The **V680-HS65-R 2M** is a high-performance RFID Antenna (Read/Write Head) manufactured by Omron. It is part of the V680 series, designed for industrial automation and data tracking. --- ## Technical Specifications The "2M" in the model name indicates a **2-meter** robotic (high-flex) cable length. | Feature | Specification | | :--- | :--- | | **Transmission Frequency** | 13.56 MHz | | **Shape** | Square (Rectangular) | | **Dimensions** | 100 x 100 x 30 mm | | **Cable Type** | Robot Cable (R-type) | | **Enclosure Rating** | IP67 (Water and Dust resistant) | | **Operating Temperature** | -10°C to +60°C | | **Indicator** | Operation indicator (Green/Orange) | --- ## Electronic & Functional Components ### 1. The Antenna Coil Inside the 100x100mm housing is a copper induction coil. It uses **Electromagnetic Induction** to communicate with the RFID tag. Because this is a square-shaped antenna, it provides a larger sensing area compared to cylindrical models, making it ideal for large palettes or moving conveyors. ### 2. Communication Interface The unit does not process data autonomously; it must be connected to a **V680 Controller** (such as the V680-CA5D or a PLC module). * **Power Supply:** Received from the controller via the 2M cable. * **Data Transfer:** High-speed serial communication between the head and the controller. ### 3. Indicator LED (Electronic Feedback) The head contains an integrated LED that provides real-time status: * **Green:** Power is ON / Standby mode. * **Orange:** Communication is in progress with an RFID tag. ### 4. Robotic Cable (2M) The "R" in the model name stands for **Robot Cable**. * **Electronic shielding:** The cable is shielded to prevent EMI (Electromagnetic Interference) from nearby motors or high-voltage lines. * **Flexibility:** It is designed to withstand millions of bending cycles, making it suitable for mounting on robotic arms. --- ## Read/Write Distances The electronic performance varies based on the RFID tag paired with it: | Paired RFID Tag | Max Read Distance | Max Write Distance | | :--- | :--- | :--- | | **V680-D1KP66T** | 25 to 100 mm | 25 to 100 mm | | **V680-D8KF68** | 25 to 150 mm | 25 to 150 mm | | **V680-D32KF68** | 25 to 150 mm | 25 to 150 mm | --- ## Installation Precautions * **Metal Interference:** Since it operates on a 13.56 MHz induction field, mounting the electronic head directly on metal will reduce communication distance. Use a non-metallic spacer if possible. * **Mutual Interference:** If two V680-HS65-R heads are placed close together, they may interfere. A minimum distance of 300mm–500mm is usually required.
