The REL125 is a rotary potentiometer, rheostat, which is a manual version of a variable resistor with an adjustable shaft or lever arm. It is similar to other rotary parts such as potentiometers, but its purpose is to deliberately alter the electrical resistance of an electronic circuit as its position is changed. It has a wide range of uses in many applications, where the precise adjustment of an electrical resistance is desired. It is also sometimes referred to as a “pot” or “potentiometer”.

The working principle of a REL125 is simple. It is a three-terminal device with two fixed terminals and one adjustable terminal. The adjustable terminal is connected to a shaft or lever arm, which when turned, moves the terminal and changes the electrical resistance between the two fixed terminals. This allows for the adjustable electrical resistance between the two fixed terminals, which can be adjusted to an infinite number of settings depending on the mechanical design of the device.

The REL125 is used in a wide range of applications, such as controlling the wattage of a heating element in an electric frying pan, adjusting the wave shape of a signal voltage on an oscilloscope, controlling the speed of a motor in an industrial application, or adjusting the brightness of a light bulb. It is particularly useful in applications where an adjustable parameter needs to be precisely controlled over a wide range. It is also used in radio transmitters, allowing signals to be tuned in frequency or amplitude, and in audio systems to adjust treble and bass settings.

In addition to its use in electronics, the REL125 can also be used as a rheostat, or a manually operated device used to adjust the current or voltage in circuits. Rheostats can be used to control machine tool motors, speed winders, and hoists, as well as many other industrial machine applications. The REL125 is preferable to other rheostat designs in these applications due to its superior durability and accuracy.

The REL125 is an invaluable tool in the electronics industry, able to provide precise control in a wide range of applications. Its versatility and durability make it an ideal choice for those who need precise and reliable adjustment of electrical resistance in their projects. Whether you are an engineer, hobbyist or industrial operator, you can rely on the REL125 to deliver consistent control in all your projects.
