Rotary Potentiometers, Rheostats

The P170N-FA10AR1K is a combination of a rotary potentiometer and rheostat, two device types commonly used for controlling electrical current. A potentiometer measures the amount of electrical resistance between two terminals and is typically used in applications such as analog-to-digital conversion and adjusting of volume or frequency. A rheostat, on the other hand, adjusts electrical current and can be used for switching and dimming power.

Both the potentiometer and rheostat portions of the P170N-FA10AR1K are rotary in design. The device is composed of a central post housing two connected, concentric coils of wire which rotate as the set screws are turned. The rheostat is connected to one of the rotating coils, while the potentiometer is connected to the other.

Applications

The P170N-FA10AR1K is commonly used in control systems, such as those in temperature or light regulation. The device is also used in audio equipment and amplifier circuits, where it is used to dim or adjust power output. In electronics testing applications, the device is used to measure resistance and adjust electrical current.

Working Principle

The potentiometer component of the P170N-FA10AR1K works on the principle of resistance between two terminals. The two concentric coils are connected to each other at the terminals, and the other end of each coil is connected to either the positive or negative terminal in the circuit depending on the application. As the rotating coils are adjusted with the set screws, they cause the resistance between the two terminals to change.

The rheostat component of the P170N-FA10AR1K also uses resistance to adjust current. The sliding contact of the rheostat is positioned in such a way that it moves across one of the two concentric coils, adjusting the resistance in the coil in order to control the amount of electrical current that passes through the circuit. Both the potentiometer and the rheostat are sensitive to the amount of current they are controlling.

The components of the P170N-FA10AR1K can be used together or independently, depending on the application. When used together, they offer a more efficient means of managing and controlling current than either component used alone.
