IDTS-D28 28 mm Round PCB On-Metal UHF RFID Tag, Twin Mounting Holes, Tool & Cylinder Tracking

The IDTS-D28 is a compact 28 mm round black PCB on-metal UHF RFID tag from IDentium, built for asset identification directly on metal surfaces. Its anti-metal PCB construction delivers a read distance of approx. 3.5 m on metal, while two 3.2 mm mounting holes at 22.4 mm spacing allow the tag to be mechanically fixed to tools, cylinders, panels and machine assets. With an operating temperature rating of -20 C to +150 C and a slim 2.6 mm profile, it suits Indian warehouses, tool cribs, utilities and manufacturing plants where a small, permanently mounted, machine-readable identity is needed on metal.

Applications

• Tool cribs and workshops: identification of spanner sets, torque tools, jigs and fixtures that offer a flat metal face large enough for a 28 mm disc.
• Gas cylinder tracking: mounting on cylinder collars, shoulder plates and valve guards for issue, return and refill cycles at industrial gas depots.
• IT asset audits: tagging server racks, rack rails, network switches and UPS cabinets so annual audits can be completed by walk-past scanning.
• Utilities and electrical infrastructure: distribution panels, switchgear doors, meter boxes and transformer housings across substation and feeder inspection rounds.
• Manufacturing moulds, dies and fixtures: identification of tooling and machine assets on production lines that stay within the -20 C to +150 C rating.
• Railways and depots: component, spares and fixture tracking on metal parts held in maintenance yards and stores.
• Pharma and process plants: equipment and utility asset identification on valves, pipe flanges, trolleys and stainless-steel fixtures.

Why Choose This Tag

• Built for metal, not adapted to it. The anti-metal PCB construction is intended for direct mounting on metal assets and reads at approx. 3.5 m on metal, so aisle-level and doorway reads stay practical.
• Mechanically fixed, not stuck on. Two 3.2 mm mounting holes on a 22.4 mm spacing let the tag be bolted or riveted down - a better fit than adhesive for greasy, hot or frequently handled assets.
• Wide -20 C to +150 C rating. A single tag type can cover cold stores, ambient warehouses and hot production areas within that range, simplifying your spares list.
• Small 28 mm round footprint. At 2.6 mm thick at the raised central dome, it fits on tool faces, cylinder collars and panel edges where a rectangular pallet-sized tag will not sit.
• Standards-based, serialisable identity. ISO18000-6C with a U8 chip, 128-bit EPC and 96-bit TID works with standard UHF handhelds and fixed readers, and supports serialised numbering schemes for audits.

Read range is a typical figure and will vary with the reader and antenna used, transmit power, the mounting surface and orientation, and the surrounding environment. We recommend a site trial with your own reader before large deployments.
