Rotary potentiometers and rheostats are similar in many ways but are also distinct in their functions. Both are resistance devices and components used in electronic circuits, allowing the resistance of a circuit to be adjusted. Rotary potentiometers and rheostats are used for a range of applications, including industrial and home automation, sound systems, lighting, motors, and many more.

381L2500 Application Field and Working Principle

The 381L2500 rotary potentiometer is an adjustable resistor used in electronic applications. With this device, the resistance in a circuit can be adjusted without changing the connections. Commonly used for volume control in sound systems, this device can be used to control mains and LED lighting, motors, and many more.

The 381L2500 consists of three main parts; the shaft, the housing, and the resistance track. The shaft is the mechanism which rotates, allowing the user to adjust the resistance in a circuit. The housing is the enclosure around the device, containing the contacts which attach to the circuit. The resistance track consists of two resistive surfaces which the shaft contacts when rotated. As the shaft moves, the position is continuously changing and altering the circuit’s resistance.

The 381L2500 can be adjusted from approximately 7W to 23W. This makes it ideal for a range of applications, such as controlling volume levels and LED colours in sound systems and lighting solutions. It is designed to be robust and reliable, and has an IP67 rating making it waterproof and dustproof.

The 381L2500 is also suitable for motor control. By adjusting the resistance, the speed of the motor can be controlled. This is a simple and cost-effective solution for controlling a wide range of motors, from fans and pumps to door locks and automated lifts.

Finally, the 381L2500 has many other uses, such as power regulation, dimming of LED lighting, and automated air-conditioning control. This broad range of applications makes the 381L2500 the ideal device for a variety of electronic solutions.
