Introduction to Rotary Potentiometers, Rheostats

Rotary potentiometers, also commonly referred to as rheostats, are components used in many electrical and measuring applications. Potentiometers are widely used to measure and control electrical signals, and they are an essential part of many electronic applications. Therefore, understanding their basics, such as their application field and working principle, can be an important step in proper product selection and application.

The Application and Working Principle of the 1-1624200-3 Potentiometer

The 1-1624200-3 is a three-wire rotary potentiometer with a maximum rating of 400 mA. The resistance is adjustable up to a maximum of 5kΩ and its ohmic range is 0.7mm. It is a potentiometer made with thick-film technology which makes it suitable for use in humid condition and able to shun high frequencies.

As one of its main applications, the 1-1624200-3 can be used in variable voltage and current source circuits. It helps adjust the output voltage or current of the circuit to the ideal level. The adjustable resistor core provides resistance against the current. As the amount of resistance changes, the output voltage or current is adjusted accordingly by the controlling circuit.

Working Principle

The working principle of the 1-1624200-3 rotary potentiometer is based on an adjustable resistor core. The end connections of this core are fixed to a pair of terminals, while a wiper terminal is in contact with a track of resistor material. As the rotary knob is turned, the wiper terminal is moved along the resistor track to provide adjustable resistance to the electrical current passing through it.

By adjusting the rotary knob, the resistance of the resistor core can be adjusted between its minimum and maximum value. As the resistance changes, the input voltage to the controlling circuit is also modified, and this can be used to adjust the output current or voltage.

Conclusion

In conclusion, the 1-1624200-3 is a rotary potentiometer used mainly in variable voltage and current source circuits and other electrical and measuring applications. The core of the rotary potentiometer is constructed from an adjustable resistor, and the resistance of this resistor is adjusted between its minimum and maximum value by turning the rotary knob. The modified input voltage then adjusts the output voltage or current. It is a simple yet effective electrical component for many applications.
