3590P-2-203L Potentiometers, Variable Resistors

Rotary Potentiometers, Rheostats

A rotary potentiometer is a three-terminal, continuously adjustable type of variable resistor with a movable contact, or “arms”, that adjust the resistance level between two end terminals by turning a rotary knob. A rheostat operates the same way, but instead of adjusting an electrical signal, it controls the electrical current in a circuit.The 3590P-2-203L is a rotary potentiometer and rheostat that is commonly used in electronics and industrial applications. It is designed to offer a wide range of adjustment and control and is well-suited for use in low voltage and/or low-power applications.

Application Field

The 3590P-2-203L is appropriate for use in commercial, industrial, automotive, marine, consumer electronics, and medical applications. Specifically, it can be used in motorboats, amplified speakers, powered amplifiers, medical instruments, electric fans, power tools, light dimmers, data entry devices, and a wide range of other electronic devices.This potentiometer is particularly useful in applications that require a continuous and precise adjustment of an electrical current. This allows users to dial in the exact level of resistance needed for precise control and operation of their electronic equipment.

Working Principle

The 3590P-2-203L rotary potentiometer and rheostat operate using a simple principle. The potentiometer has a body made of a ceramic material with two end terminals and a rotary knob on the top to control the resistance. When the knob is turned, the contact point between the two end terminals moves, changing the resistance in the circuit. The end terminals can be connected to either a voltage or current source.The rheostat also works on the same principle, but it is used to adjust the current in a circuit, rather than the voltage. When the rotary knob is rotated, the resistance between the two end terminals changes, altering the current that flows through the circuit.Both the potentiometer and the rheostat can be adjusted to provide precise control of either voltage or current in a circuit.

Conclusion

The 3590P-2-203L rotary potentiometer and rheostat are useful components for a variety of different electronic applications. They offer a wide range of adjustment and control and are well-suited for use in low voltage and/or low-power applications. With their adjustable contacts, users can dial in the exact level of resistance or current needed for precise control and operation of their electronic equipment.
