Power Rating, Watts

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

Across end terminals:

Determined by resistance value and

wattage rating

Resistance Tapers

Standard: Linear

Taps Available

None

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)

4 in-oz. (4.61 Kgf-cm)
