Rotary Potentiometers and rheostats are two of the most widely used technologies in a variety of applications. In this article, we will discuss the application field and working principle of PDB12-F4151-104BF, a rotary potentiometer/rheostat.

Rotary potentiometers, also called trimmers, are devices that enable fine adjustments or calibration of various electronic components. By physical turning of the potentiometer, its electrical resistance can be adjusted or adjusted by an external voltage or current. Generally, the resistance and adjustment range is expressed as ohm or ohm/volt. In contrast, rheostats are less adjustable than potentiometers, they are used to provide variable resistance to electric currents.

The PDB12-F4151-104BF is a hybrid rotary potentiometers/rheostats with a 0.25W to 0.5W power capacity and a resistance range of 0-200Kohms. This hybrid device is widely applied in a range of circuits such as radio and audio circuits, power supplies, control units, motion control systems, electrical household appliances and laboratory instruments. The PDB12-F4151-104BF is mainly composed of a fixed resistor, a wiper, a rotor, and a rotor shaft. When the rotor is turned, the contact between the wiper and the resistor generates an electrical signal.

The working principle of a PDB12-F4151-104BF rotary potentiometers/rheostat is simple yet efficient. The device comes with a rotary mechanism that consists of a fixed resistor, a wiper, a rotor and a rotor shaft. The rotor shaft extends through the resistor and engages to the wiper. As the resistance element is mainly made of carbon, the electrical signal generated by the contact between the resistor and wiper is sufficient to provide precise adjustments. Moreover, the characteristics of the device can be customized to meet specific requirements as it could come with a linear or logarithmic resistance adjustability.

In conclusion, PDB12-F4151-104BF is a hybrid rotary potentiometers/rheostats which is widely employed for a range of different applications. Its working principle is primarily based on its rotary mechanism which consists of a fixed resistor, wiper, rotor and rotor shaft. The device comes with a resistor that could be adjusted either linearly or logarithmically and provides reliable results on its electrical signal output. Besides, PDB12-F4151-104BF is extremely reliable and robust for use in large-scale as well as laboratory applications.
