Xerafy - XS Dot (EU)

6 mm dot with full UHF capability – RFID for surgical instruments and micro tools

At just 6 mm in diameter and 2.50 mm in height, the Xerafy XS Dot X4102-EU000-H9 is one of the smallest UHF RFID hard tags available on the market. This round form factor was engineered specifically for applications where an elongated tag simply does not fit – surgical instruments with rotating grips, MRO tools with round mounts, narrow bores on maintenance equipment or attachment points on endoscopy components. If you are already operating a UHF | RAIN – RFID reader and want to bring the smallest tools and instruments into your capture strategy, the XS Dot closes the gap between classic micro tags and mounting on round components.

Inside, the Alien Higgs 9 IC delivers 48-bit TID, 96-bit EPC and 688-bit user memory. The fact that a tag of this size offers 688 bits of user memory is remarkable: tool IDs, calibration data, sterilisation cycles or maintenance status can be written directly to the instrument without relying on an external database. In the EU 865–868 MHz band, the tag reaches up to 1.50 m read range on metal – more than enough for near-field applications such as tool dispensing, instrument trolley scans or inventory checks on surgical trays.

The ceramic housing with epoxy potting provides mechanical stability and chemical resistance that clearly exceed what the form factor would suggest. With 5,447 kPa compression strength, IP68 rating and a survival temperature of −40 °C to +150 °C, the tag reliably withstands cleaning and reprocessing routines.

The following part number is available in the IDCRAFT online shop – this variant is designed for a specific use case:

• X4102-EU000-H9 – Xerafy XS Dot in the EU configuration for 865–868 MHz, equipped with Alien Higgs 9 IC, 688-bit user memory and a ceramic housing. Round micro form factor Ø 6 x 2.50 mm at just 0.34 g, IP68 rated, survival temperature −40 °C to +150 °C, 5,447 kPa compression strength. Read range up to 1.50 m on metal, attached via epoxy potting. The right pick for European hospitals, CSSD units, aerospace MRO operations and tool management departments that need to label the smallest surgical instruments and micro tools with RFID.

The key difference compared to the other XS variants lies in the geometry: while the XS Dash with its dash shape targets elongated tools and the XS Wedge is engineered for press-fit embedded mounting, the XS Dot offers the ideal round form factor for bores, cap mounts and rotating grips.

Technical Highlights

• EPC Gen2 / ISO/IEC 18000-63 compliant – works with all common UHF RFID readers and reader platforms
• Alien Higgs 9 IC with 688-bit user memory – stores tool IDs, calibration and maintenance data
• Up to 1.50 m read range on metal – suitable for near-field capture on instruments and micro tools
• 5,447 kPa compression strength, IP68 rating, survival up to +150 °C
• Round ceramic form factor Ø 6 x 2.50 mm at 0.34 g – smallest dot tag in the XS series

Applications

• Surgical instruments and endoscopy – RFID identification directly on rotating grips and round mounts
• MRO tool control in aerospace and rail workshops – tag attachment in bores and small cut-outs
• Hand tool tracking – round form factor fits on torque adapters and specialty tools
• Defense and weapon management – controlled capture of safety-critical small components

The Xerafy XS Dot brings a rare combination to the UHF | RAIN – RFID space: it is small enough for compromise-free integration into surgical and industrial micro components, yet does not give up user memory, compression strength or survival temperature in the process. Within the XS series, it is the variant for all use cases where a round tag geometry is the only viable route – whether for structural or ergonomic reasons.

Thanks to its EPC Gen2 compliance, the tag integrates seamlessly into existing UHF | RAIN – RFID infrastructures. It works reliably with fixed readers at instrument handover points, near-field antennas at surgical tray stations and mobile handheld scanners. There is no need to swap reader hardware or rework middleware – read-out works exactly as with any standard UHF tag.
