Its D-type shaft provides a secure grip for a compatible knob, while the included nut allows the potentiometer to be securely fixed to a panel or enclosure. The compact 16mm body makes it suitable for PCB and general-purpose electronic applications. ⭐ Key Features 10KΩ total resistance B10K linear taper 3-pin configuration D-type shaft Compact 16mm potentiometer Includes fixing nut Suitable for PCB mounting Can be used as a variable resistor Can be used as a variable voltage divider Suitable for tone and electronic control applications Breadboard compatible according to the supplied specifications 📋 Technical Specifications Product Type: Rotary Potentiometer Brand: Elcon Potentiometer Value: B10K / 10KΩ Taper: Linear Number of Pins: 3 Shaft Type: D-Type Shaft Diameter: 4mm Shaft Length: 8–10mm Pins Pitch: 4.4mm Dimensions: 25mm × 16mm × 16mm Nut Inner Diameter: 6mm Nut Outer Diameter: 10mm Mounting: PCB / Panel Mount Breadboard Compatible: Yes 🔌 Pin Function Outer Pin 1: Resistive track terminal Center Pin: Wiper / Variable output Outer Pin 3: Resistive track terminal The resistance between the two outer pins remains approximately 10KΩ, while the resistance between the center pin and either outer pin changes as the shaft is rotated. 🔧 Applications Tone Control Audio Circuits Volume & Signal Adjustment LED Brightness Control Motor Speed Control Voltage Adjustment Variable Resistor Applications Arduino Projects DIY Electronics Projects PCB Prototyping General Electronic Control Circuits 🛠️ How It Works When used as a potentiometer, the center pin acts as the adjustable wiper and provides a variable output across the rotation range. When used as a variable resistor, the wiper can be connected with one of the outer terminals to obtain an adjustable resistance. 📦 Package Includes 1 × Elcon B10K 10KΩ 3-Pin Rotary Potentiometer 1 × Fixing Nut ⚠️ Note Product images are for illustrative purposes only and may differ slightly from the actual product. The supplied specifications state a shaft length of 8–10mm; please verify the exact dimensions against the actual product batch before installation.
10K Ohm 16mm Linear Taper 6-Pin Dual Gang Rotary Potentiometer
[Potentiometer] 16mm 10KΩ 6-Pin Dual-Gang Rotary Potentiometer The 16mm 10KΩ 6-Pin Rotary Potentiometer is a compact and versatile dual-gang rotary potentiometer designed to control two separate electrical channels simultaneously using a single rotary shaft. With 6 pins in total, each potentiometer section has 3 terminals, making it suitable for stereo audio control, dual-channel signal adjustment, amplifier circuits, tone control, and various DIY electronics applications. By rotating the shaft, the resistance of each potentiometer section can be adjusted smoothly. The dual-gang construction allows both channels to be controlled together, making this potentiometer particularly useful for stereo volume control and other applications requiring synchronized adjustment. ⭐ Key Features 10KΩ resistance value 16mm body diameter 6-pin dual-gang configuration 3 pins per potentiometer section Single rotary shaft controls both gangs Smooth and reliable rotary operation Compact design Suitable for PCB and panel mounting Ideal for stereo and dual-channel applications Suitable for audio and general electronic circuits Compatible with suitable potentiometer knobs 📋 Technical Specifications Product Type: Rotary Potentiometer Resistance Value: 10KΩ Body Diameter: 16mm Configuration: Dual Gang Number of Pins: 6 Pins per Gang: 3 Operation: Single Turn Rotary Shaft Length: 9mm Total Potentiometer Height: 27mm Mounting Type: PCB / Panel Mount Application: Variable Resistance / Voltage Control 🔌 Pin Configuration The potentiometer has 6 pins in total, divided into two independent 3-pin sections: Pins 1, 2 & 3: First potentiometer section Pins 4, 5 & 6: Second potentiometer section Each section consists of two resistive-track terminals and one center wiper terminal. Rotating the shaft moves the wiper and changes the resistance or output voltage. 🔧 Applications Stereo Audio Volume Control Audio Amplifiers Tone Control Circuits Pre-Amplifier Circuits Dual-Channel Signal Adjustment LED Brightness Control Motor Speed Control Power Supply Adjustment 555 Timer Circuits Arduino Projects ESP32 Projects DIY Electronics Projects Audio Equipment Electronic Prototyping 🛠️ How to Use The two outer terminals of each potentiometer section can be connected across the required voltage or signal path, while the center terminal works as the adjustable wiper output. In stereo audio applications, one gang can be used for the left channel and the other gang for the right channel, allowing both channels to be adjusted simultaneously. 📦 Package Includes 1 × 16mm 10KΩ 6-Pin Dual-Gang Rotary Potentiometer ⚠️ Precautions Check the pin configuration before connecting the potentiometer. Do not exceed the electrical limits of the connected circuit. Ensure correct wiring when using both gangs for stereo applications. Use a suitable knob compatible with the shaft. The exact taper and shaft shape may vary depending on the product variant.
