Rotary Potentiometers, Rheostats, and RES5K0E Application Field and Working Principle

A potentiometer is a variable resistor. It is made of a resistive material between two terminals with a third connection called the wiper. By using the wiper, a current can be stepped up or down according to the voltage which is applied to the potentiometer. On the other hand, a rheostat is constructed from a single resistor with two terminals. To adjust the current which is going through the resistive material the wiper is used on both the potentiometer and rheostat.

RES5K0E, by Relak Industries, is a rotary potentiometer and rheostat all in one. This variable resistor has two terminals and a wiper which is in a semi–circular shape that can be rotated. This rotation varies the values of resistance between the two terminals of the potentiometer or rheostat. It is important to note that the output is changed as the wiper is rotated.

RES5K0E is an ideal device to be used in applications such as audio, power systems, telecom equipment, and instrumentation. Its features have been designed to meet the requirements of field applications. For example, its highly reliable ceramic element prevents against corrosion, its flat sections prevent against foreign particles entering, and it is designed with thin plates for better insulation. With a resistance range of up to 5k ohms, it is suitable for combining the linearity and ease of use of rotary potentiometers, and the smooth adjustment of rheostats.

The general working principle of RES5K0E can be explained as follows. When an electric current is applied to one of the terminals and the wiper is engaged, the other terminal will activate and the current flows through the resistive material. As the wiper is rotated, more or less electric current passes through the resistive material to the other terminal, depending on the wiper’s position. The amount of electric current which flows through the resistive material between the two terminals will increase and decrease depending on the position of the wiper.

In summary, RES5K0E is a rotary potentiometer and rheostat which can be used in a wide range of applications. It features a corrosion resistant ceramic element, highly reliable and stable performance, a resistance range of up to 5k ohms, and is designed for use with a flat section to reduce the possibility of foreign particles entering. Its working principle is based on the rotation of the wiper, which varies the amount of current which flows through the resistive material. RES5K0E is an ideal device for combining the linearity of rotary potentiometers and the smooth adjustment of rheostats.
