4.7K Ohm Linear Rotary Potentiometer (4.7KΩ Adjustable Variable Resistor)

The 4.7K Ohm Linear Rotary Potentiometer (4.7KΩ Adjustable Variable Resistor) is a high-quality variable resistor designed to provide smooth, accurate, and reliable manual adjustment of voltage, current, and signal levels in a wide variety of electronic circuits. With a maximum resistance of 4.7K Ohms (4,700Ω) and a linear taper, this potentiometer delivers a uniform change in resistance throughout the entire rotation of the shaft, making it ideal for applications requiring precise and predictable control.

The potentiometer consists of a durable resistive track, a rotating metal shaft, and a movable wiper that slides across the resistive element as the shaft is turned. This movement changes the resistance between the terminals or adjusts the output voltage when used as a voltage divider. Its linear response ensures that the resistance changes proportionally with the shaft position, making it suitable for calibration, analog signal adjustment, voltage regulation, sensor interfacing, and electronic control circuits.

Manufactured using premium-quality resistive materials and corrosion-resistant metal contacts, the 4.7K Ohm Linear Rotary Potentiometer provides excellent electrical stability, smooth rotation, low contact noise, and a long mechanical lifespan. The robust metal shaft is compatible with standard control knobs, while the threaded bushing enables secure panel mounting for reliable installation in electronic equipment, control panels, and custom enclosures.

The 4.7K Ohm Linear Rotary Potentiometer is widely used in Arduino, ESP32, ESP8266, Raspberry Pi, STM32, audio equipment, analog control circuits, industrial automation, robotics, embedded systems, laboratory instruments, power supplies, educational electronics, DIY projects, and electronic repair applications. It is commonly used for volume control, LED brightness adjustment, motor speed control, sensor calibration, reference voltage generation, signal conditioning, and analog input applications.

Its compact size, simple three-terminal configuration, and dependable performance make it an essential component for engineers, technicians, students, makers, and electronics enthusiasts who require accurate manual control in analog and embedded electronic systems.

Working Principle

The 4.7K Ohm Linear Rotary Potentiometer operates by changing resistance through the rotation of its shaft.

Inside the potentiometer, a resistive element is connected between the two outer terminals, while the center terminal is connected to a movable contact called the wiper. As the shaft is rotated, the wiper moves along the resistive track, changing the resistance between the center terminal and each outer terminal.

When connected as a voltage divider, the potentiometer provides an adjustable output voltage proportional to the shaft position. When used as a variable resistor (rheostat), it controls current flow by changing the resistance in the circuit.

Because it features a linear taper, the resistance changes evenly across the full range of rotation, making it ideal for precision adjustment, calibration, and control applications.
