The **FRT-H0-R** is an electronic component primarily classified as a **Rotary Damper**. These parts are used to control the speed of a moving object through fluid resistance, providing a "soft-close" or "slow-release" mechanical movement in consumer electronics and automotive interiors. --- ### 1. Technical Specifications The FRT-H0-R belongs to the miniature rotary damper series, typically manufactured by companies like **Fuji Latex**. Below are the standard technical characteristics: | Feature | Specification | | :--- | :--- | | **Damper Type** | Continuous Rotation (360°) | | **Torque Direction** | Both directions (Clockwise and Counter-clockwise) | | **Torque Range** | Typically 0.1 to 0.4 N·cm (depending on specific sub-model) | | **Operating Temp** | 0°C to 50°C | | **Housing Material** | Polycarbonate or Polyacetal Plastic | | **Internal Fluid** | High-viscosity Silicone Oil | --- ### 2. Internal Mechanism The electronic/mechanical functionality of the FRT-H0-R relies on two main components: 1. **Rotor and Vane:** A small plastic rotor spins inside a sealed housing. 2. **Silicone Oil:** The housing is filled with silicone oil. As the rotor turns, the oil creates a shear force (viscous drag), which converts kinetic energy into thermal energy. 3. **Gears:** Most "R" suffix models come with a small plastic gear (pinion) attached to the shaft to interface with a rack or another gear. --- ### 3. Common Applications This part is ubiquitous in devices where a premium, controlled motion is required: * **Consumer Electronics:** CD/DVD tray loaders, sliding covers on printers, and camera compartments. * **Automotive:** Ash trays, glove box lids, and cup holders. * **Household:** Toilet seat covers, small trash can lids, and cabinet drawers. --- ### 4. Part Number Breakdown * **FRT:** Series prefix (Fuji Rotary Type). * **H0:** Size/Body style indicator. * **R:** Usually indicates the inclusion of a gear/pinion or a specific torque directionality (though H0 is typically bidirectional). --- ### 5. Installation Note When integrating the FRT-H0-R into a circuit or mechanical assembly, it is crucial to ensure that the **radial load** (the pressure pushing sideways on the gear) does not exceed the manufacturer's limit, as this will lead to oil leakage and failure of the damping effect.
