The **KTG-41-R** is a specific type of **Rotary Potentiometer**, typically used as a control component in industrial machinery, audio equipment, or consumer electronics. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. General Specifications The KTG-41-R is defined by its mechanical rotation and electrical resistance variance. | Feature | Description | | :--- | :--- | | **Component Type** | Rotary Potentiometer (Variable Resistor) | | **Resistance Range** | Commonly 1kΩ to 500kΩ (varies by sub-model) | | **Tolerance** | Usually ±20% | | **Power Rating** | Approximately 0.05W to 0.1W | | **Mounting Type** | Through-hole (PCB Mount) | --- ### 2. Key Electronic Parts & Construction The internal assembly of the KTG-41-R consists of several critical layers: * **Resistive Element:** A carbon film or cermet track that provides the resistance. * **Wiper:** A metal contact arm that slides across the resistive element to change the voltage/resistance ratio. * **Terminals:** Three pins (Input, Output/Wiper, and Ground). * **Housing:** A dust-proof casing (often plastic or metal) to protect the internal track from oxidation. --- ### 3. Pin Configuration Standard for the KTG-41 series, the device follows a 3-pin layout: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Fixed End (Low) | Usually connected to Ground (GND). | | **2** | Wiper (Center) | The output terminal that provides the variable voltage. | | **3** | Fixed End (High) | Connected to the Input Voltage (Vcc). | --- ### 4. Technical Characteristics * **Taper Type:** Usually **Type B (Linear)** or **Type A (Logarithmic)**. * *Linear:* Resistance changes proportionally to the angle of rotation. * *Logarithmic:* Used for audio volume control to match human hearing. * **Rotation Angle:** Typically 300° ± 5°. * **Rotational Life:** Rated for approximately 10,000 to 15,000 cycles. --- ### 5. Common Applications The KTG-41-R is frequently integrated into the following circuits: 1. **Volume Control:** Adjusting gain in amplifiers. 2. **Speed Regulation:** Controlling small DC motors via PWM signal modulation. 3. **Parameter Tuning:** Adjusting brightness in LED circuits or sensitivity in sensors.
