Terminal Information
Across end terminals
Determined by resistance value and wattage rating
Grounded Construction — The grounded construction is
supplied without a center terminal and the contactor is
connected to the case. This construction can be furnished
with one end terminal at either end of the resistance
element or with terminals at both ends of the element.
Resistance Taper
Linear (±ꢀ5 independent linearity% standard)
Taps
Insulated Construction — The contactor is insulated from the
base and connected to the center terminal on the insulated
construction. This construction can be supplied with the
center terminal and one end terminal at either end of the
resistance element or with the center terminal and terminals
at both ends of the resistance element.
None
Incorporated Fixed Resistor
A fixed resistor can be incorporated in the Series 11±
at the end of CW or CCW rotation to a minimum of 1±5
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.
Rotational Torque
Turning Torque: 1/2 to 10 inch-ounces (ꢀ6 – 720 g-cm)
Stop Strength: 4 inch-pounds (4.6 Kg-cm)
Angle of Rotation
270° ± ±°
