10K Rotary Potentiometer Round Shaft 3Pin Elcon
[Potentiometer] 10KΩ Rotary Potentiometer Round Shaft Elcon The 10KΩ Rotary Potentiometer Round Shaft Elcon is a reliable 3-pin variable resistor designed for adjusting electrical parameters such as voltage, current, brightness, motor speed, and other control functions in electronic circuits. By rotating the shaft, the resistance can be smoothly adjusted across its available range, making it suitable for a wide variety of DIY and electronic applications. With its compact 16mm body, 6mm round shaft, and through-hole mounting design, this potentiometer is easy to install on electronic PCBs and control panels. The linear resistance characteristics make it particularly suitable for applications such as LED brightness control, fan speed control, motor control, and general-purpose voltage adjustment. ⭐ Key Features 10KΩ resistance value 3-pin rotary potentiometer Linear potentiometer Smooth rotary adjustment 6mm round shaft Compact 16mm body diameter Through-hole mounting Suitable for PCB and electronic circuits Useful for voltage and current adjustment Suitable for LED, fan and motor control applications Elcon brand 📋 Technical Specifications Product Type: Rotary Potentiometer Brand: Elcon Resistance Value: 10KΩ Configuration: 3 Pin / Single Gang Tolerance: ±20% Shaft Type: Round Shaft Shaft Diameter: 6mm Shaft Length: 13mm Body Diameter / Width: 16mm Total Height: 30mm Mounting Type: Through Hole Operating Temperature: -40°C to +80°C Weight: Approx. 8g 🔧 Applications LED Brightness Control Fan Speed Control Motor Speed Control Voltage Adjustment Current Adjustment Power Supply Circuits Arduino Projects DIY Electronics Projects Audio & Electronic Circuits Electronic Prototyping 🛠️ How It Works A potentiometer is a variable resistor with three terminals. The two outer terminals are connected to the resistive track, while the center terminal acts as the wiper. Rotating the shaft changes the wiper position and therefore changes the resistance or output voltage in the circuit. 📦 Package Includes 1 × 10KΩ Rotary Potentiometer Round Shaft Elcon ⚠️ Note Product images are shown for illustrative purposes only and may differ slightly from the actual product. The 10KΩ value and ±20% tolerance are based on the supplied product specifications.
