EMH-series
Outdoor IoT RAIN RFID reader with Ethernet, USB, and Wi-Fi
The Identix EM300H is a compact and robust IoT RAIN RFID reader designed for outdoor applications, vehicle control, and demanding environments. It features a dual linear polarization internal antenna with 7 dBi gain and two additional SMA ports for external antennas, providing high performance and flexibility where reliability is essential.
With an IP67 protection rating, it is ideal for outdoor use, capable of withstanding dust, moisture, and severe weather conditions. Its interfaces include Ethernet PoE, Wi-Fi (802.11n 2.4 GHz), Bluetooth BLE 5.0, and USB, ensuring broad compatibility with various networks and systems.
Compatible with protocols such as MQTT and HTTP, the EM300H enables efficient integration with corporate systems. It also supports offline operation with an internal 8MB buffer, storing local readings during network failures, with subsequent automatic synchronization.
Supports automatic decoding of the main GS1 TDS standards, including SGTIN, SSCC, GRAI, and GIAI, enabling direct extraction of identifiers and their conversion into readable formats such as EAN-13 or custom strings.
Equipped with intelligent data filtering algorithms, the EM300H is ideal for applications such as vehicle access control, gatehouses, logistics yards, and fleet management, ensuring fast, accurate, and reliable reading of UHF RAIN RFID tags in demanding environments.
