Description

B5K Linear Rotary Potentiometer: Precision Analog Control

Technical Specifications of Potentiometer (Variable resistor) 5K

• Resistance Value: Fixed maximum of 5K ohms with a smooth linear taper (Type B).

• Power Rating: Rated at 0.5 Watt (1/2W) for low-power signal and control applications.

• Shaft Design: Features a 6mm knurled shaft for easy knob attachment and manual rotation.

• Dimensions: Shaft length of 13mm and a compact 16mm base diameter for tight PCB layouts.

• Mounting: Standard 7.5mm mounting hole required for secure panel or chassis installation.

• Material: Durable metal construction with high-quality electronic internal contact parts.

• Adjustment Type: Top adjustment rotary lever providing a full 300-degree rotational travel range.

• Usage: This Potentiometer (Variable resistor) 5K is breadboard-friendly and perfect for prototyping.

Usage and Calibration in Analog Circuits

• First, connect the outer two pins to your VCC and Ground power rails.

• Next, link the middle wiper pin to your microcontroller’s analog input (ADC) pin.

• Then, rotate the knurled shaft to vary the output voltage between 0 and VCC.

• Afterward, utilize the component to adjust audio volume or LED brightness levels.

• Consequently, the Potentiometer (Variable resistor) 5K acts as a reliable voltage divider.

• Finally, secure the base to your control panel using the included nut and washer.

Advantages and Disadvantages of Potentiometer (Variable resistor) 5K

• Pros: Linear taper ensures a predictable, proportional change in resistance throughout the entire rotation.

• Furthermore, the knurled shaft supports various plastic or metal knobs for an attractive finish.

• Cons: Mechanical friction causes the internal carbon track to wear down after thousands of cycles.

• Additionally, the open-frame design can accumulate dust, potentially causing signal noise over time.

Precautions and Board Handling

• Warning: Do not exceed the 0.5W power rating to prevent burning the internal resistive track.

• Avoid applying excessive force to the shaft to protect the internal mechanical stop mechanism.

• Ensure the pins are not bent excessively during insertion into a breadboard or PCB.

What is Included in the Package

• 1x Potentiometer (Variable resistor) 5K (B5K Linear Taper).
