Rotary Potentiometers and Rheostats are commonly used components of circuits for measuring and controlling resistors.

PDB181-E420K-102B belongs to the series of rotary potentiometers. It is mainly used for electronic circuits. As a process of achieving its functions, the PDB181-E420K-102B first uses a resistive component and a single finger to complete the electrical connection. Then when the single finger moves along the resistive component, the resistance of the circuit changes. Its working principle is simple, and the knowledge of the application field is useful for DIYers to use.

Due to its specific structure and unique features, this type of potentiometer has a wide range of applications. It is mainly used as an adjustable electronic component to control electro-mechanical equipment. It can also be used to measure the speed of a rotating object, or to measure the angle of rotation, or to adjust the volume on an electronic device. It can also be used to adjust the speed of a motor or as a throttle control, making it a versatile and multi-purpose product.

In addition, PDB181-E420K-102B has been widely adopted in many electronic tools, such as audio amplifiers, security systems, transmitter circuits, foot switch controls, and so on. The compact size and easy operation makes it a popular choice for DIYers and experts alike.

Rheostats, on the other hand, are often used in power distribution applications. Instead of a resistive element, rheostats use resistors or inductors to provide infinite adjustable current. The output of the rheostat is controlled by the position of a knob. By turning the knob, the user can adjust the output current from zero to a maximum amount.

Rheostats are typically used as load-line resistors, AC voltage controllers, current switches, regulators and adjustable voltage dividers. They are also commonly used to control motor speed, dimmers, and in high-power applications such as welding. In general, rheostats are the most common choice for high-power adjustable current devices.

PDB181-E420K-102B rotary potentiometers and rheostats are used in different applications, and different technologies are employed to achieve the desired output. However, they all function to measure and control resistors. DIYers and professionals alike can benefit from having knowledge of the application fields and working principles of rotary potentiometers and rheostats.
