Rotary Potentiometers, Rheostats

Rotary potentiometers and rheostats are the two most common types of variable resistors in the world. The PTV112-4420A-C104 is a rotary potentiometer that has been designed specifically for low-voltage applications. This type of variable resistor is used to control voltage in a circuit and is an important part of many electronic circuits.A rotary potentiometer is made up of three main components: a rotating contact disc, a fixed contact and a sliding contact. The rotating contact disc is connected to a resistive element, usually a spiral wound wire, which is what changes the resistance when the knob is moved. The fixed contact is connected to ground and the sliding contact is connected to the input voltage or signal source. When the knob is turned, the resistance between the fixed contact and the sliding contact is changed, allowing the current to flow at a different rate.The working principle of a PTV112-4420A-C104 is based on the change in resistance between the circuit’s input and output. It functions by controlling the current that flows between the two terminals by varying the resistance of the rotating contact. When the knob is rotated, the resistance changes and the output current will be altered. This type of variable potentiometer is ideal for low-voltage applications, such as those found in audio equipment, circuit control systems and instrumentation.The PTV112-4420A-C104 is a common component in many electronic applications, such as audio amplifiers, audio mixers, audio recording devices, electronic instruments and industrial control systems. In addition to its low-voltage capabilities, this type of potentiometer also offers good electrical and mechanical properties, making it a reliable solution for various types of applications.In addition to its use in electronics, the PTV112-4420A-C104 is also a popular choice for medical devices, automotive motors, and other appliances. This type of variable resistor can be used to adjust the speed of motors or other powered devices, regulate the temperature of heating and cooling systems, or even control the speed of a fan. By controlling the amount of current allowed to flow between two terminals, it can also be used as a voltage regulator.In summary, the PTV112-4420A-C104 is a rotary potentiometer that is designed specifically for low-voltage applications, such as audio equipment, circuit control systems and instrumentation. It functions by controlling the current that flows between the two terminals by varying the resistance of the rotating contact. This type of potentiometer offers excellent electrical and mechanical properties, making it a reliable and versatile solution for many applications.
