Rotary Potentiometers, Rheostats

The P160KN-0QC20A1MEG is a rotary potentiometer/rheostat with multiple applications in electrical and mechanical engineering. It is primarily used in AC and DC circuits to provide precise control over voltage, current, or power by varying resistance.

Application Field

The potentiometer is used in a variety of electrical and mechanical applications, ranging from controlling the voltage and current in an electrical circuit to adjusting the speed of a motor or DC point-of-sale system. It can be used to precisely control the volume of a stereo, the intensity of lighting, or the speed of an engine. It is also used to control the voltage regulation in an amplifier, adjust the gain of a microphone preamp, or develop an adjustable light sensor.

Working Principle

The potentiometer works using three terminals, two ends, and a variable resistor. The two ends are the Inputs and the variable resistor is the Output. The potentiometer is usually connected in series with a source of electricity, such as a battery or generator. As the shaft of the potentiometer is moved, the Output changes its resistance, thereby controlling the voltage and current in the circuit.For AC applications, the voltage and current are directly proportional to the position of the knob or shaft of the potentiometer. That is, as the knob is turned clockwise, the voltage and current increase, and turning the knob counter-clockwise decreases the voltage and current. However, for DC circuits, the voltage and current vary inversely with the knob or shaft position.The potentiometer is an important instrument for electrical engineers, particularly for creating adjustable circuits, which can provide precise calibration and control over both AC and DC circuits. With its low cost and high precision, the potentiometer is a valuable and useful tool in many applications.
