Rotary potentiometers and rheostats are two types of mechanical electrical components with wide range of uses and applications. The main difference between them is the way they generate an electrical current in response to movement.

Rotary potentiometers, like the P160KN2-0QC20B100K model, are resistive components whose purpose is to vary theoutput signal of a system according to the angular position of a rotating shaft. In its simplest form, a rotary potentiometer consists of a track with two or more terminals. One of the terminals is connected to the central shaft while the other is connected to a moveable contact that slides along the track. As the shaft is rotated, the resistance between the terminals changes, thus modulating the output voltage of the system.

Rheostats, on the other hand, are two-terminal devices used to control current by changing resistance. In operation, the same principle as a potentiometer is applied: a sliding contact is placed between the two terminals, and when the contact is moved, the resistance between the two terminals changes, creating a variable resistance that controls the amount of current flowing through them. Rheostats, however, have a much higher current-handling capacity than potentiometers.

The P160KN2-0QC20B100K model is a rotary potentiometer designed to operate over a wide temperature range. It features a class B insulated core, rated for up to 0.6 Amp rated current and allowing for up to 10 turns of resistance adjustment. This makes it particularly suitable for a variety of applications requiring precise control of analog signals – from lighting and appliance control to medical device control and automation.

In summary, rotary potentiometers and rheostats are two types of useful mechanical electrical components with a wide range of uses and applications. Rotary potentiometers, like the P160KN2-0QC20B100K model, are resistive components whose purpose is to vary the output signal of a system according to the angular position of a shaft, while rheostats are two-terminal devices used to control current by changing resistance. Therefore, choosing the proper device for every particular application depends mainly on the type of output signal and the current needs.
