NXP U8 Rugged ABS On-Metal RFID Screw Tag 135x21mm [U8-ABS-13521]

The NXP U8 Rugged ABS On-Metal RFID Screw Tag 135x21mm (Model: U8-ABS-13521) is a heavy-duty, impact-resistant industrial RAIN RFID transponder designed for harsh outdoor asset tracking, steel shipping containers, heavy construction machinery, railway rolling stock, oil and gas pipelines, and returnable transport packaging (RTP). Powered by the NXP UCODE 8 silicon IC, this tag features an internal microstrip resonant cavity encapsulated in an IP68 waterproof UV-stabilized ABS casing, delivering an outstanding read range of up to 8.0 to 12.0 meters directly on metal surfaces.

1. Extreme Industrial Encapsulation & RF Physics

Mounting standard RFID tags on metal surfaces causes RF cancellation. The U8-ABS-13521 incorporates an engineered internal dielectric cavity that leverages the metallic asset as an expansive RF ground plane. Operating across 860 MHz to 960 MHz (tuned for Indian WPC 865–867 MHz), NXP UCODE 8's -23 dBm sensitivity ensures high-velocity reading when trucks or forklifts pass through gate portals at speeds up to 25 km/h.

2. Screw Bolting & Extreme Environment Resistance

The rugged 135 mm × 21 mm × 12 mm ABS housing features two reinforced M4 screw/rivet holes (120mm hole spacing) for permanent mechanical bolting onto steel frames, chassis, or concrete beams. It withstands continuous outdoor exposure from -40°C to +85°C, mechanical crushing pressures, chemical washdowns, and UV solar degradation. Conforms to EPCglobal Gen2v2 and ISO/IEC 18000-63 with 128-bit EPC memory.
