Series 62 Pama F Me GP aca eae Potentiometer Description A precise 10-turn potentiometer offering electrical operating characteristics comparable to units costing far more, Series 62 was designed specifically for the industrial instrumentation market. Series 62 opens new application areas for the inherent advantages of multi- turn potentiometer design. Based upon the setability and resolution of a quality ten-turn potentiometer, Series 62 includes better instrument control and settings for all types of electronic equipment. Features *Setability - 10 turns of resolution Stability - Temperature Coefficient of +20 ppm/C *Linearity range of +0.25 - +0.50% * Long life - 100,000 shaft rotations 102 Series 62 Electrical Specifications Working Voltage 450 Volts maximum (power not to exceed rating) Resistance Range 100 to 100KQ, standard Resistance Tolerance +5% standard; +3%, special Linearity-Absolute 100KQ to 500Q +0.25%, standard.
