Material properties
All metal parts of the COMBI connectors
are made from corrosion-free materials.
The distinction between the electrical and
mechanical functions is a particular
advantage. The conductive metals consist of
high-grade copper alloys. The surface of the
metal parts is protected by lead-free,
galvanic nickel or tin plating. The high
current carrying capacity of the contact is
achieved by an integrated covering spring
made of chromium-nickel spring steel.
The insulating housing of the COMBI
connectors is made from recyclable PA6.6.
This elastic plastic with high impact strength
is halogen-free and UV resistant. Further
characteristics include the good tropical and
termite resistance, high chemical resistance,
and excellent aging characteristics.
Polyamide 6.6 can be used with operating
temperatures up to 130°Cand is certified
for inflammability class V0 according to
UL94.
Connection principle
COMBI plug-in connections are designed
for the most stringent universal demands in
terms of plug-in capability. Here the nominal
current of the connected conductor can be
carried through the plug-in contact.
The uniform plug-in zone is an important
characteristic. Connectors and basic
terminal blocks with four connection
technologies can be freely combined with
each other, thanks to the uniform plug-in
zone.
The modular structure also enables
individual self-assembly of the plugs and the
couplings.
All kinds of copper conductors can be
connected without any pretreatment.
Splicing protection can also be implemented
in the form of ferrules.
COMBI connectors with all connection
technologies offer a large insertion space,
i.e., conductors with ferrules and insulating
collars and with a nominal cross section can
also be wired.
