Rotary Potentiometers & Rheostats

In many applications, such as DC motors and dimmers, rheostats are essential for regulating the current and voltage in an electrical system. Potentiometers and rheostats offer an array of useful features when it comes to controlling these devices. They are polarized, which means they can detect the direction of the current or voltage that is flowing through them.

The PTD902-1220F-A204 is a rotary potentiometer and rheostat that entered the market in June 2017 and offers a range of features, including a large operating range, low temperature coefficient, and superior overall operating life. It is designed specifically for 30 mA of current or voltage and is suitable for use in motor control circuits.

Application Field

The PTD902-1220F-A204 is a high-quality rotary potentiometer and rheostat that can be used in industrial applications to regulate current and voltage in DC motors and dimmers. Examples of industries in which the device is applicable include aerospace, automotive, consumer electronics, medical, and industrial.

Working Principle

The PTD902-1220F-A204 works by adjusting the flow of current or voltage through an internal resistor. When the knob is rotated, the variable resistor element changes its resistance, allowing for greater or lesser amounts of current or voltage. This provides precise control over the power being delivered in an electrical system, allowing users to precisely adjust the power to their desired level.

It is important to note that this potentiometer and rheostat only works in one direction, which is why it is important to be aware of the direction of current or voltage that needs to be controlled before use. The PTD902-1220F-A204 is designed specifically to handle 30 mA, so it should not be used for higher current levels.

The device comes with a variety of options to choose from, such as metal shafts, switches, and nuts. It is also temperature-resistant (up to 125°C) and waterproof, making it suitable for use in a wide variety of applications. Additionally, its superior operating life means that it can last up to 100 times longer than other similar devices.

In summary, the PTD902-1220F-A204 is a reliable rotary potentiometer and rheostat designed for 30 mA current or voltage that can be used in industrial applications to regulate current and voltage in DC motors and dimmers. It is temperature resistant and features superior operating life for a long service life. It is very easy to use and provides a reliable, precise level of control.
