Slide Potentiometers

PDV30-21P-103A application field and working principle

A slide potentiometer is a component used to control electrical signals. It consist of a plunger or a sliding element that slides over an electrical resistive strip. Slide potentiometers are widely used in various types of applications. They can be used to control the input levels of voltage, trigger motors, and set levels for devices such as amplifiers.

The PDV30-21P-103A is a simple slide potentiometer that is designed for basic applications. It is a single-pole, single-throw (SPST) device, meaning it can open or close an electrical circuit when it slides over the resistive strip. It uses a 3 mm (0.12 inch) thick resistive strip and can be adjusted using a 5 mm (0.20 inch) long slider on the top. The resistive strip is sealed inside the component so it is protected from external environmental conditions.

The operation of the PDV30-21P-103A is very simple. As the slider is moved along the resistive strip, the contacts of the device open or close depending on the position of the slider. This creates an electrical current that can be directly connected or routed to other electrical devices. The resistance of the strip can be adjusted so that the electrical current can be tuned or regulated as desired.

The PDV30-21P-103A is mainly used in light dimmer applications. These applications require a component that can accurately and consistently adjust the power or current supplied to the light source. The slide potentiometer provides a simple and convenient way to do this. The resistive strip can be adjusted to achieve the desired power levels and can be further adjusted for optimal performance.

The PDV30-21P-103A can also be used in applications such as volume control, speed control, and vibration control. It is a reliable and cost-effective solution for many different types of basic electronics applications. It is also easy to install and use, making it a popular choice for basic applications.

The PDV30-21P-103A is a simple and versatile slide potentiometer that can be used in many applications, allowing users to conveniently and consistently regulate the power or current supplied to electrical devices. With its small size, low cost, and easy installation, the PDV30-21P-103A is an ideal solution for simple applications requiring precise control of electrical signals.
