FIXED CONNECTORS
NOMINAL SINGLE CONTACT CURRENT LOAD
TERMINATION CROSSꢀSECTION
WIRE
The current-carrying capacity which each individual contact
can be loaded with on its own ꢀ see page 167ꢁ.
Intended for mounting on a fixed surface such as a frame, dock,
device or wall ꢀ with ODU also receptacle or panel-mounted plugꢁ.
The specified cross-sections correspond to a “fine-wire” con-
ductor structure pursuant to IEC 60228:2004 ꢀ VDE 0295:2005;
Class 5ꢁ or a “fine-wire” conductor structure ꢀ 7/19 wireꢁ
according to AWG ꢀ ASTM B258-14ꢁ.
Wires ꢀ solid conductorsꢁ are available with an insulator sleeve
and/or electrical shielding. Cables or conductors may be made
up of one or more wires.
FREE CONNECTORS
NOMINAL VOLTAGE
Intended for mounting on free ends of mobile leads and cables
ꢀ with ODU also connectors, plugs, in-line receptaclesꢁ.
The voltage which the manufacturer specifies for a connector
and relates to the operating and performance features.
TERMINATION TECHNOLOGIES
Methods for connecting the leads to the electro-mechanical
element, such as solder-free connections pursuant to
IEC 60352 ꢀ DIN EN 60352ꢁ: crimp, screw connection etc. or
soldering connection ꢀ see page 165ꢁ.
INSULATOR
OPERATING TEMPERATURE FOR ODU MINIꢀSNAP
Part of a connector which separates conductive parts with
different potentials from one another; usually identical to the
contact carrier.
Range between the uppermost and lowermost temperature
limits. ꢃ 40 °C to +120 °C ꢀ see page 15ꢁ.
TEST VOLTAGE
OPERATING VOLTAGE
The voltage which a conductor can withstand under defined
conditions without dielectric breakdown or flashover.
KEYING ꢁORIENTATIONꢂ
The nominal voltage of the power source for which the connec-
tor is being used. The operating voltage may not be higher than
the nominal voltage of the connector.
Arrangement with which differing polarization of otherwise
identical connectors prevents interchangeability. This is a good
idea if two or more identical connectors are attached to the
same device ꢀ see also compatible connectors, see pages 39,
88, 125ꢁ.
TIGHTNESS IEC 60529:2013 ꢁVDE 0470ꢀ1:2014ꢂ
See protection classes on page 162.
PCB ꢁA.K.A. “PRINTED CIRCUIT BOARD”ꢂ
A PCB is a carrier for electronic components. It serves the pur-
poses of mechanical mounting and electrical connection.
UPPERMOST LIMIT TEMPERATURE
LOWERMOST LIMIT TEMPERATURE
The maximum permissible temperature at which a connector
may be operated. It includes contact heating through cur-
rent-carrying capacity.
The lowest permissible temperature at which a connector may
be operated. At ODU MINI-SNAP, it amounts to ꢃ 40 °C.
PCB TERMINATION
Production of a conductive connection between the PCB and an
element in through-hole assembly, THT ꢀ through-hole technologyꢁ.
With ODU MINI-SNAP Standard TURNTAC contacts, it amounts to
+120 °C. Please consult ODU for high-temperature applications.
MATING AND DEMATING FORCE
The force required to fully insert or withdraw pluggable ele-
ments without the influence of a coupling or locking device.
RATED CURRENT ꢁNOMINAL CURRENTꢂ
See page 167.
MATING CYCLES
RATED VOLTAGE
Mechanical actuation of connectors and plug devices via push
and pull action. A mating cycle consists of one insertion and
withdrawal action. ODU’s standard value for the ODU MINI-SNAP
series is 5,000 mating cycles.
According to IEC 60664-1:2007 ꢀ VDE 0110-1:2008ꢁ standard
“Value of a voltage which is specified by the manufacturer for
a component, device or operating medium and relates to the
operating and performance features.”
MAX. CONTINUOUS CURRENT
SOLDER CONNECTION ꢁSOLDER TERMINATIONꢂ
The metrologically determined amperage at room temperature
ꢀ approx. 20 °Cꢁ which increases the contact temperature to the
limit temperature. The values specified in the catalog apply to
either individual contacts or completely assembled inserts /
modules, as indicated.
Termination technology in which a molten additional metal
ꢀ solderꢁ with a lower melting point than the base materials to
be connected is used to attach two metallic materials to one
another.
GENERAL NOTE
The connectors listed in this catalog are intended for use in high
voltage and frequency ranges. Suitable precautionary measures
must be taken to ensure that people do not come into contact
with live conductors during installation and operation.
All entries in this catalog were thoroughly reviewed before
printing. ODU reserves the right to make changes based on the
current state of knowledge without prior notice without being
obliged to provide replacement deliveries or refinements of
older designs.
