Electrical and Mechanical Specifications
Resistance Range
1 ohm through 10K ohms (linear taper)
Resistance Tolerance
Standard:±20%
Special:±5% or 10%
Power Rating, Watts
2 watts @ 55°C derated to no load @ 105°C,
mounted on steel panel
1.5 watts @ 55°C derated to no load @ 105°C,
mounted on bakelite panel
Voltage Rating

Resistance Taper
None
Incorporated Fixed Resistor
A fixed resistor can be incorporated in the Series 110
at the end of CW or CCW rotation to a minimum of 10%
of the total resistance. The rotation is shortened by an
amount proportional to the ratio of the fixed resistor to
the total resistance. Available at extra cost.
Angle of Rotation
246°±5°without fixed resistor stop
Resistor Adjustment
Standard Cross Slot: Provided in drive plate for screwdriver
adjustment.
Special Molded Knob: Available at extra cost secured to
drive plate cross slot.
Mounting Types Available
Type 110:
Solder or clinch-ear mounted
Type XPC - 110: Vertically mounted on printed circuit board
Type 111:
Snap-in mounting
Type 112:
Eyelet or rivet mounting
