IDTS-RH30 UHF RFID Bolt Tag 30mm Hex Head, Metal Alloy + PCB + Epoxy, M5/M6 Stud, High-Temp Assets

The IDTS-RH30 is a passive UHF RFID bolt tag from IDentium, made for asset points that need a permanently fixed identity rather than a stick-on label. A 30 mm hexagonal head sits on an M5/M6 threaded stud for a total height of 25 mm, and the PCB inlay is potted in epoxy resin inside a metal alloy body. With an operating range of -40 C to +200 C, it is built for installations where the tag is expected to stay with the asset for its whole service life.

Applications

• Road-stud and ground-marker installations - the bolt form and 30 mm head suit kerb, paver and pavement reference points used by civic bodies and utility mapping teams.
• Machine and fixture identification - screwed into a tapped M5 or M6 hole on machine frames, jigs, fixtures and press tooling on the shop floor.
• High-temperature process areas - paint lines, powder-coating and curing ovens, and heat-treatment handling where the working temperature stays within the -40 C to +200 C range.
• Utility infrastructure points - valve chambers, pipeline markers, distribution poles and substation fittings that carry a threaded mounting boss.
• Heavy tooling and die tracking - dies, moulds and large hand tools in tool cribs where an adhesive label would not survive handling.
• Railway depot and trackside fixtures - permanent inspection and maintenance checkpoints that field staff scan on a walking round.
• Gas cylinder and pressure-vessel fittings - identification at collars, brackets or guard rings that provide a threaded mounting point.

Why Choose This Tag

• Wide -40 C to +200 C operating range lets one tag ID follow an asset through process areas that ordinary label tags are not rated for.
• M5/M6 threaded stud gives a mechanical fixing into a tapped hole, so the tag is fitted once and does not depend on adhesive or cable ties.
• NXP UCODE 8 chip with 128-bit EPC and 96-bit TID supports your own EPC numbering scheme alongside a factory-programmed TID for unique identification.
• Metal alloy + PCB + epoxy resin construction - the PCB inlay is potted in epoxy resin inside the metal alloy housing rather than laminated between films.
• Compact 30 mm hex head, 7 mm thick, 25 mm overall keeps the installed profile small at the mounting point while still reading at approx. 3 m depending on reader performance.

Read distance is a typical figure, not a maximum. Actual performance varies with the reader and antenna used, transmit power, antenna orientation, the mounting surface and any surrounding metal or liquid in the environment. We recommend a site trial with your own reader before bulk deployment.
