presence of EMI and that they do
not emit interference that would un-
duly affect equipment in their envi-
ronment. The Directive has caused
an increased demand for shielding
product and filters. If you are in any
doubt about the effect of this Direc-
tive contact a GAMBIA Enclosure
Group member for clarification.
Enclosures themselves are outside
the scope of the EMC Directive since
they neither produce not are sus-
ceptible to EMI. They do not have
to carry the CE mark as far as the
EMC Directive in concerned.
The table below lists the coatings
to choice, their values and the val-
ues of the gaskets used.
Ensto offers as standard 12 dif-
ferent enclosure sizes with nickel co-
ating in base and cover and a gas-
ket of silver/silicone. Other sizes are
available upon request.
