The **MA64TAG-R** is a specific variant of the **MA64** series of high-frequency RFID (Radio Frequency Identification) tags, typically used in industrial automation, logistics, and asset tracking. It is designed to work within the **13.56 MHz (HF)** frequency band. --- ### 1. Key Technical Specifications The following table outlines the primary electronic and physical characteristics of the device: | Feature | Specification | | :--- | :--- | | **Frequency** | 13.56 MHz (HF) | | **Standard/Protocol** | ISO/IEC 15693 (High Frequency) | | **IC Type** | Often utilizes I-CODE SLIX or similar NFC/RFID chips | | **Memory Capacity** | Typically 1024 bits (896 bits user memory) | | **Read Range** | 0 to 100 cm (Dependent on reader/antenna size) | | **Operating Temperature** | -25°C to +85°C | | **Housing Material** | Robust Polyamide (PA6) or Epoxy | --- ### 2. Electronic Components & Structure The MA64TAG-R is a **passive** RFID tag, meaning it does not have an internal battery. Its electronic architecture consists of three main parts: #### A. The Integrated Circuit (IC) The "brain" of the tag. It manages the communication protocol, data encryption (if applicable), and data storage. It remains dormant until it enters the electromagnetic field of a reader. #### B. The Antenna (Inductive Coil) Because this is an HF (13.56 MHz) tag, the antenna is an inductive copper coil. * **Function:** It picks up the magnetic field generated by the reader. * **Power:** Through **Inductive Coupling**, the coil converts the magnetic field into electrical energy to power the IC. #### C. The Capacitor Small capacitors are often integrated into the IC or the substrate to tune the circuit to exactly 13.56 MHz, ensuring maximum energy transfer efficiency. --- ### 3. Key Electronic Features * **Anti-Collision:** The electronic logic allows multiple tags to be read simultaneously in the reader's field without signal interference. * **Data Retention:** The non-volatile memory (EEPROM) inside the electronic chip is typically rated to hold data for **up to 50 years**. * **Write Cycles:** The internal memory usually supports up to **100,000 write cycles**. --- ### 4. Application Context The "R" suffix often denotes specific mounting or ruggedization features (like a center hole for a screw or a specific resin coating). Electronically, these are used for: 1. **Tool Identification:** Tracking CNC bits or industrial tools. 2. **Access Control:** Embedded in tokens or key fobs. 3. **Maintenance Logging:** Storing service dates directly on the machine part.
