Rotary Potentiometers, Rheostats

P160KN-0E15B25K is a rotary potentiometer (also known as a “pot”) which is used to adjust the resistance between two points in an electrical circuit. It consists of a flat circular base with two terminals – one connected to a contact on the base, and the other connected to a movable arm that rotates about its center. The resistance is adjusted by rotating the arm, which in turn moves the contact on the base to change the relative distance between the contacts.

Application Field

Rotary potentiometers are used in many applications, such as volume controls in audio equipment, lighting controls, and motor speed controllers. They are also used in laboratory instruments and medical equipment.

Working Principle

The working principle of a rotary potentiometer is based on the principle of a variable resistor. When the contact arm is rotated, the resistance between the two terminals changes as the contact moves away from or closer to the base. This change in resistance affects the current flow through the circuit, allowing the user to adjust the current flow to and from the desired level.

To measure the angle of rotation, the rotary potentiometer is often equipped with a mechanical stop or “detent” which is triggered when the contact arm is turned past a certain angle. This allows the angular position of the contact arm to be accurately determined.

Conclusion

Rotary potentiometers, such as P160KN-0E15B25K, are versatile components used in a wide variety of applications. They are simple and efficient tools for adjusting current flow in electrical circuits, and are often used in combination with other components such as resistors and capacitors.
