Impinj Speedway Revolution R420 4-Port Fixed RAIN RFID Reader
The Impinj Speedway Revolution R420 4-Port Fixed RAIN RFID Reader is an enterprise-class fixed RFID reader designed for warehouse management, manufacturing, logistics, retail, inventory control and asset-tracking applications. Its four external antenna ports allow multiple reading zones, entry points or production areas to be managed through one reader.
Impinj Autopilot technology automatically analyses the surrounding RF environment and helps optimise reading performance in the presence of interference and RF noise. Ethernet, Power over Ethernet, GPIO, LLRP, Speedway Connect and Octane SDK support enable integration with ERP, WMS, MES, automation and enterprise asset-tracking systems.

Frequently Asked Questions
How many antennas does the Impinj Speedway R420 support?
The R420 includes four direct external RFID antenna ports. Antennas and RF cables may be supplied separately depending on the selected package.
Is the Speedway R420 a portable RFID reader?
No. The R420 is designed for fixed installation on walls, cabinets, shelves, production lines or dock-door reading points.
Which RFID tags can the R420 read?
It supports passive RAIN UHF RFID tags compatible with EPC Class 1 Gen 2 and ISO/IEC 18000-6C. Tag selection should be based on the application surface and environmental conditions.
Can the Impinj R420 operate through PoE?
Yes. Power and data can be supplied through IEEE 802.3af-compatible PoE infrastructure. A compatible external power supply may also be used.
What is the RFID reading distance?
A fixed reading distance cannot be guaranteed. Performance depends on the RFID tag, antenna, RF cable, output power, mounting method, tracked material and surrounding RF conditions.
