TECHNICAL INFORMATION
TECHNICAL TERMS
FIXED CONNECTORS
Intended for mounting on a fi ed surface such as a frame, dock,
device or wall (with ODU also receptacle or panel-mounted plug).
FREE CONNECTORS
Intended for mounting on free ends of mobile leads and cables
(with ODU also connectors, plugs, in-line receptacles).
INSULATOR
Part of a connector which separates conductive parts with
diff erent potentials from one another; usually identical to the
contact carrier.
KEYING (ORIENTATION)
Arrangement with whic h diff ering 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, 125).
LOWERMOST LIMIT TEMPERATURE
The lowest permissible temperature at which a connector may
be operated. At ODU MINI-SNAP, it amounts to –40 °C.
MATING AND DEMATING FORCE
The force required to fully insert or withdraw pluggable ele-
ments without the infl ence of a coupling or locking device.
MATING CYCLES
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.
MAX. CONTINUOUS CURRENT
The metrologically determined amperage at room temperature
(approx. 20 °C) which increases the contact temperature to the
limit temperature. The values spec
ifi ed in the catalog apply to
either individual contacts or completely assembled inserts /
modules, as indicated.
NOMINAL SINGLE CONTACT CURRENT LOAD
The current-carrying capacity which each individual contact
can be loaded with on its own (see page 167).
NOMINAL VOLTAGE
The voltage which the manufacturer spec ifi es for a connector
and relates to the operating and performance features.
OPERATING TEMPERATURE FOR ODU MINI-SNAP
Range between the uppermost and lowermost temperature
limits. –40 °C to +120 °C (see page 15).
OPERATING VOLTAGE
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.
PCB (A.K.A. “PRINTED CIRCUIT BOARD”)
A PCB is a carrier for electronic components. It serves the pur-
poses of mechanical mounting and electrical connection.
PCB TERMINATION
Production of a conductive connection between the PCB and an
element in through-hole assembly, THT (through-hole technology).
RATED CURRENT (NOMINAL CURRENT)
See page 167.
RATED VOLTAGE
According to IEC 60664-1:2007 (VDE 0110-1:2008) standard
“Value of a voltage which is spec
ifi ed by the manufacturer for
a component, device or operating medium and relates to the
operating and performance features.”
SOLDER CONNECTION (SOLDER TERMINATION)
Termination technology in which a molten additional metal
(solder) with a lower melting point than the base materials to
be connected is used to attach two metallic materials to one
another.
