Slide potentiometers are adjustable resistors with a movable contact that slides to change its resistance value or electric voltage. They are used as manual variable resistors in a wide variety of applications, including audio volume control and light dimmers. In the most basic form, a slide potentiometer consists of a resistive element, a wiper contact, and a rotary or linear actuator.

The PTL30-19A1-103B2 is an example of a slide potentiometer. It is designed for enhanced performance and stability in volume control applications. It features a linear taper, a contact resistance of 1K ohm to 100K ohm range, and a terminal voltage rating of 1W to 30W. It has an operating temperature range of - 40°C to +135°C and a dielectric strength of 2000 VDC between terminals and between terminal and case.

The working principle behind a slide potentiometer is simple. When the control is moved, the wiper contact slides across the resistive element. The amount of resistance and voltage output is determined by the position of the wiper contact relative to the resistive element. When the wiper contact is moved closer to one end of the resistive element, the resistance increases, and so does the voltage output. Conversely, when the wiper contact is moved closer to the other end of the resistive element, the resistance decreases, and so does the voltage output.

The PTL30-19A1-103B2 is designed primarily for audio volume control applications. Its linear taper, terminal voltage rating, and contact resistance provide precise control and excellent signal linearity across the full range of operation. It is also well suited to audio mixing and equalizer applications, as well as light dimmers and other rotary or linear applications.

The PTL30-19A1-103B2 is RoHS compliant and comes in a variety of packaging options. It is also highly durable, with a contact life of up to 10 million operations. Its compact size and versatile design make it easy to install and configure in any application.

Slide potentiometers offer a reliable and cost-effective solution for manual control of electrical and electronic equipment. The PTL30-19A1-103B2 is a high-performance slide potentiometer designed specifically for audio volume control applications. Its robust construction and enhanced features make it ideal for a wide range of applications.
