The **TW-R20-K2** is a compact, high-performance RFID (Radio Frequency Identification) tag, specifically categorized as a **Hard Tag** or **PCB Tag** designed for industrial applications. It is commonly associated with manufacturers like **Turck** or partners specializing in HF (High Frequency) identification systems. Below is the detailed breakdown of its electronic and physical specifications. --- ## 1. Core Technical Specifications The TW-R20-K2 operates in the High Frequency range and is built for durability in harsh environments. | Feature | Specification | | :--- | :--- | | **Operating Frequency** | 13.56 MHz (HF) | | **Communication Standard** | ISO 15693 | | **Chip Type** | NXP I-Code SLIX | | **Memory Capacity** | 1024 Bits (128 Bytes) | | **Read Range** | Up to 45 mm (dependent on reader/antenna) | | **Material** | Plastic (PA6), high durability | | **Operating Temp** | -25°C to +85°C | --- ## 2. Key Electronic Components ### A. The NXP I-Code SLIX Chip The "brain" of the tag is the **I-Code SLIX** integrated circuit. This chip is the industry standard for HF tags due to several electronic features: * **Anti-collision Support:** Allows multiple tags to be read simultaneously in the reader's field without signal interference. * **Data Retention:** Guaranteed data storage for up to 50 years. * **Write Endurance:** Rated for 100,000 write cycles. * **Password Protection:** Includes electronic locks for specific memory blocks to prevent unauthorized data overwriting. ### B. Integrated Antenna (Inductive Loop) The TW-R20-K2 contains an internal etched copper or printed antenna coil. * **Passive Powering:** It has no battery. It derives its power via **inductive coupling** from the magnetic field generated by the RFID reader. * **Form Factor:** The antenna is circular and optimized for the 20mm diameter housing to maximize energy transfer at 13.56 MHz. --- ## 3. Physical & Environmental Design The electronic parts are protected by a rugged housing to ensure functionality under mechanical stress. * **Housing Shape:** Disc/Coin shape (approx. 20mm diameter). * **Protection Class:** Usually rated **IP67 or IP68**, meaning the electronics are fully protected against dust and immersion in water. * **Mounting:** Designed to be mounted directly onto non-metallic surfaces. * *Note:* If mounted directly on metal, the electromagnetic field will be shorted, rendering the tag unreadable unless a "spacer" or specific "on-metal" version is used. --- ## 4. Application Areas Due to its electronic architecture, the TW-R20-K2 is ideal for: 1. **Tool Identification:** Tracking CNC bits or industrial machinery parts. 2. **Asset Management:** Monitoring the movement of small containers or pallets. 3. **Process Control:** Identifying workpieces on an automated assembly line. ---
