The **FRT-E2-R/Q** refers to a high-performance, compact rotary damper manufactured by **Fuji Latex**. These components are widely used in the electronics and automotive industries to provide smooth, controlled opening and closing motions for lids, drawers, and covers. --- ### 1. Technical Specifications The "R" and "Q" designations typically refer to the gear type or the torque directionality. | Feature | Specification Details | | :--- | :--- | | **Type** | Rotary Vane Damper | | **Torque Range** | Typically 0.20 to 0.50 N·m (Newton meters) | | **Rotation Angle** | 110° (Standard for E2 series) | | **Operating Temp** | -10°C to 60°C | | **Housing Material** | Polycarbonate (PC) or PBT Plastic | | **Damping Oil** | Silicone Oil | --- ### 2. Internal Electronic/Mechanical Components While the device is passive (does not require electricity to operate), its design is critical for electronic enclosures: * **Rotor:** The central moving part that connects to the hinge. * **Stator/Body:** The outer shell that stays fixed to the chassis. * **Silicone Fluid:** A high-viscosity fluid that provides resistance. As the rotor turns, the fluid is forced through narrow gaps, converting kinetic energy into heat. * **One-way Clutch (Optional):** Some versions (like those indicated by specific suffixes) allow free movement in one direction while providing damping in the opposite direction. --- ### 3. Application in Electronic Devices These dampers are integrated into the following electronic hardware: 1. **Consumer Electronics:** CD/DVD/Blu-ray player trays, high-end cassette decks, and turntable lids. 2. **Automotive Electronics:** Center console lids, glove boxes, and retractable GPS screens. 3. **Office Equipment:** Printer scanner lids and paper tray slow-release mechanisms. --- ### 4. Part Number Breakdown The nomenclature usually follows this logic: | Prefix | Series | Direction/Torque | Gear Code | | :--- | :--- | :--- | :--- | | **FRT** | **E2** | **R** (Clockwise) | **Q** (Specific Gear Profile) | | Fuji Rotary | Compact Size | Or L (Counter-Clockwise) | Pitch/Module of the gear | ---
