Rotary Potentiometers

PDB242-E220F-103B0 is an example of a rotary potentiometer. This type of variable resistor is composed of a spindle and a contact wiper which is connected to a resistive element. It also has a fixed contact and a variable contact at the end. As the spindle is turned, the contact wiper moves across the resistive element. This movement changes the resistance that the component provides. It can be used to control a variety of operations in the out-put devices or for measuring the value of the current.

Working Principle

A rotary potentiometer is used to measure or control electrical signals that vary in strength. The device works by using a wiper contact to measure a change in resistance due to a voltage applied across the two contacts on each end of the device. This then allows for an approximate measure of the voltage across the component. When the resistance changes, the voltage changes as well. This allows the rotary potentiometer to be used as a voltage divider. The result of this action can then be calculated to get a value for the current passing through the device.

In addition, rotary potentiometers can also be used to control the current in an electrical device. The working principle is very similar to the voltage measurement usage. As the spindle is turned, the contact wiper moves across the resistive element. This movement changes the resistance that the component provides. By changing the resistance, the current flowing through the electrical device can be regulated.

Application Field

Rotary Potentiometers are widely used in a variety of industries thanks to their versatility and accuracy. In the automotive industry, for example, they are commonly used to control the electrical signal in devices such as sensors. This allows the device to detect changes in pressure, temperature, or other variables. In the aerospace and defense industries, they are used to control the flight of air- and spacecraft, as well as to help with navigation.

In the medical field, rotary potentiometers are used to monitor the electrical signals of the human body. This allows medical professionals to monitor their patients’ vital signs. Finally, they are also used in the manufacturing industries to regulate the speed of machines or conveyor belts.

PDB242-E220F-103B0 is a perfect example of a rotary potentiometer that can be used in any of the above mentioned application fields. With its precision and accuracy, this device is an indispensable part of the modern industry.
