Rotary Potentiometers, Rheostats

Potentiometers and rheostats are devices used to measure and control electric current. Potentiometers are considered active components, meaning they act as transducers, while rheostats are labeled as passive components, meaning they only resist rather than transform electrical energy. Both types of devices serve important, but distinct, roles in circuit design. A Potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. Potentiometers are often used to dynamically adjust electrical signals. The varying resistance creates a voltage drop which is proportional to the displacement of the wiper. It can be used as a variable resistor to adjust the sensitivity of an electrical circuit or to control the volume of audio outputs. The KKA1021S28 Potentiometer is a standard 28mm potentiometer with a sealed die-cast body. It features an adjustable conductive plastic element which allows the user to modify resistance by rotating the knob. By providing a smooth transition from low to high resistance, it is capable of controlling a wide range of signals. The KKA1021S28 has a maximum power of 0.25W, a maximum voltage of 10V and a maximum current of 0.2A. Furthermore, its coefficient of leak resistance is 0.5% and the taper angle of its element is linear (B25 series). A Rheostat is a two-terminal variable resistor; it works by adjusting the resistance placed in series with a circuit without interrupting it. This type of device allows for the fine-tuning of the electrical current running through it, allowing an engineer to precisely control a motor’s speed, the volume of an audio amplifier, or any other device that requires precise adjustments of current. The KKA1021S28 Rheostat is a standard 3-terminal rheostat with a sealed die-cast body. It features an adjustable conductive wire element which allows the user to modify resistance by rotating the knob. The KKA1021S28 has a maximum power of 0.25W, a maximum voltage of 10V and a maximum current of 0.2A. Furthermore, its coefficient of leak resistance is 0.5%. KKA1021S28 Potentiometers and Rheostats offer a high level of performance and precision in measuring and controlling electrical current. Due to their ease of use and accurate current regulation, these devices are used in a variety of application fields such as electric appliances, telecommunications, automotive, industrial Automation, and general purpose Electronics.
