A rotary potentiometer, or ‘pot’ for short, is a type of variable resistor that consists of a resistor with a rotator attached to its head. The resistance between the two ends of the resistor varies when the rotator is rotated. Likewise, a variable rheostat is also a type of variable resistor, but instead of having one end connected to one of two fixed posts, it has a slider or rotor that moves along a resistance track, thereby varying the resistance between the two ends of the resistor. In either case, the exact resistance will depend on how far the rotator or slider has been rotated, making it a good choice for many given applications.The EVJ-C20F02D14 is a rotary potentiometer from ALPS Electric. It has a resistance range between 0 and 20k ohms with a power rating of 0.2 watts. It is also a non-shorting type, meaning that the resistance track won\'t become completely shorted when turned to its lowest or highest settings. The EVJ-C20F02D14 is available in a variety of mounting styles, including through-hole, SMD, and even miniature versions, making them well-suited for both through-hole and surface mount applications.The working principle of the EVJ-C20F02D14 is fairly straightforward. When the resistance track is turned, the resistance between the two ends of the resistor will change in proportion to the amount that it is turned. For instance, if the rotator is turned half way, the resistance between the two ends of the resistor will be roughly 10k ohms. As for how the resistance changes as the rotator is turned, it will usually follow a logarithmic curve, meaning that it will have a higher resistance when turned to the lower settings and a lower resistance when turned to the higher settings. However, this can be adjusted via the potentiometer\'s trim tab if necessary.The EVJ-C20F02D14 is a very versatile device that can be utilized in a number of different applications. It is commonly used in audio and video equipment, such as TVs and stereo systems, for adjusting the volume or tuning in to a specific channel. It is also frequently used as a speed or brightness controller in machines such as washing machines and electric fans. In addition, it can be used to adjust the temperature of a device, such as an air conditioner or oven, by controlling the voltage to the device in response to the resistance from the potentiometer. And lastly, they can also be used to provide feedback for sensors and other instruments.In conclusion, the EVJ-C20F02D14 is a versatile and reliable rotary potentiometer that can be used in a wide variety of applications. It is easy to install and adjust, and its non-shorting feature ensures that it won\'t be damaged if turned too far. The resistance track follows a logarithmic curve, making it simple to adjust the resistance between two points, and the trim tab allows for further fine-tuning if needed. This makes the EVJ-C20F02D14 a great choice for many given applications, ranging from audio and video equipment to adjustable speed and temperature controls.
