Rotary Potentiometers

A rotary potentiometer is an electrical device whose resistance varies with a rotation of a spindle or a wiper along its axis. It is an electrical component responsible for controlling the flow of electric current by adjusting the resistance in a circuit. It is commonly used to control the output voltage of an audio source, measure progress in an industrial machine, or even to adjust the frequency of an oscillator.Rotary potentiometers are a type of variable resistor and can be used for a variety of applications such as dimming lights, controlling the speed of a motor, or sensing the pressure of a liquid. They come in varying sizes and shapes depending on the application and can be digital or analog. Digital potentiometers are used in devices to save power and space, and they can also include additional features like temperature control, noise suppression, and memory functions.

392055M8814 Application Field and Working Principle

The 392055M8814 is a rotary potentiometer with a 9mm shaft and a solid body. It is a precision, multi-turn potentiometer designed for manufacturing and process control applications. This device is built to ensure the highest accuracy and stability even in the harshest environments. It is constructed with a stainless steel housing and a heavy-duty, reinforced rotor, making it perfect for outdoor or higher vibration environments. The 392055M8814 comes with a range of options, including shaft and body styles, terminal positions, bushing and wiper designs, and power rating options.The 392055M8814 operates on the principle of a variable resistor. When the shaft is turned, the wiper moves along the resistive track changing the resistance between the two terminals, thereby regulating the current flow. The three terminals, also known as “The Wiper”, “A” and “B”, can be used to measure the output voltage depending on the application. The 392055M8814 is generally used in applications where precise adjustment and accuracy is needed, such as in audio and lighting equipment.Rheostats

A rheostat is a type of variable resistor, similar to a potentiometer, used to control the flow of electricity in an electrical circuit. It consists of a single resistance element which can be adjusted manually to increase or decrease current flow. Rheostats are commonly used to control the speed or current of electrical motors, and they can also be used to alter the dimness of lights or the frequency in AC circuits. Unlike potentiometers, rheostats are generally not used to measure the current flowing in a circuit. They are typically used for controlling the amount of current passing through an electrical circuit or for controlling the speed of an electric motor. Due to their design, they are typically more durable than potentiometers and are capable of handling much larger currents. In summary, rotary potentiometers and rheostats are both devices used to control the flow of electricity in an electrical circuit. The 392055M8814 is a type of rotary potentiometer specifically designed for use in precision applications. It operates on the principle of a variable resistor and is constructed with a stainless steel housing and a heavy-duty reinforced rotor. Rheostats, on the other hand, are used primarily to control the amount of current passing through a circuit and are typically more durable than potentiometers.
