The **MH15TAG-R** is a specific Radio Frequency (RF) identification device, commonly associated with **Passive RFID Tags** used in industrial automation, logistics, and asset tracking. Below is a detailed breakdown of its electronic components and technical specifications. --- ## 1. Core Component Breakdown The device is a passive electronic assembly, meaning it does not contain a battery. It operates by harvesting energy from an RFID reader's electromagnetic field. | Component | Function | | :--- | :--- | | **IC (Integrated Circuit)** | The "brain" containing the memory bank, logic for data processing, and the modulator. | | **Internal Antenna** | A copper or etched aluminum coil designed to receive 13.56 MHz or UHF signals (depending on the specific series variant). | | **Encapsulation** | Usually a ruggedized resin or plastic (PPS/Epoxy) to protect the electronics from heat, pressure, and chemicals. | | **Capacitor** | Integrated into the IC to store the small amount of energy harvested from the reader to power the chip. | --- ## 2. Technical Specifications While specific data can vary by manufacturer (often associated with brands like **Turck** or **Balluff** in industrial contexts), the standard parameters for the MH15TAG-R series are: ### Electrical Properties * **Operating Frequency:** Typically **13.56 MHz** (High Frequency / HF) or **860-960 MHz** (UHF). * **Memory Type:** EEPROM (Electrically Erasable Programmable Read-Only Memory). * **Data Retention:** Usually rated for 10+ years. * **Read/Write Cycles:** Typically 100,000 cycles. ### Physical/Environmental Properties * **Mounting:** Often designed to be embedded in metal (Flush mount) or attached to surfaces. * **Protection Rating:** Usually **IP67 or IP68** (Waterproof and Dustproof). * **Temperature Range:** -25°C to +85°C (Standard), though some "R" (Rugged) versions support higher peaks. --- ## 3. Operating Principle 1. **Energy Harvesting:** The reader sends out a signal via its antenna. 2. **Induction:** The MH15TAG-R antenna picks up the signal; the magnetic field induces a small current in the tag's coil. 3. **Activation:** The IC wakes up and processes the command from the reader. 4. **Backscatter:** The tag modifies its internal impedance to reflect the signal back to the reader with the stored ID or data. --- ## 4. Application Use Cases * **Tool Identification:** Tracking CNC bits or industrial molds. * **Automotive Assembly:** Tracking chassis through various stages of the production line. * **Asset Management:** Identifying heavy machinery or containers in harsh environments.
