Rotary Potentiometers and Rheostats are popular innovations in the world of engineering. Potentiometers and rheostats are both variable resistors that are used to control the flow of electricity in a circuit. PTV142B40E120AB104 is a common product in the market that belongs to this class.

Application Field

PTV142B40E120AB104, a rotary potentiometer in a 4mm package, can be used in wide range of applications, including audio mixing consoles, electronic musical instruments, message switching systems, channel selection and so on. It can also be used in electronic chemical processes, measurement and control systems, power supplies and many other industrial and consumer products.

In addition, this potentiometer is also used in consumer applications, such as air conditioner, TV or refrigerator. It is designed to provide variable voltage outputs with excellent linearity over a wide range of temperature. Furthermore, this potentiometer can also be used as a linear control device for a wide range of digital and analog applications.

Working Principle

PTV142B40E120AB104 works by adjusting the resistance between two electrical contacts using a sliding contact. The resistor is usually a carbon track mounted on a ceramic core and connected to the two contacts. When one of the contacts (known as the wiper) is moved across the track, it changes the resistance that is seen between the two contacts, thereby changing the output voltage.

This process can be controlled by a dial or an external circuit which adjusts the voltage from the two contacts. The output voltage is then sent to the desired device. Depending on the application, the voltages can act as a signal to control the device, or to adjust the power dissipated to the device.

This potentiometer is a great device for controlling devices in a variety of applications, as it has a wide temperature range and provides accurate linear response. In addition, it also has an adjustable resistance range and is suitable for precision control.
