Rotary Potentiometers, Rheostats are widely used as adjustable electrical devices used to regulate current for a variety of applications and for this reason are classified as volume controls, speed, voltage or current regulators. The most common type of rotary potentiometer is the 39SB-1RB-104.

A 39SB-1RB-104 is a three terminal device in which the resistance is varied by rotating the shaft. Commonly used to measure angle, the device consists of a circular track usually made of conductive plastic and a contact which moves along the track as the knob is turned. The contact is spring loaded and always maintains contact with the wiper during rotation, ensuring a steady flow of current. The resistance, measured in ohms, is the difference between the two terminals. The amount of resistance between the middle terminal (wiper) to each of the other two (end) can be varied as the knob is adjusts the contact along the track.

The 39SB-1RB-104 rotary potentiometers are easily adapatable to many different applications due to their high precision and simple operation. It can be easily installed in audio equipment, such as amplifiers, equalizers, radio equipment and even medical apparatus. It is also applicable and used in industrial equipment, such as automatic control systems and measuring devices.

The 39SB-1RB-104 shaft is constructed from a variety of materials, such as aluminum, brass, stainless steel and plastic. Depending on the application, it can easily be adjusted to fit whatever needs are desired. The device can function as a rheostat when the three terminals are connected in series. By connecting the device in this manner, the resistance of the device can be adjusted. This allows the current to be varied by changing the resistance, which is convenient for applications such as controlling the speed of motors.

In summary, 39SB-1RB-104 is a versatile, highly precise rotary potentiometer that is applicable in a wide range of applications such as audio equipment, radio equipment, industrial automatic control systems and motor speed control. From these applications, the device offers a range of benefits. Its simple operation, durability, reliability, and exceptional precision make it an ideal choice for many applications.
