Rotary Potentiometers and Rheostats are two types of electronic components that have been used for many years. They are both used to regulate the flow of electricity in a circuit and their functions are similar, but they have different applications and working principles. In this article, we will discuss the EVJ-Y00F30D14 application field and working principle in detail.

EVJ-Y00F30D14 Application Field

The EVJ-Y00F30D14 is a rotary POT (potentiometer) which is a type of variable resistor. It can be used as a voltage divider to control the voltage and current in a circuit. It also can be used to adjust the audio volume, electric lamps, electric motors, and other electrical equipment, such as adjusting the speed of a DC motor. The EVJ-Y00F30D14 can control the flow of current by varying the resistance in the circuit.

The EVJ-Y00F30D14 is available in three sizes, ½, 1, and 2 inches. The larger the size, the higher the resistance and the more current it can carry. The EVJ-Y00F30D14 is also available in different resistance values ranging from 50 Ohms to 5 megohms.

EVJ-Y00F30D14 Working Principle

The EVJ-Y00F30D14 is a rotary potentiometer, which works on the principle of a variable resistor. It consists of three terminals namely the fixed terminal (A), adjustable terminal (B), and sense terminal (C). The adjustable terminal is connected to a conductive slider, which moves over a resistive track. As the slider movement is varied along the track, the resistance between terminals A and C will change correspondingly.

In order to obtain the accurate resistance from the device, the sense terminal (C) must be connected to ground. Doing this ensures that the resistance value is not affected by external factors, such as environmental temperature, pressure, or humidity. The overall resistance of the device is calculated by the ratio of the resistance between terminals A and C divided by the total track length (which is the distance between terminals A and B).

When the device is used as a voltage divider, the output voltage can be controlled by varying the position of the slider. The output voltage will vary linearly according to the slider position, and will be exactly equal to the input voltage multiplied by the ratio of the resistance between terminals A and C divided by the total track length.

Conclusion

In conclusion, the EVJ-Y00F30D14 is a rotary potentiometer, which is primarily used as a voltage divider and can be used to adjust the speed of electric motors, the volume of audio devices, and the brightness of electric lamps. It consists of three terminals and works on the principle of a variable resistor. When connected to ground, the output voltage can be adjusted by varying the position of the slider and will be equal to the input voltage multiplied by the ratio of the resistance divided by the total resistance of the device.
