IDTS-D33 UHF On-Metal PCB RFID Tag 33 x 27 mm Two-Hole Mount for Asset Tracking

The IDTS-D33 is an on-metal (anti-metal) passive UHF RFID tag from IDentium, built on a PCB substrate and shaped as a round disc with flattened top and bottom edges. It measures 33 x 27 mm with a 4 mm thickness at its highest point, and carries two mounting holes of 3.2 mm diameter spaced 24 mm apart, so it can be fixed mechanically onto the metal assets that defeat ordinary paper and PET labels. Mounted directly on metal it reads at approx. 4 m, giving Indian warehouses, plants, depots and IT teams a practical, repeatable way to audit steel and aluminium assets without touching them.

Applications

• Tool crib and calibration control - fix onto hand tools, jigs, fixtures and gauges so issue, return and calibration due-dates are logged by scan rather than by register.
• Gas cylinder tracking - the 33 x 27 mm footprint and 24 mm two-hole mount suit cylinder collars and neck rings for industrial and medical gas fleets, refill cycles and safety audits.
• IT asset audits - tag servers, switches, UPS units, rack rails and metal enclosures for annual physical verification without unracking equipment.
• Utility and electrical assets - distribution panels, meter boxes, cable drums, switchgear cabinets and pole-mounted metal fittings for field inspection rounds.
• Manufacturing plant and WIP - motors, pumps, gearboxes, moulds, dies and trolleys, including areas that run warm, within the -20 C to +150 C operating range.
• Railways and depots - metal fittings, brake gear, spares bins and maintenance items that move between depot and workshop.
• Pharma and process plant - stainless steel vessels, racks, trolleys and process skids that need traceable identification on a metal body.

Why Choose This Tag

• Built for metal, not adapted to it. This is an anti-metal design, so the surface that normally kills a UHF read becomes the mounting surface - around 4 m on metal from a compact 33 x 27 mm body.
• Bolt it on and forget the adhesive. Two 3.2 mm holes on a 24 mm pitch allow mechanical fixing, which suits oily, hot or frequently wiped-down assets where stick-on labels tend to lift.
• Wide operating temperature. Rated -20 C to +150 C, so it can go on assets in cold stores as well as on warm machinery and process equipment.
• Standards-based and reader-agnostic. ISO18000-6C with 128 bits of EPC memory for your own asset numbering scheme plus 96 bits of TID - it works with the fixed readers, handhelds and middleware you already run.
• Small enough to fit, thick enough to matter. At 4 mm at its highest point, the tag adds very little to a panel face, cylinder collar or machine housing while keeping a low, snag-resistant profile.

Read range figures are typical values measured on a metal surface. Actual performance varies with reader output power, antenna type and orientation, the mounting surface and the surrounding RF environment. We recommend a short on-site trial with your own reader before bulk deployment.
