IDTS-D08 8mm Round PCB Anti-Metal UHF RFID Tag, 4mm Thick, for Tools & IT Assets

The IDTS-D08 is a miniature on-metal (anti-metal) passive UHF RFID tag from IDentium, built on a PCB substrate in a round disc form just 8 mm across and 4 mm thick. It is small enough to sit on a fingertip, which makes it a practical identity marker for metal items that are far too small for a conventional asset label — hand tools, precision instruments, fittings and electronic hardware. Despite the size, it is engineered to work while mounted directly on metal, with a typical read of approx. 1.5 m on metal, and it carries a 1.4 mm hole in the disc face that many buyers use for mechanical fixing.

Applications

• Tool crib and calibrated tool control — identify spanners, torque wrenches, drill chucks, gauges and small hand tools at issue and return, where the tag must be tiny enough not to interfere with the tool.
• IT asset audits — tag laptops, docking stations, switches, routers, server rails and other metal-bodied hardware for annual physical verification without opening racks.
• Jigs, fixtures, dies and moulds — permanent identity for tooling on the shop floor in Indian manufacturing and auto-component plants, where the -20 C to +150 C range suits warm production environments.
• Valves, fittings and small utility hardware — discreet identification for metal fittings on utility and process lines that are inspected on a route.
• Surgical and precision instrument tracking — track small stainless instruments and trays through hospital and pharma workflows where a full-size asset plate simply will not fit.
• Electronics and PCB-level traceability — attach to metal chassis, enclosures and sub-assemblies for work-in-progress tracking through assembly and test.
• Railway and maintenance spares — identify small metal components, couplings and inspection points in depot and workshop stock control.

Why Choose This Tag

• Reads while sitting on metal. This is an anti-metal design, so it goes directly onto steel and other metal surfaces where an ordinary UHF label would fail, and still gives around 1.5 m on metal.
• 8 mm diameter, 4 mm thick. One of the smallest on-metal formats we stock — it fits on tool shanks, instrument handles and equipment faces that cannot accept a larger plate.
• Wide -20 C to +150 C operating range. Covers cold-store handling at one end and hot workshop and process areas at the other.
• Standards-based ISO18000-6C, with 128-bit EPC and 96-bit TID. Works with the handheld and fixed UHF readers already deployed across Indian warehouses and plants, and the factory-programmed TID gives every tag a unique reference.
• 1.4 mm hole for mechanical fixing. The hole in the disc face lets you fasten the tag mechanically on assets where you want a fixing rather than relying on a bond alone.

Read range is a typical figure, not a guarantee: actual performance varies with the reader and antenna used, transmit power, the mounting surface and the surrounding environment. We recommend a sample trial on your own assets before bulk deployment.

Frequently asked questions

How small is the IDTS-D08 and what is it used for?

It is a round PCB disc just 8 mm across and 4 mm thick, small enough to sit on a fingertip. That makes it a practical identity marker for metal items far too small for a conventional asset label, including hand tools, precision instruments, fittings and electronic hardware that still need to be audited and traced.

Will it read when mounted on metal?

Yes. It is an on-metal or anti-metal design engineered to work while mounted directly on a metal surface, with a typical read of approximately 1.5 m on metal. A standard label tag would detune in the same position, which is why on-metal tags exist. Range varies with reader power, antenna and the asset itself.

Can the tag be fixed mechanically instead of glued?

Yes. The disc face carries a 1.4 mm hole that many buyers use for mechanical fixing, so the tag can be pinned or screwed rather than depending on adhesive alone. That matters on tools and instruments that are handled constantly, cleaned often, or stored in ways that would eventually lift a stuck on tag.

What is the price and can I order small quantities?

Pricing depends on the volume ordered, so please check the listed price on this page or request a bulk quote for larger runs. Identium is a BIS and WPC certified Indian manufacturer, so bulk and OEM pricing, custom encoding, samples for evaluation and pan India shipping are all available on request.
