IDTS-1804 UHF On-Metal PCB RFID Tag 18x4x3.5 mm for Tool Cribs, PCBs and Small Metal Assets

The IDTS-1804 is a passive UHF on-metal (anti-metal) RFID tag built on a PCB body and shaped as a small rectangular bar measuring just 18 x 4 x 3.5 mm. It is designed to be fixed directly onto metal, and its slim bar profile fits the narrow edges, brackets and housings where a conventional label or a larger hard tag simply will not sit. Two mounting holes, one at each end, allow it to be mechanically fixed to the asset, and the chip sits protected under a black epoxy blob at the centre of the board.

Applications

• Tool cribs and maintenance stores - identification of hand tools, small dies, cutters and spare parts that are issued and returned daily
• Electronics manufacturing - tagging PCBs, sub-assemblies and instrument housings as they move through the line, where the 18 x 4 mm footprint suits the space available on a board edge or chassis rail
• IT asset audits - marking network switches, rack accessories, docking stations and small metal enclosures for faster annual verification than barcode scanning allows
• Manufacturing WIP - small metal jigs, fixtures, mould inserts and gauges circulating between machines and inspection
• Utilities and process plants - valves, fittings, couplings and other small metal components inspected on a maintenance calendar
• Pharma and laboratory environments - small stainless equipment, trolley fittings and calibrated accessories that need traceable identity
• Elevated-temperature process stages - components that pass through curing, drying or paint-shop stages that remain inside the stated -20 C to +150 C range

Why Choose This Tag

• Genuinely small. At 18 x 4 x 3.5 mm it is one of the smallest on-metal formats we stock, opening up assets that are too narrow or too crowded for a standard anti-metal tag.
• Reads on metal. The anti-metal PCB construction is intended for direct mounting on metal, and delivers approx. 1 m on metal - useful working distance from a handheld for aisle-side or bench-side audits.
• Wide thermal window. The -20 C to +150 C operating temperature covers Indian ambient extremes as well as assets that see warm process stages.
• Fixed, not stuck. Two mounting holes, one at each end, allow mechanical fixing to the asset rather than relying on adhesive alone.
• Standards-based data. ISO18000-6C with 128-bit EPC and 96-bit TID means it works with the passive UHF handhelds and fixed readers already deployed across Indian warehouses, plants and IT estates.

Read range is a typical figure and will vary with the reader and antenna used, transmit power, the mounting surface and the surrounding environment. We recommend a sample trial on your own assets before bulk deployment.
