2 POT PROTOTYPES PRONTO! Now almost any special combination potentiometer you specify can be manufactured and shipped soon after your order is received. Since larosystem and Mod Pot potentiometers are modular in construction, we can produce prototype quantities of / or 5/8 inch square, conductive plastic, cermet, or hot molded carbon pots for you in just a few hours.... and even production quantities in a matter of days with our VIP (Very Important Potentiometer) service! Over one billion combinations of single, dual, triple, quad arrangements, push-pull or rotary switches and hundreds of shaft terminal variations can be produced. If you need a potentiometer and you need it fast, call our product manager or fax us your requirements using the ustom Potentiometer Order Form included in this catalog.

34 SERIES 88, 89 GLOSSRY OF TERMS Input and Output Terms Output Voltage (e) The voltage between the wiper terminal and the designated reference point. Unless otherwise specified, the designated reference point is the W terminal (See.). Figure ircuit and Travel Diagram Electrical Overtravel - Nonwirewound The shaft travel over which there is continuity between the wiper terminal and the resistance element beyond each end of the Theoretical Electrical Travel. Electrical ontinuity Travel The total travel of the shaft over which electrical continuity is maintained between the wiper and the resistance element. Tap Location The position of a tap relative to some reference. This is commonly expressed in terms of an Output Ration and/or a shaft position. When a shaft position is specified, the Tap Location is the center of the Effective Tap Width. Resistance W End Resistance The resistance measured between the wiper terminal and an end terminal with the shaft positioned at the corresponding End Point. W Terminal enter Terminal W Terminal Temperature oefficient Of Resistance The unit change in resistance per degree celsius change from a reference temperature, expressed in parts per million per degree celsius as follows: Output Ratio (e/e) The ratio of the output voltage to the designated input reference voltage. Unless otherwise specified, the reference voltage is the total applied voltage. Rotation and Translation Total Mechanical Travel The total travel of the shaft between integral stops, under the specified stop load. In potentiometers without stops, the mechanical travel is continuous. Mechanical Overtravel - Wirewound The shaft travel between each End Point (or Theoretical End Point for bsolute onformity or Linearity units) and its adjacent corresponding limit of Total Mechanical Travel. Mechanical Overtravel The shaft travel between each Theoretical End Point and its adjacent corresponding limit of Total Mechanical Travel. acklash The maximum difference in shaft position that occurs when the shaft is moved to the same actual Output Ratio point from opposite directions. Theoretical Electrical Travel The specified shaft travel over which the theoretical function characteristic extends between defined Output Ratio limits, as determined from the Index Point. Where: R = Resistance at reference temperature in ohms. R = Resistance at test temperature in ohms T = Reference temperature in degrees celsius. T = Test temperature in degrees celsius. onformity and Linearity Linearity specific type of conformity where the theoretical function characteristic is a straight line. Mathematically: e E T.. = R R R (T T ) = f(w) ± = (W) + ± x 06 Where: is the given slope; is given intercept at W=0. W = ngle or slope bsolute Linearity The maximum deviation of the actual function characteristic from a fully defined straight reference line. It is expressed as a percentage of the Total pplied Voltage and measured over the Theoretical Electrical Travel. n Index Point on the actual output is required.
