Hi Reg,
Trying to find a bulkhead RJ45 (shielded & filtered) connector for an EMC
chamber may prove to be an
impossible task as, IMHO, this type of connector might be fairly fragile and
hard to install for
such use. To that end, I will offer some suggestions:
1. Talk to chamber manufacturers. I am quite sure that they would know about
such a connector if one
exists.
2. A bulkhead mounted DB25 connector might work. These can come filtered,
however, the filtering
involved should not impact the communication speeds you will be working with.
To connect to standard
ethernet cables, use 2x(DB25-RJ45) adapters (1 inside & 1 outside). The whole
thing would be
connected as "Outside Cable - Adapter - Bulkhead DB Connector - Adapter -
Inside Cable". These
adapters are quite common and shouldn't need to be filtered as the DB
connectors would do that and
if extra filtering is needed, a simple clip-on ferrite might be all that's
needed (the ferrite might
even be put inside the adapter backshell). And, the DB25 connector might be
used for other
interfaces during testing, as well.
3. You shouldn't need any connector if your EMC chamber has a ventilation
opening. Just fit a cable
thru the opening and put enough ferrite around the cable (inside and outside)
to suppress any common
mode interference.
These suggestions are intended to get all those neurons firing to think of some
connector
alternatives to the one you're seeking. I hope this helps.
Comments anyone? Bring on the flames. :-)

Ron Pickard

Reg,
Look at Regal Electronics at http://www.regalusa.com. They have board
mounted RJ-45 that have gasketing appropriate for a panel.

Subject: RE:RJ45 filtered connector
To All,
Can anyone out there tell me where I would be able to purchase a fully
shielded and filter
RJ45 connector that is Bulkhead mountable.
The RJ45 must be able to handle data rates from 10Base T to 100Base T
I will be performing CE testing in the chamber so it must be bulkhead
mountable !
Thanks and Happy Holidays to YOU ALL !
Reg
