Shielding Effectiveness
Results shown are typical for a standard Grayhill
Series 84S Keyboard. A conductive gasket will
generally increase the shielding, depending on
the size and shape of the gasket and its material.
Data derived for E-Field Radiation.

receiving equipment. A signal generator provided
the frequency source that was radiated from the
transmitting antenna to the enclosed receiving
antenna. The spacing between antennas was
maintained constant throughout the frequency
range. The effectiveness rating is determined
by establishing a reference reading without
obstruction between the two antennas and
determining the difference between that reading
and the test setup reading.

Library of Legends
Adding Color
Grayhill maintains a legend library which contains
the most often requested special legends and
many unusual ones. If the legend is in the library,
the cost to utilize this legend in your keypad
configuration is minimal. If the legend is not
available, Grayhill can list the charges required
to add your legend to the library. In this manner,
new legends are added on a periodic basis.
Custom legends to fit your unique requirements
may not be as expensive as you think, contact
Grayhill.
Use colored buttons to segregate button
groupings or to provide originality. Available in
black legends on white or yellow buttons, or
in white legends on black, green, red or blue
buttons. Two popular combinations, black on
white and white on black, are available from
Grayhill stock. Delivery time will increase for
other color combinations.

Keyboards and Keypads
Note:
When measured in actual equipment, shielding
effectiveness is determined by many factors.
This method accurately represents the shielding
effectiveness of the Grayhill Series 84S under
ideal test conditions.
Test Method:
Measurements were made with the keyboard
mounted to a brass plate, which in turn was
mounted to a shielded enclosure containing the
Mouser Electronics
