Rotary Potentiometers and Rheostats

A rotary potentiometer or rheostat is a type of component used in electrical circuits that acts as a variable resistor. It can be used to control the amount of current flow in a circuit, as well as to measure the amount of voltage or current being used in a circuit. Rotary potentiometers and rheostats are typically used in electronic devices such as commercial and industrial equipment, home appliances, and electronic test equipment.

One example of a rotary potentiometer is the PDB181-K420K-203B. This type of component is a three-terminal, single-turn, miniature, digitally controlled, rotary potentiometer with a durable contact construction. It is usually used to measure voltage or current in medical, automotive, and industrial applications. Other types of rotary potentiometers are available with different number of terminals, sizes, and contact materials.

The working principle of a rotary potentiometer is based on the same principle as a regular potentiometer. As the knob or shaft of the rotary potentiometer is rotated, one of its terminals is connected to a wiper on the device\'s resistance element. This changes the resistance value within the circuit, allowing currents to be regulated or voltage values to be measured.

Rheostats are a special type of rotary potentiometers that work on a similar principle, but are used specifically to control the amount of current flowing through a circuit. This is usually done by changing the resistance of the device’s resistance element as the knob or shaft of the rheostat is rotated. Rheostats are usually used to control motor speed, as well as in applications such as power supplies and battery chargers.

Rotary potentiometers and rheostats are widely used in a variety of commercial, industrial, and residential applications. They can be used to regulate the voltage or current of a circuit, as well as to measure it. For instance, they can be used in medical equipment, automotive systems, industrial control systems, home appliances, and electronic test equipment.
