IoTRHA RHA-500-RC032 UHF RFID Reader & Writer 32-Channel Module

Overview:

The IoTRHA UHF RFID reader&writer module series includes single/4/8/16/32 channels. These products are designed based on the high-performance Impinj R2000 UHF RFID chip. Utilizing the dynamic Q algorithm from Impinj and our independently developed "Adaptive Dynamic Q Anti-Collision Algorithm V3.0," we have significantly improved multi-tag reading performance. The more tags, the more evident the improvement. The module offers an output power range of 0-33dBm, with a stable reading distance of over 20 meters using a 9dBi circularly polarized antenna and over 30 meters with a 12dBi circularly polarized antenna. The IoTRHA UHF RFID reader&writer module series can be applied to UHF handheld devices, integrated machines, access control channels, smart cabinets, high-quality consumable cabinets, tool cabinets, clothing channels, archive cabinets, and other applications requiring antenna identification and reading.

1. 32-Channel reader&writer Module Introduction:

The IoTRHA RHA-500-RC032 is a UHF RFID reader & writer module designed with the high-performance UHF dedicated RF chip, Impinj R2000. Utilizing the dynamic Q algorithm and data model constructed by the American company Impinj, it incorporates our proprietary “Adaptive Dynamic Q Anti-collision Algorithm V3.0”. This algorithm is applied to all our UHF RFID reader & writer modules, significantly improving multi-tag reading performance compared to similar market modules. The module supports 32 RF SMA antenna ports, enabling the connection of up to 32 antennas for real-time inventory. The module's output power ranges from 0 to 33dBm, with a long reading distance: stable identification at over 20 meters with a 9dBi circularly polarized antenna and over 30 meters with a 12dBi circularly polarized antenna.

The IoTRHA RHA-500-RC032 UHF RFID reader & writer module series is suitable for various applications requiring antenna identification and reading, such as access control channels, smart cabinets, high-quality consumable cabinets, tool cabinets, apparel channel machines, and file cabinets.
