The **MH52TAG-R** is an electronic component primarily classified as a **High-Frequency RFID (Radio Frequency Identification) Tag** or Transponder, often utilized in industrial automation and logistics tracking. It is specifically designed to function within the **HF (13.56 MHz)** range. --- ### 1. Technical Specifications The following table outlines the key electronic and physical characteristics of the MH52TAG-R: | Feature | Specification | | :--- | :--- | | **Operating Frequency** | 13.56 MHz (HF) | | **Protocol** | ISO/IEC 15693 (or ISO 14443 depending on variant) | | **Memory Capacity** | Typically 1k to 2k bits (EEPROM) | | **Read Range** | Short to Mid-range (dependent on antenna size) | | **Form Factor** | Compact, likely encapsulated for durability | | **Operational Temp** | -25°C to +85°C (Standard Industrial) | --- ### 2. Core Electronic Components The internal architecture of this tag consists of three primary elements: 1. **RFID IC (Integrated Circuit):** The "brain" of the tag. It contains the logic circuitry for modulation/demodulation of the RF signal and the EEPROM memory used to store unique identification numbers and user data. 2. **Antenna Coil:** A copper wire coil or etched aluminum trace tuned to resonance at 13.56 MHz. This coil uses **Inductive Coupling** to harvest power from the reader's magnetic field, meaning the tag is **passive** (no battery required). 3. **Capacitor:** Integrated into the IC or as a surface mount component to form a resonant LC circuit with the antenna, ensuring maximum power transfer efficiency at the specific frequency. --- ### 3. Functional Features * **Anti-Collision Support:** Allows multiple tags to be read simultaneously within the reader's field without signal interference. * **Passive Operation:** Since it lacks an internal power source, it has an almost infinite shelf life and is activated only when within range of an RFID reader. * **Robustness:** The "-R" designation often refers to "Ruggedized" or a specific "Read-only/Read-write" configuration intended for harsh environments (e.g., vibration, moisture, or chemical exposure). --- ### 4. Common Applications * **Asset Tracking:** Monitoring tools or equipment in a factory. * **Access Control:** Used in key fobs or security badges. * **Production Line Management:** Tracking parts through various stages of assembly.
