The **FRT-Z1-R/Q** series refers to a specific line of **Rotary Dampers** produced by manufacturers like *Fuji Latex*. These are passive mechanical-electronic components used to control the motion of opening and closing mechanisms through viscous drag. --- ## 1. Technical Specifications The FRT-Z1 series is designed for small-scale applications where smooth, controlled movement is required. | Feature | Specification Details | | :--- | :--- | | **Model Type** | FRT-Z1-R (Clockwise) / FRT-Z1-Q (Counter-clockwise) | | **Torque Range** | 0.2 N·m to 1.0 N·m (varies by specific sub-model) | | **Rotation Angle** | 360° (Continuous) | | **Material** | Polycarbonate (Body), Polyacetal (Gear/Shaft) | | **Operating Temp** | 0°C to 50°C | | **Damping Oil** | Silicone Oil | --- ## 2. Key Electronic & Mechanical Components ### A. Internal Viscous Fluid The core of the "electronic" control in these dampers is actually **Silicone Oil**. - **Function:** As the shaft rotates, the oil creates resistance against the internal vanes. - **Consistency:** The viscosity of the oil determines the damping force. It is engineered to maintain consistent torque even under varying environmental temperatures. ### B. Directional Logic (R vs. Q) The suffix in the part number indicates the direction of the damping force: - **FRT-Z1-R:** Damping occurs in the **Right (Clockwise)** direction. The opposite direction allows free movement (one-way clutch mechanism). - **FRT-Z1-Q:** Damping occurs in the **Left (Counter-clockwise)** direction. ### C. Integrated Gear System The part usually features a small spur gear on the shaft. - **Module:** Usually 0.5 or 0.8. - **Purpose:** To interface with the rack or gear of a tray (like a CD-ROM or a car cup holder) to convert linear motion into rotary resistance. --- ## 3. Common Applications These parts are widely used in consumer electronics and automotive interiors: 1. **Consumer Electronics:** Slow-release trays for CD/DVD players and soft-close lids for printers. 2. **Automotive:** Glove boxes, ash trays, and retractable cup holders. 3. **Home Appliances:** Control panels that flip out or lids that close softly to prevent noise and impact damage. --- ## 4. Maintenance and Usage Notes * **No External Power:** These are passive components; they do not require electricity to operate. * **Torque Decay:** Over millions of cycles, the silicone oil may degrade, leading to a "faster" close. * **Alignment:** Ensure the gear mesh is aligned; side-loading the shaft can cause the internal seals to leak oil.
