Incorporated Fixed Resistor
A fixed resistor can be incorporated in the Series 115
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
270 5
Adjustment of Resistance
Standard: Cross slot provided in rotor for screwdriver
adjustment.
Special:
Molded nylon, screwdriver-slotted shafts which
are integral with rotor are available in many lengths
in increments of

Terminal Information
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.
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.
