EMC-compliant assembly
Assembly instructions for screened cables
with metal-encapsulated round plug
connectors (only for 4-pin plug connectors
C1851)
The more demanding and complex electronic devic-
es become, the higher the requirements in relation
to electromagnetic compatibility (EMC). Only devices
that are free of electromagnetic interference will
provide trouble-free operation.
The connectors on the device input and output
can be a key element for an optimal EMC solution.
Screened connectors that reduce radiated effects
and remove conducted interference are the ideal
solution. Round plug connectors with symmetrical
pin assignments and all-metal housings are positively
predestined for this purpose. The screen function
can be optimally implemented in this case.
NOTICE
In case of assembly with screened cables, the
degree of protection changes to IP65.
