### FRT-6D-R: Electronic Parts and Specifications The **FRT-6D-R** is a high-precision, miniature **rotary damper** manufactured by **Fuji Latex**. These components are widely used in electronics and mechanical assemblies to provide controlled, smooth motion (soft-closing mechanisms). --- ### 1. Key Technical Specifications The "6D" designation typically refers to the torque rating and internal resistance characteristics. | Feature | Specification | | :--- | :--- | | **Part Number** | FRT-6D-R | | **Rotation Direction** | Clockwise (CW) | | **Rated Torque** | ~6.0 mN·m (milli-Newton meters) | | **Maximum Rotation Speed** | 50 RPM | | **Operating Temperature** | -10°C to 50°C | | **Material** | Polycarbonate (Body), Stainless Steel (Shaft) | --- ### 2. Internal Components & Materials While the device is mechanical in function, its "electronic parts" context usually refers to its integration into electronic hardware. The assembly consists of: * **Rotor & Stator:** The internal moving part (rotor) and the fixed housing (stator). * **Silicone Oil:** A high-viscosity fluid that provides the damping force through shear resistance. * **O-Ring Seals:** High-quality rubber seals (usually NBR) that prevent the silicone oil from leaking into sensitive electronic circuitry. * **Gear/Shaft:** The interface that connects to the door, lid, or tray of the electronic device. --- ### 3. Application in Electronics The FRT-6D-R is commonly found in the following electronic assemblies: 1. **Optical Disc Drives (ODD):** Ensures the CD/DVD tray opens smoothly rather than ejecting violently. 2. **Control Panels:** Used in flip-down covers for AV receivers or printers. 3. **Smart Home Devices:** Soft-close lids for motorized trash cans or automated kitchen appliances. 4. **Automotive Interior Electronics:** Slow-release glove boxes and center console lids. --- ### 4. Comparison: R vs. L Models It is vital to distinguish the rotation direction when selecting these parts for a PCB or mechanical assembly: | Model | Damping Direction | | :--- | :--- | | **FRT-6D-R** | **Clockwise** (Resistance is applied when turning CW) | | **FRT-6D-L** | **Counter-Clockwise** (Resistance is applied when turning CCW) | | **FRT-6D-W** | **Bi-directional** (Resistance in both directions) | ---
