Ø20 mm FR4 on-metal construction
The circular FR4 (PCB) body is designed for direct use on metal. Two 2 mm mounting holes are specified.
RX-D20 RFID Anti-Metal Tag
Ø20 mm circular UHF on-metal tag | Alien Higgs-3 and IP68
Compact FR4 identification for metal assets with power- and band-specific reference performance
Up to 3.2 m with a 4 W fixed reader
Documented metal-surface reference distances are 3.2 m in the US band and 2.8 m in the EU band with a 4 W fixed reader. Actual range depends on the reader, orientation, mounting and environment.
Handheld reference distances stated separately
With the documented 2 W handheld reader, the metal-surface reference distances are 2.4 m in the US band and 2.3 m in the EU band; these values are not interchangeable with the fixed-reader results.
IP68 with a wide specified temperature range
The specification lists IP68, operation from -40°C to +100°C and storage from -40°C to +150°C.
