Rotary Potentiometers, Rheostats

RKS25R is a kind of rotary potentiometer and rheostat which are used for several applications. This type of potentiometers and rheostats have a rotatable knob or shaft which expands or contracts a resistance when it is rotated. A mechanical stop limits the rotation angle for normal, uniform operation. RKS25R performs both the linear and angular motion measurements.

Applications

The various applications of the RKS25R rotary potentiometers and rheostats are as follows:

• The RKS25R can be used to measure electric parameters such as voltage and current. It can also be used to measure the speed and position of a motor. It is often used to control motor speed and provide feedback for position control.
• RKS25R is used to control the levels in sound and audio systems. It also adjusts the frequency response of the speaker.
• The RKS25R can be used as an adjustable resistor in many electronic devices such as power supplies, oscillators, and amplifiers.
• In the consumer electronic field, it is used to adjust the brightness and contrast of a TV set or monitor.
• The RKS25R is used in close loop control systems such as automation and robotics.

Working Principle

The key component of the RKS25R rotary potentiometer is a resistor. The resistor consists of two main parts: a resistive track and a wiper. The resistive track is a circular strip or track of resistive material that is wound around a simple axle. The wiper is the movable arm of the potentiometer which slides over the track as it is rotated. The resistance between the wiper and the track increases or decreases depending on the rotated angle.

When the RKS25R is used as a rotary potentiometer, an external voltage is applied across one end of the resistor and the output voltage is taken on the wiper. As the rotary knob is turned, the resistance between the wiper and the track changes and therefore causing a change in the output voltage. The output voltage is directly proportional to the rotation angle of the knob.

When the RKS25R is used as a rheostat, an external voltage is applied across both ends of the resistor and the output current is taken on the wiper. The current is regulated by changing the resistance between the wiper and the track. The output current is directly proportional to the rotation angle of the knob.

Conclusion

RKS25R is a type of rotary potentiometer and rheostat which is used for several applications. It can be used to measure electric parameters, control motor speed, regulate the levels of sound and audio systems, and act as an adjustable resistor in many electronic devices. As a potentiometer, the output voltage is directly proportional to the rotation angle of the knob. As a rheostat, the output current is also directly proportional to the rotation angle of the knob.
