Rotary Potentiometers, Rheostats

A potentiometer is an adjustable resistor device that can control or measure voltage in a circuit. The 84C1D-E28-J15L is a rotary potentiometer. This device works by turning a shaft that is connected to the potentiometer wiper. As the dial is turned, the resistance of the resistor changes. By doing this, different levels of voltage can be controlled for any given amount of current passing through the component. Additionally, the device can also be used as a rheostat, which is a variable resistor used to control the amount of current passing through it.

Application Field

Rotary potentiometers, such as the 84C1D-E28-J15L, are commonly used in industrial and consumer applications. For example, they are used in the audio industry to adjust volume and tone, and in the automotive industry to control the temperature of a car’s air conditioning system. They are also commonly found in the heating and cooling industry, where they are used to regulate the temperature of refrigerators and freezers, as well as in the medical industry to help adjust the intensity of a patient’s dialysis machine.

Working Principle

The 84C1D-E28-J15L rotary potentiometer works on a nearly identical principle as its linear counterparts. It consists of a resistor, a dial, and wiper. As the dial is turned, the wiper moves along the track of the resistor, increasing or decreasing the resistance of the device. The device works on a simple principle: as the resistance of the device increases, so does the voltage, and as the resistance decreases, the voltage does too. This enables the device to be used to control the amount of voltage passing through it. Additionally, the device can also be used as a rheostat, which is a variable resistor used to control the amount of current passing through it.

Overall, the 84C1D-E28-J15L rotary potentiometer is an adjustable resistor device that is used to measure or control the voltage in a circuit. It is most commonly used in the audio, automotive, heating and cooling, and medical industries. It works by turning a dial that is connected to the potentiometer wiper, and as the dial is turned, the resistance of the resistor changes. By doing this, different levels of voltage can be controlled. Additionally, the device can also be used as a rheostat, which is a variable resistor used to control the amount of current passing through it.
