Potentiometers

A potentiometer is a variable resistor used to adjust voltage or signal levels within a circuit by means of a sliding or rotating contact. Common in audio equipment, control panels, and hobbyist electronics, potentiometers come in a range of configurations to suit different applications.

RS Hong Kong stocks a wide range of potentiometers, including rotary, linear, and trimmer variants, with fast delivery across Hong Kong.

Types of Potentiometers

RS Hong Kong's potentiometer range covers rotary, linear, string, membrane, and trimmer variants to suit different control and adjustment needs.

Rotary Potentiometers

Rotary potentiometers are adjusted by turning a shaft or knob, commonly used for volume controls and other user-facing adjustment dials.

Linear (Slide) Potentiometers

Linear, or slide, potentiometers are adjusted by moving a slider along a straight track, often used in audio mixing equipment where precise, visual level control is helpful.

String Potentiometers

String potentiometers measure linear displacement using a retractable string connected to a rotary potentiometer, suited to applications requiring position sensing over longer distances.

Membrane Potentiometers

Membrane potentiometers use a thin, flexible resistive element, offering a low-profile design suited to space-constrained applications.

Linear Taper Potentiometers

Linear taper potentiometers change resistance at a constant rate as the control is adjusted, suited to applications requiring predictable, even adjustment.

Logarithmic (Audio) Taper

Logarithmic, or audio taper, potentiometers change resistance in a way that matches human perception of loudness, making them the standard choice for volume controls.

Trimmer Potentiometers

Trimmer potentiometers are small, typically adjusted with a screwdriver during calibration, and are designed for infrequent adjustment once a circuit has been set up.

Applications of Potentiometers

Potentiometers are used across a wide range of control and adjustment applications.

Industrial Control Panels & Instrumentation

Potentiometers are used in industrial control panels and instrumentation to provide manual adjustment of settings such as speed, sensitivity, or output levels.

Audio Equipment & Volume Control

Potentiometers are a core component in audio equipment, providing volume, tone, and balance control across amplifiers, mixers, and consumer electronics.

Electronics Hobbyist & Maker Projects

Hobbyists and makers use potentiometers in a wide range of DIY electronics projects, from simple control circuits to more complex sensor-based builds.
