Rotary Potentiometers, Rheostats

PTV111-1415A-A3104 Application Field and Working Principle

Rotary potentiometers, also known as rotary rheostats, are electromechanical components which are used to measure, control, and adjust the electrical voltage, current and power of various electrical devices. The PTV111-1415A-A3104 is a 10 turn, single-gang potentiometer, designed for use in automated tests in industrial and commercial applications.

Application Field

PTV111-1415A-A3104 is mainly used in industrial measurement and control, such as in feedback control of current, voltage regulation, pressure, flow, temperature and other display applications, as well as in high precision laboratory equipments like power meters, oscilloscopes, etc. It is also used in some consumer products like remote controls, cameras, medical devices, and so on.

Working Principle

The PTV111-1415A-A3104 is based on a resistive element which is divided into ten sections. The movable element of the unit, the wiper, is extended or retracted to select one of the sections, thereby changing the resistance of the unit. This change in resistance will cause a corresponding change in voltage or current, which is the output of the unit. The turning direction of the rotary control sets the direction of the output voltage, either clockwise or counterclockwise. The potentiometer is often referred to as a "pot" for short.

The resistance of the component can be easily changed by manually rotating the knob of the potentiometer. This resistance control can be used to adjust the output of a device, such as a motor or amplifier, by changing the voltages, currents, and powers of the signal. The output voltage or current is proportional to the rotation angle of the knob.

The PTV111-1415A-A3104 is designed to provide the highest quality in long-term stability, and features a dust proof and moisture proof plastic enclosure, along with a robust construction made of stainless steel and an anti-corrosion coating. Additionally, its terminals have a special two-layer spring design which ensure a tight connection and reduce the risk of short-circuiting.

Conclusion

The PTV111-1415A-A3104 rotary potentiometer is a specialized electromechanical device designed for use in a wide variety of industrial and commercial applications. It is based on resistive elements divided into ten sections, and its output is proportional to the angle of rotation of the component\'s knob. This device is designed to provide high-quality performance and long-term stability, thanks to its robust construction, dust- and moisture-resistant plastic enclosure, and two-layer spring design.
