Rotary Potentiometers, RheostatsThe 5311R30KL.5 is a type of radial-lever rotary potentiometer, also known as a rheostat. This mechanical device is used to measure resistance variations formed from the relationship between the angle of rotation and wiper current. It is typically composed of carbon or wire wound resistors.Rotary potentiometers are used in many industries and devices, including those used in the medical, automotive and industrial sectors. They are used as variable controls for devices such as audio amplifiers, appliances, fans, motors, light dimmers, and toys.These components perform a variety of tasks. In the context of automotive and industrial applications, their purpose is to measure and control the speed of motors. In the context of audio amplifiers and home appliances, they can be used to adjust sound levels, fan speeds, and other components. They can also be used in industrial and medical applications to regulate the flow of electricity in medical devices or test equipment. They are also used frequently in the production of circuit boards to alert staff to changes in production conditions.The 5311R30KL.5 has two perforated contact discs, one on either side, that depend on the application and form the basis for the resistances created. A rotary lever is connected to the housing which rotates with the resistance adjustment of the rotary element. Depending on the angle of rotation, the lever will move from one end of the resistance curve to the other. The resistance applied to the circuit is determined by the linear movement of the rotary lever. The link between the angle of rotation and the resistance formed is specified by the manufacturers of the components and is referred to as the characteristic curve. In most cases, the characteristic curve will show a linear relationship between the resistance value generated by the rotary potentiometer and the angle of rotation. The characteristic curve is typically supplied as part of the component datasheet.In addition to the angle of rotation and the 0−100% resistance range, the 5311R30KL.5 is equipped with a center tap. This component is placed between the two perforated contact discs and allows the angular positioning of the resistance to be altered in an infinite amount of steps, rather than just two. When applied to the circuit, the 5311R30KL.5 is connected in the path of the current. This ensures that a portion of the current is “tapped off” and goes through the component. As the angle of rotation and the associated resistance value change, the amount of current passing through the component will also change. The 5311R30KL.5 is one example of a rotary potentiometer. This type of device is well-suited for applications where resistance must be precisely adjusted over a range of values or when the resistance needs to be continuously varied in response to changes in the environment. In many cases, these components provide a simple and cost-effective solution for controlling the amount of current in a circuit.
