EMC Filtering question

Hi,

I am in the process of adding a relay driver board as a 'daughter
board' to an existing design/enclosure. I have to take the (isolated)
relay contact connections to a new connector in the enclosure, for
connection to (goodness knows what in) the outside world.

I'd like to take some precautionary measures to attenuate any h.f.
that may propogate into my enclosure via the relay contact wires, but
I'm unsure as to what is the best practise for this- The connector is
PCB mounting, and so the usage of ferrite beads might be difficult.
Any suggestions?


Thanks 

David
