Rotary potentiometers and rheostats are two different types of variable resistors which are used very frequently due to their versatility. The RUS400 is a specific type of variable resistor, popularly known as a rotary potentiometer. It is used mainly in applications where an adjustable level of resistance is needed, such as in light dimmers or audio controls.

The construction and working principle of the RUS400 is fairly simple and straight forward. It is a carbon track resistance which comprises of a wiper arm which is attached to a rotating shaft. The three terminals of the device are connected to a piece of carbon track which is laid out in a circular pattern at the same level. The wiper arm is connected to the rotating shaft and rotates around the circumference of the carbon track. When the rotor is rotated, the distance between the wiper arm and the carbon contact changes. This change in the distance results in a change in the resistance that is observed at the terminals of the device.

In addition to the adjustable resistance, the RUS400 also offers an additional benefit, that of high resolution. This means that the resistance level can be adjusted in very small increments, making it ideal for applications where a higher level of precision is required. For example, in audio applications, the higher resolution of the RUS400 allows for the adjustment of volume, tone, and other sound parameters in very fine gradations.

The RUS400 is also a versatile device and it can be used in both AC and DC power circuits. This allows the user to make the most of the adjustable resistance feature, and use the device in a variety of different applications. Its small size also makes it very easy to fit in tight spaces, making it suitable for applications such as the tight spaces found in many consumer electronics products.

The RUS400 is a durable device and can withstand a wide range of operating temperatures. The fact that it is relatively low cost when compared to other types of resistors makes it even more attractive. The RUS400 is therefore an ideal choice for applications where adjustable resistors are needed and precise adjustments are required.
