Rotary Potentiometers, Rheostats

PDB12-H4251-104BF is a type of potentiometer which is used as a variable resistor and is mainly used for measuring voltage. The device is used to measure the voltage which varies over a very small range, from 0 to 100mA. It is a rotary device with four resistance contacts coupled to a circular shaft. This device is also referred to as a ‘rheostat’ and is used to control current, resistance or voltage. It is used in a variety of applications, including in audio and video equipment and medical devices, and has several advantages which have contributed to its popularity.

Application Field

The PDB12-H4251-104BF is mainly used in the audio and video industry. It is typically used for controlling the sound level and volume variations in CD players, radios, amplifiers, and speakers. It is also used in power supplies, in which it helps to set the desired output voltage. Additionally, it is used in the medical sector, including devices such as pacemakers, dialysis machines, and defibrillators. Finally, it is also used in a variety of circuit boards, where it is used to control amplitudes or to set levels for other components.

Working Principle

The PDB12-H4251-104BF works by using a rotary shaft that turns a central spindle, which itself is coupled to four resistances. As the spindle is rotated, the resistance values change and this in turn changes the voltage at the output. The output voltage can be measured by using either a DC or digital multimeter, depending on the application. The device can also be used to switch or control current or voltage on other devices. The amount of resistance that is provided by the device is preset and cannot be changed, however, it can be adjusted by changing the position of the rotary shaft.
