Filter D-SUB Connectors
One of the standard filters offered by CONEC is the
so-called “C filter”.
Depending on the problem situations, other possible
variations can be employed; a two-stage LC filter and
a three stage PI filter (C-L-C) are also available in various
connector configurations within the standard product line.
CONEC filter connectors are an effective way to guard
against electromagnetic interference (EMI RFI).
