2 watts @ 55°C derated to no load @ 105°C,
linear taper, bushing mounted control on
steel panel 4"x4" x .050"
(101.6mm x 101.6mm x 1.27mm).
Voltage Rating
Terminals to mounting surface (insulated types only):
High pot test, one minute — 900 VAC
Operating Maximum — 500 VDC

Incorporated Fixed Resistor
A fixed resistor can be incorporated at the end
of CW or CCW rotation to a minimum of 15% of
the total resistance value. The rotation is
shortened by an amount proportional to the ratio
of the fixed resistor to the total resistance value.
Angle of Rotation
Total Rotation: 270° ± 5°
Rotational Torque
Turning Torque: 1/2 to 10 in-oz. (36-720 gf-cm)
Stop Strength
4 in-oz. (4.61 Kgf-cm)
