Rotary Potentiometers and Rheostats are both electronic components that have been used for many decades for a variety of applications. They can be divided into two categories based on structure and principle of operation.

Firstly, rotary potentiometers are known as variable resistor devices. The resistor is housed inside the component body which is basically a cylinder. The resistance is adjustable by rotating the shaft of the device. Electrical connections to the component are made with the help of three or more contacts. This type of potentiometer consists of two parts- a resistive element or track and a sliding contact which presses against the track. As the contact moves across the track, the resistance between two outer contacts or terminals varies and a voltage divider is formed. Changing the position of the sliding contact will thus result in the output signal changing accordingly.

The EVJ-Y91F03B24 rotary potentiometer is designed and manufactured specifically for applications involving circuit control and precision measurements. It has a 8 mm diameter, 24-position stepped shaft with an operating force of approximately 5N. It provides a higher resolution than regular potentiometers, with 8 positions per full revolution. The dynamic resistance is 3Kohm and offers good stability and long term reliability in humid and electrically noisy environments. It also features better linearity, less torque, and lower contact resistance.

Rheostats are also referred to as variable resistors. They are also an adjustable device, comprised of two terminals- one connected to a resistive element, the other connected to a moveable contact. The resistance between the terminals can be changed by moving the contact along the resistive element. The EVJ-Y91F03B24 rheostat offers a high-performance solution for applications such as sensor and LED dimming, fan speed control, motor control, and so on. The precision and shielding design of this component allow for smooth, precise control of electrical current with a very low contact resistance. It features an adjustable resistance range of 0.5Kohm to 8Kohm, and a total rotation angle of 270°. It is also protected from dust and water, making it suitable for use in harsh environments.

In conclusion, the EVJ-Y91F03B24 is a high-performance component for rotary potentiometers and rheostats. It is designed specifically to provide reliable performance and accuracy in circuit control and precision measurements, and offers a wide range of adjustable resistances for various applications. Thanks to its robust design, it can be installed and operated in humid and electrically noisy environments without any harm.
