Rotary Potentiometers and Rheostats are both devices used to control the flow of electrical current through a circuit. They have some similarities but also distinct differences. The 6657S-1-202 is an example of a Rotary Potentiometer and its application field and working principle will be discussed in this article.

A Rotary Potentiometer is a three-terminal device that acts as a variable resistor or voltage divider. It consists of a resistive element, a movable wiper arm connected to a rotating shaft and two fixed contacts. When the shaft is rotated, the wiper arm moves across the resistive element, changing the resistance between the two contacts and controlling the voltage or current in the circuit. Rotary Potentiometers are used in a wide variety of applications, from controlling sound volume in audio equipment to controlling motor speed in robotics.

The 6657S-1-202 is an example of a rotary potentiometer. It has a resistive element consisting of a carbon film with a rated resistance of 100 Kohm and a maximum power of 0.05W. It has a linearity of +-5% and a temperature coefficient of +-300ppm/degC. It has a mechanical angle of 300 degrees and a total rotation life of 10,000 cycles. The 6657S-1-202 can be used for various applications, such as volume, tone, balance and voltage control.

The working principle of the 6657S-1-202 is simple. When the shaft is rotated, the wiper arm moves across the resistive element. This changes the resistance between the two contacts, resulting in a change in voltage or current in the circuit. When the wiper arm is at one end, the resistance between the two contacts is at its lowest; when it moves to the other end, the resistance is at its highest. In between, the resistance varies depending on the exact position of the wiper arm.

The 6657S-1-202 can work in both AC and DC circuits. In an AC circuit, the voltage or current can be controlled simultaneously, while in a DC circuit, the voltage or current can be adjusted separately.

In conclusion, the 6657S-1-202 is an example of a rotary potentiometer, used to control the flow of electrical current in a circuit. Its application field is wide, ranging from audio equipment to robots. Its simple working principle is based on the varying resistance between two contacts depending on the position of the wiper arm. It can be used in both AC and DC circuits.
