UHF RFID Reader AL6909A, Long Range 0–18m, Supports ISO18000-6C, RS232 / RS485 / Wiegand / Trigger + WiFi, etc. Used for Vehicle Weighing, Gate Access Control, and Warehouse Management

Product Overview

The AL6909A Long-Range UHF RFID Reader/Writer is a high-performance device developed with the TM200 chip, supporting the ISO18000-6C (EPC Gen2) standard protocol. It comes with a built-in 9dBi Circular Polarized Antenna, delivering a maximum read range of up to 18 meters. The device is engineered for durability with an IP65-rated dustproof and waterproof housing. It supports both FCC and CE frequency bands (software-configurable), making it ideal for outdoor and industrial environments that demand high accuracy and reliability.
