In the RFID application scenario, if a conventional RFID tag is attached to the surface of a metal object to read, the performance will drop sharply, and it may not be read. RFID anti-metal tags can solve the problem that conventional tags cannot be read when attached to metal surfaces, and it is a good helper for metal asset management.

So, what are the common types of RFID UHF anti-metal tags? How to distinguish and purchase them correctly? Come and learn about them with RZX Technology!

RFID anti-metal tags are distinguished from materials, they can be divided into hard tags, soft tags, special tags, etc.

Common anti-metal hard labels are composed of UHF white label + PET foam (1cm thick) + 3M glue, the purpose is to increase the distance between the metal surface and the label, so as to achieve the anti-metal function;

The common anti-metal soft tag is also the RFID flexible anti-metal tag that is currently used in asset management. It adopts advanced anti-metal antenna design circuit design + aluminum foil 0.8-1mm foam wrap, thickness 1-1.2mm, and it has a certain Flexible, bendable, used on metal surfaces, with good resistance to metal, excellent performance, good directionality, reading distance, etc., suitable for pasting on curved assets such as metal cylinders, and can be used in RFID asset management, cylinder tracking, and transportation Control, logistics management, dangerous goods management, etc.

Note: The general printer can print 0.06-0.28mm thickness; but the printer that prints flexible anti-metal labels must support the printing thickness 1.3-1.4mm, and support the printer type: Zebra ZT410/Silver line Printronix SL4M

Common materials for RFID special tags include PCB anti-metal tags, ceramic anti-metal tags, ABS anti-metal tags and RFID cable tie tags. Come and follow with RZX Technology to understand the design principles and label applications of RFID special tags!

PCB label design principle: there are two metal layers at the front and back, humidified inlay in the middle, commonly thickness 2-3mm

PCB anti-metal label application: suitable for installation on car license plates, and also suitable for outdoor power equipment inspections, steel tower and telephone pole inspections, elevator inspections, pressure vessel cylinders, steam cylinders, product tracking and asset management of various electric household equipment , Logistics management, process management of auto parts.

RFID ceramic tag is packaged with a special ceramic substrate and can be installed on the surface of a metal material. It has strong corrosion resistance and is suitable for harsh working environments. Mainly used in component tracking and asset management. 200 degrees temperature resistance, strong resistance to human body interference (21x21mm size can be readable up to 2 meters on human skin)

ABS anti-metal labels generally use ultrasonic over-injection, which has a slightly weaker water resistance; there are also wet inlays attached to the inside of the front, 10mm from the bottom, which is low in cost; and the package PCB board (5-6 pieces) is packaged with ABS engineering plastics. Sun protection, water resistance, high temperature resistance, etc., are widely used in logistics management. It can realize the informationization and modernization of logistics management, improve the level and efficiency of logistics management, and reduce management costs. Main application areas: logistics pallet labels are mostly used in logistics management, luggage, pallets, containers, shelves, equipment, fixed assets and other management.

RFID UHF cable tie tags mostly use tail nylon material + ABS shell to encapsulate the wet Inlay. The tail nylon needs to absorb enough water and needs to be boiled before leaving the factory. It is no problem if the south is not boiled, but in the case of extremely low temperatures in the north, Bending is easy to break, of course, there is also temperature-resistant nylon to choose from, so you need to distinguish between areas when purchasing.
