IoTRHA RHA-500-RC04 UHF RFID Reader & Writer 4- 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. Four-Channel reader&writer Module Introduction:

The IoTRHA RHA-500-RC04 UHF RFID reader & writer 4-channel module is designed based on the high-performance UHF-specific RF chip, Impinj R2000. Utilizing Impinj's dynamic Q algorithm and constructed data model, we have independently developed the "Adaptive Dynamic Q Anti-collision Algorithm V3.0" and integrated it into all our self-developed UHF RFID reader & writer module products. Compared to similar modules on the market, our modules, which adopt Impinj's dynamic Q algorithm, demonstrate significantly improved multi-tag reading performance, with the differences becoming more pronounced as the number of tags increases. The module features 4 RF SMA antenna connection ports, allowing simultaneous connection to 4 antennas for real-time cyclic inventory. The module's output power range is 0~33dBm, and it offers a considerable tag reading distance, with a stable identification range of over 20 meters using a 9dBi circularly polarized antenna and over 30 meters with a 12dBi circularly polarized antenna.

The IoTRHA RHA-500-RC04 UHF RFID reader & writer module series is suitable for applications requiring antenna identification and reading, such as access control channels, smart cabinets, high-quality consumables cabinets, tool cabinets, apparel passage machines, and archive cabinets.
