IDTS-1204 UHF On-Metal RFID PCB Tag 12 x 4 x 2.8 mm Anti-Metal Micro Tag for Tools & Electronics

The IDTS-1204 is a fingertip-sized passive UHF on-metal RFID tag built on a PCB body measuring just 12 x 4 x 2.8 mm. It is designed for the items most RFID tags are simply too big for — circuit boards, hand tools, instruments, jigs and small metal parts — while still delivering an anti-metal read of approx. 1.5 m on metal. The black rectangular bar form factor with solder pads at both ends lets it sit discreetly on or inside compact assemblies.

Applications

• PCB and electronics traceability — tagging individual boards, modules and sub-assemblies through production, test and RMA, where a 12 x 4 mm footprint fits alongside components.
• Tool cribs and small hand tools — issue-and-return tracking of spanners, drivers, drill chucks, torque tools and cutting tools in workshops and MRO stores.
• Surgical, dental and laboratory instruments — item-level identification of small stainless instruments in hospital CSSD and pharma lab inventories.
• Jigs, fixtures, moulds and dies — identifying tooling on the shop floor in automotive, engineering and manufacturing units.
• IT asset audits — discreet tagging of laptops, servers, switches, routers and other metal-cased equipment for annual physical verification.
• Test and calibration equipment — linking gauges, meters and probes to calibration due dates in utilities, railways and QA labs.
• Small metal components and fittings — valves, connectors, couplings and spares that need identification but offer very little flat surface area.

Why Choose This Tag

• Genuinely miniature. At 12 x 4 x 2.8 mm it goes on assets that cannot accept a standard on-metal tag, and it can be placed where a larger label would foul moving parts or block a working surface.
• Built for metal. The tag is an anti-metal design and is specified for mounting on metal surfaces, delivering approx. 1.5 m on metal — ample for handheld reader audits and gate-side checks in aisles and stores.
• Wide -20 C to +150 C operating range.
• ISO18000-6C with usable memory. 128-bit EPC and 96-bit TID support standard passive UHF deployments, and the 0 / 512-bit user memory option allows on-tag data where your application needs it.
• Practical PCB construction. The black rectangular PCB bar carries solder pads at both ends, giving integrators a straightforward way to fix the tag into compact electronic and mechanical assemblies.

Read range is an approximate figure and will vary in practice with the reader and its output power, the antenna used, the mounting surface and the surrounding environment. We recommend a site trial on your own assets before finalising quantities.
