IDTS-D25 25 mm Round PCB On-Metal UHF RFID Disc Tag, 4 mm Thick, Two Mounting Holes, Asset Tracking

The IDTS-D25 is a 25 mm round black PCB disc tag built for one job that ordinary label tags cannot do: carrying a readable UHF identity while mounted directly on metal. Its anti-metal construction returns a read range of approx. 4 m on metal, and two pre-drilled 3.2 mm holes let it be fixed mechanically to tools, cylinders, panels and plant equipment instead of relying on adhesive alone. With an operating range of -20 C to +150 C, it suits assets that see heat as part of normal working life.

Applications

• Tool crib and hand-tool tracking - a 25 mm disc mounts on spanners, torque tools, dies and jigs without covering the working face of the tool.
• Gas cylinder identification - fits the collar or shoulder area of industrial and medical gas cylinders for filling, testing and return cycles.
• IT asset audits - tag server racks, switches, UPS units and metal cabinets so annual audits can be walked rather than typed.
• Utilities and electrical infrastructure - identify switchgear cabinets, distribution panels, meter boxes and feeder pillars during inspection rounds.
• Plant and maintenance engineering - motors, pumps, gearboxes and valve bodies get a permanent machine-readable identity for preventive maintenance logs.
• Manufacturing fixtures and heat-process lines - suits fixtures, carriers and moulds on lines where tooling is exposed to elevated process temperatures within the tag's stated range.
• Railways, pharma and returnable metal assets - depot equipment, stainless trolleys, metal bins and returnable containers that move between locations and need repeat identification.

Why Choose This Tag

• Built to work on metal. This is an anti-metal tag, not a general-purpose label pressed into service - it delivers approx. 4 m on metal, the surface where plain inlays typically fail.
• Wide -20 C to +150 C operating range. The specified window covers cold stores, outdoor yards in Indian summers and hot tooling alike, so one part number can serve several areas of a plant.
• Mechanical mounting, not just stick-and-hope. Two 3.2 mm holes on a 19.5 mm spacing allow bolted or riveted fixing to assets that are washed, handled roughly or in constant motion.
• Compact 25 mm round, 4 mm profile. Small enough for tools, valve bodies and panel doors where a large rigid tag would foul clearances or get knocked off.
• Standards-based data structure. ISO18000-6C with 128-bit EPC and 96-bit TID means it works with standard UHF handhelds and fixed readers, and the factory TID gives every unit a unique reference for audit trails.

Read range is a typical figure, not a guaranteed maximum. Actual performance varies with the reader and its transmit power, the antenna used, the size and shape of the metal surface the tag is mounted on, and the surrounding environment. We recommend a short on-site trial with your own reader before committing to a large rollout.
