Rotary Potentiometers, Rheostats

The 39SA-1NB-103 poteniometer, often referred to as a "Rheostat" is a device commonly used to control the voltage in appliances and machinery. In basic terms, Rheostats are resistors that are variable in which resistance is adjusted with the help of a sliding lever to control the current. Compared to potentiometers, which are controlled by a shaft position, Rheostats are designed for continuous variation of resistance.

Application Field

Rheostats are often used in a variety of applications, including controlling speed of motors, controlling damping in vibration dampers, controlling the movement of solenoids, or adjusting the intensity of lighting. More sophisticated rheostats may be used for adjusting the brightness of displays, audio components, and other precision devices.

Working Principle

The 39SA-1NB-103 poteniometer is a variable resistor, and can also be called a "Rheostat". It has three terminals: the two end terminals, and the slider terminal. When the slider is connected to the main terminals, the circuit\'s resistance changes as the slider is moved across the resistor. When the slider is in between the two end terminals, it creates a bridge, dividing the resistor into two parts. This creates a change in resistance depending on how far the slider is from the end terminals.

In addition, Rheostats also have an internal mechanism, which may take the form of a coil of wire. This wire coil is positioned between the end terminals, and has a resistance that varies depending on the position of the slider. The presence of the internal mechanism allows for greater precision in controlling resistance.
