Rotary Potentiometers, Rheostats

A rotary potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. A rheostat is a two- terminal adjustable resistor. 7386R100L.5 is a type of rotary potentiometers.

Application Field

7386R100L.5 rotary potentiometers are used in a variety of fields, including audio control equipment, medical instruments, industrial automation, and aerospace. In audio control equipment, the 7386R100L.5 is used to control the level of sound. In medical instruments, it is used to control the intensity of signals. In industrial automation, the 7386R100L.5 is used to measure and control temperature, pressure, and other industrial parameters. In aerospace, the 7386R100L.5 is used to measure the angle of deflection of ailerons and rudder.

Working Principle

The working principle of the 7386R100L.5 rotary potentiometer is based on the principle of a voltage divider. When the shaft of the rotary potentiometer is rotated, the sliding contacts move across a resistance track with a fixed resistance value. The shaft is connected to a moving contact called the wiper. As the wiper moves across the resistance track, it divides the circuit into two parts. One part is between the wiper and one fixed terminal and the other part is between the other fixed terminal and the end of the resistance track. The ratio between the voltage drop across the two parts is determined by the position of the wiper. This ratio describes the voltage division ratio of the potentiometer.In the case of the 7386R100L.5 rotary potentiometer, the resistance track is a circular arc, meaning that the resistance track is shorter in the middle and longer at the ends. This characteristic allows the 7386R100L.5 to provide a more linear voltage division ratio than standard linear tracks. The 7386R100L.5 also has a long resolution of 500 parts per rotation, providing more accuracy and finer settings than most rotary potentiometers.

Conclusion

7386R100L.5 rotary potentiometers are used in a variety of fields, including audio control equipment, medical instruments, industrial automation, and aerospace. The 7386R100L.5 works by dividing the circuit into two parts using a sliding contact along a circular arc resistance track. This curved track allows for more linear voltage division and more accurate settings.
