TRIMPOT®POTENTIOMETER
PANEL MOUNTING OPTIONS
AND HARDWARE
Many Trimpot®Potentiometers are avail-
able for panel mount application.
This product option provides for maxi-
mum design flexibility.
To order Trimpot®Potentiometers with
panel mount hardware attached by the
factory, simply add an “M” or “Z”
suffix to the Bourns part number per
Table I, page 75.
Example:
3006P-1-100Z
To order military Trimpot®
Potentiometers with panel mount hard-
ware attached by the factory, order the
military part number and add “with panel
mount attached.”
Example:
RT12C2PRC, with panel mount
attached.
To order panel mounting accessories for
customer installation, simply use the part
number per Table II, page 75.
Example:
H83P
NOTE: For complete product specifica-
tions, see catalog page for the trimmer
model.
