Potentiometers having conductive polymer tracks are tested as potential
dividers with a wiper load resistance of a minimum of 100 times
the track resistance.
The wiper contact must only be used to pick up the control voltage,
so also absolute care must be taken, when connecting the wires not
to make any mistake.
The pin must not take any radial forces, so you can either use the
potmeter as in the example given here or some other bearing application
with rotatable fixings of the potmeter, etc. Also important are
the upper and lower limit (bump stop's) not to overload mechanically
