The **FJT-96-R** is a specific model of a **Rotary Joint (Slip Ring)** or high-frequency connector assembly, commonly used in industrial automation, robotics, and communication systems. Below is a detailed breakdown of its electronic and mechanical parts. --- ### 1. Overview and Core Function The FJT-96-R serves as an electromechanical interface that allows the transmission of power and electrical signals from a stationary structure to a rotating structure. It is designed to prevent wires from tangling or breaking during continuous 360-degree rotation. ### 2. Key Electronic & Mechanical Components | Component | Function | Material/Specification | | :--- | :--- | :--- | | **Conductive Rings** | The internal tracks that carry the electrical current. | Usually Gold-plated or Silver-plated Copper. | | **Brushes** | Stationary contacts that slide against the rotating rings. | Precious metal fiber (Gold-on-Gold) for low noise. | | **Housing/Shell** | Protects the internal circuitry from environmental interference. | Aluminum alloy or Engineering Plastics (IP-rated). | | **Bearings** | Ensures smooth mechanical rotation of the internal shaft. | Precision stainless steel ball bearings. | | **Lead Wires** | The input/output wiring for the stationary and rotating sides. | Color-coded Teflon (PTFE) or PVC insulated wire. | --- ### 3. Technical Characteristics The "96" in the part number often refers to specific technical dimensions or the number of circuits (channels), though this can vary by manufacturer. Key electronic specs typically include: * **Contact Resistance:** Extremely low (typically <0.01Ω) to ensure signal integrity. * **Dielectric Strength:** Usually rated for 500V AC @50Hz between each circuit. * **Insulation Resistance:** Usually >1000MΩ at 500VDC. * **Electrical Noise:** Minimal (under 10mΩ) to support high-speed data transmission (Ethernet, USB, or PLC signals). ### 4. Applications The FJT-96-R is typically integrated into the following electronic systems: 1. **CCTV/Gimbal Systems:** Rotating cameras that require continuous power and video signal. 2. **Robotic Arms:** Providing power to end-effectors while the joints rotate. 3. **Wind Turbines:** Transferring sensor data and power from the blades to the stationary nacelle. 4. **Packaging Machinery:** Rotary indexing tables and filling machines. --- ### 5. Maintenance and Safety * **Wear and Tear:** Since it uses physical contact (brushes), the electronic performance may degrade over millions of rotations due to carbon buildup. * **Signal Interference:** It is often shielded to prevent EMI (Electromagnetic Interference) from affecting sensitive data channels.
