Rotary Potentiometers, Rheostats

KA1031S28 is a rotary potentiometer and rheostat. It is a two-terminal passive device used for adjusting current in an electric circuit. The device is composed of a resistive element, usually wound wire or carbon film, which when turned around a shaft changes the resistance between its terminals. The amount of resistance change is determined by the rotation angle of the shaft and the type of the device.

Rotary potentiometers are typically used as a variable voltage divider for amplitude modulation. Potentiometers can also be used as an input device to adjust parameters in electronic circuits and mechanical systems. For example, they can be used to adjust the level of a signal or to adjust the speed of a motor. They are also used to adjust the brightness of a display or the volume of a sound.

Rheostats are used for more general applications, such as regulating the current in electrical circuits and controlling the speed of motors. They are typically used to control the amount of current that flows through a circuit or to provide a variable voltage to a device. Rheostats are also commonly used in AC circuit control applications.

The KA1031S28 is a rotary type potentiometer and rheostat. It is rated for 10K Ohm resistance and has a 25 turn range. The device has an all metal construction with a metal shaft and molded plastic knob and body. The shaft rotation is 25 turns through an angle of 270 degrees with spacing of every 10 degrees. The device comes with a built in switch for switching between different resistance values.

The KA1031S28 is designed for use in medium power applications such as audio and video equipment. It is typically used to adjust resistance in circuits where precision and reliability are needed. The device is also designed to be used in high voltage applications up to 600V AC and can be used for controlling the speed of motors.

In conclusion, the KA1031S28 is a versatile rotary potentiometer and rheostat. It is designed for use in audio and video equipment as well as general applications such as controlling the speed of motors. The device is rated for 10K Ohm resistance and can be used for high voltage applications up to 600V AC.
