RFID Screw Tags,Metal RFID Tag, Non-Metal RFID Tag(Global promotion)RFID anti metal tag
features include: material 304 or 316, small size, long reading and writing distance, easy screw installation, chip embedded installation, corrosion-resistant resin glue protection, normal reading in low temperature environment
RFID Screw Tag is an intelligent label that embeds an RFID (Radio Frequency Identification) chip into the head or interior of a screw, combining fastening functionality with data storage/transmission capabilities. It interacts with a reader via wireless RF signals to enable unique identification, tracking, and management of objects, making it suitable for high-value equipment, industrial assets, or scenarios requiring concealed installation.
2. Working Principle
RFID Technology: The chip and antenna inside the tag receive RF signals emitted by the reader and reflect back stored data (e.g., ID, production information).
Frequency Types:
Ultra-High Frequency (UHF, 860-960 MHz): Long-range (up to 0-10m), supports batch reading, but requires anti-metal design.
3. Product FeaturesPhysical Characteristics
Material:
Screw Body: Stainless steel, titanium alloy, etc., offering corrosion resistance and high strength.
Tag Component: Epoxy resin/ceramic encapsulation, dustproof and waterproof (IP67/IP68).
Size: Compatible with standard screw specifications (e.g., M3-M12), customizable length.
Installation Method: Direct replacement for standard screws, no additional space required.
Electronic Performance
Chip Types:
Read-Only (e.g., UHF 860-960MHz).
Read-Write (e.g., HF 13.56MHz, 213): Storage capacity up to 144 bytes, supports data modification.
Anti-Interference Design: Metal isolation layer or magnetic materials to prevent signal attenuation in metal environments.
Temperature Range: -40°C to +150°C (industrial grade).
4. Application Scenarios
Industrial Asset Management: Track critical screws in machinery and pipeline valves to prevent loosening or theft.
Automotive/Aerospace: Record screw torque and installation time to ensure compliance.
Smart Buildings: Conceal marking of steel structures and curtain wall screws for easy maintenance.
Anti-Counterfeiting & Traceability: Tamper-evident design for luxury packaging and high-end electronics.
5. Technical Parameters
| Parameter | Typical Value |
|---|---|
| Frequency | 860-960 MHz (UHF) |
| Protocol Standard | ISO 18000-6C (EPC Gen2) |
| Read Range | 0.3-5m (depends on reader power) |
| Storage Capacity | 512 bit - 4Kbit |
| Protection Rating | IP68 |
| Tensile Strength | ≥50kN (depends on screw material) |
6. Advantages & LimitationsAdvantages
High Concealment: Appearance identical to standard screws, tamper-resistant.
Durability: Resistant to vibration, acids/alkalis, lifespan up to 10 years.
Efficient Management: Batch scanning improves inspection/inventory efficiency.
Limitations
Higher Cost: More expensive than standard RFID tags, suitable for high-value applications.
Metal Interference: Requires special design (e.g., ceramic antenna) to avoid signal shielding.
7. Selection Guide
Environmental Needs: Choose stainless steel + IP68 for outdoors; ceramic encapsulation for high-temperature environments.
Data Requirements: Opt for read-write chips if frequent data updates are needed.
Compatibility: Ensure frequency alignment with existing RFID systems.
