The **FRT-62-R** refers to a specific series of **Rotary Damper** components, typically manufactured by companies like Fuji Latex. These are mechanical-electronic integration parts used to control the speed and smoothness of moving lids, drawers, or covers. --- ## 1. Technical Specifications The "FRT" series generally follows a standardized naming convention defining its torque and physical characteristics. | Feature | Specification | | :--- | :--- | | **Type** | Rotary Vane Damper | | **Torque Range** | Typically 0.2 N·m to 1.0 N·m (varies by sub-model) | | **Rotation Angle** | 360 degrees (Continuous) | | **Operating Temp** | -10°C to 60°C | | **Housing Material** | Polycarbonate (PC) or POM | | **Damping Fluid** | Silicone Oil | --- ## 2. Key Internal Components While it looks like a simple plastic gear, the FRT-62-R relies on fluid dynamics and material science to function: 1. **The Rotor (Gear):** The external part that interfaces with the application (e.g., a toilet seat hinge or a printer tray). 2. **Silicone Oil:** A high-viscosity fluid trapped between the rotor and the stator. As the rotor turns, the oil provides resistance (damping). 3. **O-Ring Seals:** Critical for preventing leakage of the silicone oil, ensuring the part remains maintenance-free for its lifecycle. 4. **Housing:** The outer casing that holds the internal pressure and provides mounting points. --- ## 3. Working Principle The FRT-62-R operates on the principle of **viscous shear**. * When a force is applied to the gear, the internal rotor moves through the silicone oil. * The oil creates a resistive force proportional to the speed of rotation. * **Result:** The faster you try to move the object, the more resistance the damper provides, resulting in a "soft-close" or controlled motion effect. --- ## 4. Typical Applications These components are found in high-end consumer electronics and automotive interiors: * **Office Equipment:** Slow-opening scanner lids or printer paper trays. * **Consumer Electronics:** CD/DVD player trays and retractable panels. * **Automotive:** Glove boxes, ash trays, and overhead sunglass holders. * **Furniture:** Soft-close drawers and cabinet doors. --- ## 5. Selection Considerations If you are replacing or integrating an FRT-62-R, consider the following: * **Torque Direction:** Some dampers are one-way (damping in only one direction) while others are two-way. * **Temperature Sensitivity:** Because they use silicone oil, the damping force can become stiffer in cold environments and looser in hot environments. ---
