see also IEC 664-1)
Classification of electrical device
(connector) according to anticipated
surge voltage state. There are 4 surge
Degrees of protection
(DIN VDE 0470-1; EN 60529)
The degree of protection of housings is
specified according to an “IP”
classification. In the case of connectors,
this specification is designed to ensure:
? Protection of persons with regard to
access to dangerous parts (touch
protection).
? Protection of the connector with regard
to the ingress of solid foreign bodies
(protection against ingress of solid
foreign bodies).
? Protection of the connector with regard
to damage caused by the ingress of
water (protection against water).
accordance with their designated use,
connectors must not be inserted or
withdrawn under voltage.
voltage categories. The category class
depends on the level of the nominal
voltage (operating voltage) and the

Insertion/withdrawal cycle
An insertion/withdrawal cycle refers to a
connection and disconnection procedure
in the isolated, off-load state.
Upper limit temperature, lower limit
temperature (temperature range)
Maximum permitted temperature at
which a connector may be operated. It
includes the increase in temperature of
the contacts caused by electricity and
the ambient temperature.
Nominal voltage
The term nominal voltage is used
synonymously with the term rated
voltage. Rated voltage is the voltage
used for dimensioning connectors.
Some operating properties are defined
with reference to this.
The equation specified in the data sheet
between effective AC voltage value U rms
(where U max = 1.414 x U rms ) and the
DC voltage refers to the electrical
transmission capacity.
Nominal current
The term nominal current is used
synonymously with the term rated
current. The rated current is the current
which the connector can carry
continuously (without interruption) at an
ambient temperature of 25°C and which
flows through all the connector contacts
which are connected to the largest
possible conductor. The upper limit
temperature is not exceeded.
amplitude depending on the given
design (1.2/50 μs).
Surge voltage category II:
Connectors for applications in systems
or system parts for which lightning
protection voltages do not need to be
specified.
Surge voltage category III
Connectors for applications in systems
or system parts for which lightning
protection voltages do not need to be
specified, but for which special
requirements are defined regarding the
safety and availability of the connector.
Contamination class
(see also IEC 664-1)
Specification of a numeric value (1 to 4)
for a category/class which characterizes
the contamination to be anticipated in
the immediate vicinity of the connector.
Accumulations of solid, liquid or gaseous
foreign matter cause a decrease in the
breakdown strength or surface
resistance of the insulation. The
contamination class depends on the
rated voltage and the material used. This
is used to calculate the minimum values
for the air and creepage distances which
are incorporated in the dimensioning of
the connector.
Protection against
foreign bodies
0-8 : Water protection
(Optional: A,B,C,D)
(Optional: H,M,S,W)
Example: IP66/67:
Touch protection: Protection against
touching a wire
Protection against foreign bodies: Dust-

Water protection: Protection against
powerful jetting and temporary
immersion in water
