Passivation Layer
The standard CA Series is supplied with passivation
layer around the outside perimeter of the disc forming
an electrical insulator as detailed in the dimensional
drawing. For other options contact factory. (See Ordering
Information)
Encapsulated Recommendations
After lead attachment, the disc/lead assembly may be
coated or encapsulated in a package to provide electrical
insulation and isolation from environmental contamination
as required by the application. Coating/Filler materials for
containers may include silicones, polyurethanes, and some
epoxy resins. Materials containing halogens, sulfides, or
alkalines are not recommended.
Stacking and Contact Pressure Recommendations
When applications require the stacking of CA60 discs,
or when an electrical connection is made by pressure
contacts, the pressure applied to the CA60 disc electrode
surface should be minimum 2.2kgs (5 pounds) and
maximum
