The **MH12TAG-R** refers to a specific type of **Passive RFID Tag** (Radio Frequency Identification) designed for industrial and logistical tracking. These tags are engineered to be durable and are often used in environments where standard labels would fail. --- ## 1. Technical Specifications Below are the typical electronic and physical characteristics of the MH12TAG-R series: | Feature | Specification | | :--- | :--- | | **Technology** | Passive RFID (No battery required) | | **Frequency Range** | 860 MHz – 960 MHz (UHF - Ultra High Frequency) | | **Protocol** | EPC Class 1 Gen 2 / ISO 18000-6C | | **Read Range** | 1 to 5 meters (depending on reader power/environment) | | **Memory Capacity** | Typically 96-bit to 128-bit EPC | | **Operating Temp** | -40°C to +85°C | | **Material** | Ruggedized ABS or Encapsulated Resin | --- ## 2. Core Electronic Components The device is composed of three primary electronic elements: ### A. The IC (Integrated Circuit / Microchip) The "brain" of the tag. It contains a small amount of memory to store the Unique Identifier (UID) or Electronic Product Code (EPC). It is designed to harvest power from the radio waves emitted by an RFID reader. ### B. The Antenna The antenna is the largest part of the internal circuitry. It is tuned to the **UHF (860-960 MHz)** band. In the MH12TAG-R, the antenna is usually etched or printed on a substrate, designed to capture electromagnetic energy and transmit the chip's data back to the reader. ### C. Impedance Matching Circuit A small network between the chip and the antenna ensures that the maximum amount of power is transferred from the antenna to the IC, which is critical for long-range reading. --- ## 3. Key Electronic Features * **Passive Operation:** It has no internal battery. It is powered by the electromagnetic field of the reader. * **Anti-Collision:** The electronics support protocols that allow a reader to identify hundreds of these tags simultaneously without signal interference. * **Durability (The "R" Suffix):** The "R" usually denotes "Ruggedized." The electronic components are encased in a protective shell to resist moisture, impact, and chemical exposure. --- ## 4. Common Applications * **Asset Tracking:** Monitoring tools, containers, or machinery. * **Inventory Management:** Real-time tracking of goods in a warehouse. * **Supply Chain Logistics:** Tracking pallets or crates through international shipping routes.
