The **FRT-05-R** is a specific model of a **Rotary Damper**, typically manufactured by companies like **Bansbach Easylift** or **Fuji Latex**. While it is often categorized under "Electronic Parts" in supply chain databases because it is frequently used in consumer electronics (like CD trays or soft-close lids), it is technically a **mechanical component** designed to control the speed and smoothness of motion. --- ### 1. Technical Specifications The "05" in the part number generally refers to the torque rating. Below are the typical technical parameters for this series: | Parameter | Specification | | :--- | :--- | | **Part Number** | FRT-05-R | | **Type** | Rotary Damper (Continuous Rotation) | | **Direction** | Right-Hand (Clockwise) | | **Torque Range** | ~4.0 to 7.0 N·cm (0.4 to 0.7 kgf·cm) | | **Material** | Polycarbonate (Body), Polyacetal (Gear/Rotor) | | **Damping Oil** | Silicone Oil | | **Operating Temp** | 0°C to 50°C | --- ### 2. Internal Components & Mechanism Although it has no wires, its performance is critical for the physical interface of electronic devices. 1. **Housing/Body:** A plastic casing that contains the damping fluid. 2. **Rotor:** The internal spinning component that creates resistance. 3. **Damping Fluid (Silicone Oil):** The "electronic-grade" viscosity of this oil provides the resistance. The shear force of the oil between the rotor and the housing creates the damping effect. 4. **Gear:** Usually a small spur gear on the exterior that meshes with a rack or another gear in the device. --- ### 3. Key Characteristics * **Directionality ("-R"):** This specific model provides damping in the **Clockwise (Right)** direction. It typically allows free rotation or significantly less resistance in the Counter-Clockwise direction. * **Soft-Close Function:** It prevents the "snapping" sound or impact when a door or drawer is closed. * **Maintenance-Free:** These are sealed units designed for millions of cycles without needing lubrication. --- ### 4. Common Applications in Electronics The FRT-05-R is commonly found in: * **Audio/Visual Equipment:** Slow-opening CD/DVD trays and cassette decks. * **Automotive Interiors:** Ash trays, cup holders, and glove box compartments. * **Home Appliances:** Control panel covers on washing machines or microwaves. * **Office Hardware:** Printer covers and scanner lids. ---
