IDTS-D40 40mm Round PCB On-Metal UHF RFID Tag, 3mm Thick, Two-Hole Mount for Equipment & Asset Tracking

The IDTS-D40 is a 40 mm round PCB on-metal (anti-metal) UHF RFID tag from the IDentium / IDTS range at India RFID Store. It is built as a black circular disc, 3 mm thick, with two 3 mm mounting holes set 34 mm apart centre-to-centre, so it can be mechanically fixed to metal equipment rather than relying on adhesive alone. Built on the Impinj Monza R6-P chip and the ISO18000-6C air interface, it delivers a read distance of approx. 2 m on metal, making it a practical choice for permanent identification of machinery, cabinets, cylinders and other metal assets across Indian plants, warehouses and utility networks.

Applications

• IT asset audits: server racks, network switches, UPS units and metal enclosures that need a fixed, machine-readable identity for annual verification.
• Plant and machinery maintenance: motors, pumps, gearboxes, compressors and valves where a tag stays with the asset through its service life.
• Tool cribs and workshops: jigs, fixtures, dies and larger hand tools issued and returned across shifts.
• Gas cylinders and metal drums: cylinder collars and drum bodies in industrial gas, LPG and chemical distribution fleets.
• Utilities: distribution panels, transformer enclosures, meter boxes and substation equipment on inspection rounds.
• Railways and rolling-stock workshops: component identification and trackside equipment cabinets.
• Pharma and manufacturing: stainless bins, trolleys, returnable metal totes and roll cages moving between production areas.

Why Choose This Tag

• Reads while mounted on metal. The anti-metal PCB construction is intended for metal surfaces and gives approx. 2 m read distance on metal - enough for aisle-side and walk-past inspection scanning.
• Fixed mechanically, not just stuck on. Two 3 mm holes at 34 mm centres let maintenance teams mount the tag permanently to equipment that gets washed, handled or moved.
• Wide operating range of -20 C to +150 C. Suits assets that sit near hot process equipment as well as cold-store and outdoor yard locations.
• Standards-based and reader-agnostic. ISO18000-6C with the Impinj Monza R6-P chip means it works with the fixed readers, handhelds and gate readers already used in Indian warehouses and plants.
• Compact 40 mm disc with usable memory. A 3 mm thick, 40 mm round black disc that still carries 128-bit EPC, 96-bit TID and 32-bit user memory for your own asset coding.

Read range figures are typical and will vary with the reader and antenna used, transmit power, orientation, and the surface the tag is mounted on. We recommend a short on-site trial on your own assets before large-volume deployment.
