Chemical-resistant Cover (NT20-KBA01)

cone rubber.
The protection the cover affords is summarized below.
For information on protection against chemical agents not included in the table above, please ask OMRON. (If
it is a chemical agent to which silicone rubber is recognized to be resistant, the cover can be used with confi-
dence even if that chemical agent is not listed in the “Protects Against” column above.

(2) Since the cover is milky white, it reduces the clarity of the display a little.

agents. It will not provide protection against chemical agents that enter through the installation panel
or through the gap between the cover and the display.
