Potentiometers
Potentiometers are variable resistors used to precisely control resistance, voltage, or current within an electrical circuit. RSP Supply carries a full line of potentiometers, including rotary and linear styles, designed for accurate control and calibration in electronic circuits, motion control systems, and instrumentation. These devices are commonly used where stable, repeatable adjustment of electrical parameters is required.
Potentiometers are available with a variety of resistive element materials to suit different performance and durability needs. Cermet potentiometers offer excellent stability and precision for calibration and measurement applications. Chromium-plated metal and other metal film designs provide durability and consistent performance in industrial environments, while plastic and conductive plastic potentiometers deliver smooth operation and long service life in control and adjustment applications. Most potentiometers supplied are non-illuminated, making them ideal for internal control circuits and applications where visual indicators are not required.
Available in single-turn and multi-turn configurations, potentiometers function as adjustable voltage dividers using a fixed resistive element and a movable wiper. Linear taper potentiometers provide proportional resistance change relative to shaft position, while logarithmic taper potentiometers adjust resistance non-linearly and are commonly used in audio and signal control applications. These options make potentiometers versatile components across both user-operated and embedded electronic systems.
FAQs
Q: What is a potentiometer?
A potentiometer is a variable resistor used to adjust resistance, voltage, or current within a circuit by moving a sliding or rotating contact across a resistive element.
Q: What types of potentiometers are available?
Common types include rotary potentiometers, linear potentiometers, single-turn potentiometers, and multi-turn potentiometers, each suited to different control and adjustment needs.
Q: What materials are used in potentiometer resistive elements?
Resistive elements are typically made from materials such as carbon composition or conductive plastic, depending on performance and durability requirements.
Q: What resistance values are available for potentiometers?
Potentiometers are available in a wide range of resistance values, from a few ohms to several megaohms, depending on the application.
Q: What is the difference between linear and logarithmic taper potentiometers?
Linear taper potentiometers change resistance proportionally with movement, while logarithmic taper potentiometers change resistance non-linearly and are commonly used in audio applications.
