Rotary Potentiometers and Rheostats are electromechanical sensing devices used to measure electric current. The PDA241-HRT02-105B0 is a model in this family that is widely used in a variety of industrial and commercial applications.

Rotary Potentiometers have a long resistance element, typically made from a carbon composition, or a variable resistor, that is mechanically rotated by a shaft. As the device is rotated, a small wiper or arm contacts the rotating element, and this contact determines the voltage output from the device. In essence, what is happening is the wiper is tapping into the resistance element with different resistances as the shaft is turned.

Rheostats operate similarly to rotary potentiometers, but the resistance element is shorter. As the shaft is rotated, the wiper taps into the resistance element with different resistances, which is then tapped into the circuit, allowing the device to quickly adjust the current to the desired level. Rheostats are very useful when multiple devices need to be adjusted simultaneously.

The PDA241-HRT02-105B0 is a model of a rotary potentiometer or rheostat. It uses a plastic-encased contact element that is capable of handling up to 0.25 watts of power, and has a range of resistance settings from 50 ohms to 5K ohms. The maximum operating temperature of this device is 85 degrees Celsius, and its resistance tolerance is ±5%.

The PDA241-HRT02-105B0 can be used in a variety of applications, from motor controllers to voltage regulators. It is typically used in applications where current must be adjusted quickly and accurately. For example, it is commonly used as the speed control for electric motors or as a voltage stabilizer. Additionally, it can be used in more advanced applications, such as an adjustable current source for a bridge rectifier.

When the PDA241-HRT02-105B0 is used in an electric motor controller, its resistance is varied with a knob that is wired to the device itself. This knob varies the voltage or current output of the device, allowing the motor to be adjusted to a desired speed. In a voltage regulator, the device monitors the amount of voltage being supplied to a device and allows the voltage to be adjusted as needed. This device is also used in adjustable current sources for bridge rectifiers, which use the rheostat to adjust the maximum current through the bridge.

The PDA241-HRT02-105B0 is an extremely reliable and accurate device for any application requiring precise voltage and current adjustment. With its ±5% tolerance rating, this device is capable of providing reliable and consistent performance over a wide range of applications. The device is also extremely durable and can withstand extreme temperatures and vibration, making it an ideal choice for long-term use.
