Rotary Potentiometers and Rheostats, different appliances, have many things in common. The 6639S-1-102 is one of them, and it operates in both the two applications. It is a rotating device that consists of a resistive element, a wiper contact, and terminals. It has various applications and working principles.

The primary function of Rotary Potentiometers is to measure the voltage of a particular circuit. It is typically connected in a series circuit and used to control the amount of current passing through the circuit. The knob of the device is rotated to adjust the amount of current that passes through the series circuit. The voltage of the circuit is then measured from the output terminal.

In order to apply the 6639S-1-102 as a Rotary Potentiometer, the resistive element is connected in a series circuit, with the wiper contact connected to the output terminal. As the knob is rotated, the wiper contact moves along the resistive element, making contact with different points along it. This causes the current passing through the series circuit to increase or decrease, depending on where the wiper contact is. The output voltage can then be measured at the output terminal.

Rheostats are another application of the 6639S-1-102. Rheostats are used to control the amount of current in a circuit, but instead of being connected in series with the circuit, the device is connected in parallel with the circuit. When the knob is rotated, the resistance of the resistive element changes. This, in turn, affects the amount of current in the circuit.

To apply the 6639S-1-102 as a Rheostat, the resistive element is connected directly to the output terminal. The wiper contact is then connected to the circuit itself, either in parallel with the load or with the power source. The resistance of the resistive element is adjusted by rotating the knob, thus changing the amount of current in the circuit.

The 6639S-1-102 is an effective and versatile device. It can be used as both a Rotary Potentiometer and a Rheostat, and offers a convenient way to control the voltage and current in a circuit. The device is reliable and easy to use, making it a popular choice for many applications.
