The **FRT-D6-R** is a specific model of a **Rotary Damper** manufactured by **Fuji Latex**. While it is often integrated into electronic assemblies, it is fundamentally a mechanical component used to control the motion of moving parts in electronic devices. Below is a detailed breakdown of its specifications and electronic applications. --- ### 1. Technical Specifications The FRT-D6-R is a small, gear-type rotary damper designed for smooth, controlled opening and closing mechanisms. | Feature | Specification | | :--- | :--- | | **Model** | FRT-D6-R | | **Type** | Rotary (Gear type) | | **Torque Range** | 0.40 ± 0.15 cN·m (at 20 RPM) | | **Rotation Direction** | Right (Clockwise) | | **Material** | Polycarbonate (Body), Silicone oil (Damping fluid) | | **Operating Temp** | 0 to 50°C | | **Gear Module** | 0.6 | --- ### 2. How it Works (Physics & Design) Although it does not contain wires or circuits, it is a critical "electromechanical support" part: * **Viscous Resistance:** The internal chamber is filled with high-viscosity silicone oil. As the gear rotates, the oil resists the movement, converting kinetic energy into heat. * **One-Way vs. Two-Way:** The "R" in the model name typically signifies the damping direction. This model provides resistance in the **Clockwise** direction, allowing for easier movement in the counter-clockwise direction (depending on the internal clutch mechanism). * **Integration:** It usually meshes with a plastic rack or a larger gear attached to an electronic housing or lid. --- ### 3. Applications in Electronics The FRT-D6-R is used to provide a "premium feel" and prevent mechanical shock in various electronic devices: 1. **CD/DVD/Blu-ray Players:** Controls the slow, smooth ejection of the disc tray. 2. **Smart Home Control Panels:** Used for flip-down screens or hidden button panels. 3. **Car Infotainment:** Manages the movement of retractable screens or glove boxes containing electronic ports. 4. **Audio Equipment:** Used in cassette deck doors or volume knobs that require a heavy, high-quality "damped" feel. --- ### 4. Comparison of FRT-D6 Variants | Model | Damping Direction | Typical Use Case | | :--- | :--- | :--- | | **FRT-D6-R** | Clockwise | Lids that open to the right or downward. | | **FRT-D6-L** | Counter-Clockwise | Lids that open to the left or upward. | | **FRT-D6-G** | Both Directions | General motion smoothing in both directions. |
