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 Determined by resistance value and wattage rating Resistance Taper Standard:Linear taper only Minimum Resistance At ends of rotation: 1% or 1 ohm, whichever is greater 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 Rotational Torque 1/ 2 to 10 inch ounces (36 – 720 gf-cm) Terminals Terminals at end of CW or CCW rotation may be omitted. Refer to terminals on all types by numbers 1 and 3 as indicated on line drawings.
