They are manually adjustable variable resistors and work on the principle that potential dropped between two points in a wire of uniform cross section is directly proportional to the distance between the points. Potentiometers are used in manual controls, injection molding machines, woodworking machinery, printing, spraying, machine tools, robotics, engineering, computer-controlled monitoring of sports equipment and other applications requiring precise measurement of displacement. 73JA10K Potentiometer from Honeywell features 10-turn construction with wirewound element and robust nickel-plated brass shaft and bushings. This Honeywell variable resistor is a precision potentiometer with 10K ohm resistance, 2 W power rating, 5 % tolerance and has a rotational life of 50, 000 cycles.
