Rotary Potentiometers and Rheostats

Rotary potentiometers and rheostats are two versatile pieces of electrical equipment that are used in a variety of applications. The 3590P-2-201L is a particularly popular model due to its reliable performance and cost effectiveness. In this article we will look at the application field of the 3590P-2-201L and the working principle of both rotary potentiometers and rheostats.

Application field of 3590P-2-201L

The 3590P-2-201L is a variable resistor that can be used in different types of electrical circuits. It can be used in audio systems, measuring instruments, and other types of electronics to control the current in a circuit. The 3590P-2-201L has a high operating temperature range of -40°C to +85°C, so it is suitable for use in demanding environments. It is also very durable and can withstand shock and vibration. Additionally, it is very cost effective and can be used in high-volume production.

Working Principle of Rotary Potentiometers

Rotary potentiometers work by using a wiper that moves along the resistor’s track as it is turned. As the wiper moves, it changes the resistance of the circuit and this change in resistance is what allows the potentiometer to control the amount of current in the circuit. This is done by adjusting the voltage divider ratio between the fixed resistor and the variable resistor. The voltage divider ratio is what determines how much current gets to the load in the circuit.

Working Principle of Rheostats

Rheostats work in much the same way as rotary potentiometers, but the difference is that they use a two-wire connection instead of a three-wire connection. Like the rotary potentiometer, the rheostat uses a wiper to adjust the resistance in the circuit. The rheostat’s two terminals are connected to either end of the resistor and the wiper is connected to the middle of the resistor. When the wiper is adjusted, the resistance of the circuit is changed and this is what allows the rheostat to control the current in the circuit.

Conclusion

The 3590P-2-201L is a very popular piece of electrical equipment that can be used in a variety of applications. It is highly durable, cost effective, and can withstand high temperatures. The working principle of both rotary potentiometers and rheostats is based on the same underlying principle of using a wiper to adjust the resistance in the circuit which in turn is used to control the current. This makes them versatile pieces of equipment that can be used in a multitude of different applications.
