The **FRT-GZ-R** series refers to a specific line of **rotary dampers** (often manufactured by companies like Fuji Latex). These components are mechanical in application but are essential in electronic hardware design for controlling motion. Below is a breakdown of its electronic-relevant characteristics and specifications. ### 1. Overview of the FRT-GZ-R A rotary damper provides resistance to a rotating shaft to slow down motion. In electronic devices, these are used to provide a "premium feel" or to protect delicate electronic sensors/screens from slamming. | Feature | Specification Details | | :--- | :--- | | **Type** | Partial Rotation / Continuous Rotation | | **Damping Direction** | Clockwise (R) or Counter-clockwise (L) | | **Material** | Polycarbonate (PC) / Polyacetal (POM) | | **Working Fluid** | Silicone Oil | | **Operating Temp** | -10°C to 50°C | --- ### 2. Internal Components & Mechanism While the device is not powered by electricity, its internal design is critical for integration into electronic assemblies: * **Rotor:** The internal part connected to the gear. * **Stator:** The outer housing fixed to the device chassis. * **Silicone Oil:** The viscous fluid that creates the shearing force (torque). * **Gear Interface:** Typically uses a standardized pitch (e.g., 0.8 module) to interface with motorized or manual electronic drive systems. --- ### 3. Application in Electronics These parts are ubiquitous in modern consumer electronics. Here are the primary use cases: #### A. Automotive Infotainment Used in retractable GPS screens or motorized dashboard covers to ensure smooth, silent deployment. #### B. Home Appliances Used in the control panels of washing machines or the "soft-close" lids of smart toilets and ovens to prevent mechanical shock to internal PCB boards. #### C. Peripheral Hardware Applied to CD/DVD tray mechanisms or the flip-up covers of high-end audio amplifiers. --- ### 4. Technical Performance Data The "R" in the model name usually signifies **Clockwise Damping**. Below is a sample torque table for this series: | Model Code | Torque (N·m) | Gear Teeth Count | | :--- | :--- | :--- | | FRT-G2-202G1 | 0.20 ± 0.04 | 11 | | FRT-G2-302G1 | 0.30 ± 0.05 | 11 | | **FRT-GZ-R** | **Custom/Variable** | **Varies (11-14)** | --- ### 5. Integration Considerations When designing an electronic enclosure for this part: 1. **Alignment:** Ensure the gear mesh is precise to avoid skipping, which can cause vibration noise in sensitive electronic housings. 2. **Heat Dissipation:** Although passive, repetitive use generates friction heat in the silicone oil, which may slightly alter the torque (viscosity drops as temperature rises). 3. **Static Control:** Ensure the plastic housing of the damper does not build up a static charge near sensitive ICs.
