Northern Connectors Conec D-Sub Filter Connectors - Manual

In applications where connectors penetrate shielded
enclosures commonly represent a breakdown in
shielding since the connector’s plastic isolating body
provides no shielding against any interference signals
that may be present.
Therefore high frequency interference signals can be
passed in or out of the system without hindrance.
The connector’s contacts act as antennas that receive
and transmit interference signals because filtering is
typically implemented on the PC board.
Interface connectors with integrated filters can be
of benefit in these cases.
CONEC filter D-subminiature connectors contribute
to the protection of EMC zones. The intergrated
filter inside the connector saves PCB-space and
can be installed into an existing PCB layout. To
replace an unfiltered connector into filtered one
is simple and effective.

At increasing data transfer rates and operating frequencies it
becomes increasingly important to safeguard the function of
electrical devices and systems in their interactive relationship so
that operation can be free of interference. This is also the clear
objective of the EMC law.
