The SRK-MU03 UHF RFID Integrated Reader is a compact and efficient RFID solution designed for access control, asset identification, inventory management, and industrial automation applications. With a built-in 8dBi circularly polarized antenna and a reading distance of up to 3 meters, the SRK-MU03 enables contactless identification of RFID tags across a controlled reading zone.

Operating in the 865–868 MHz UHF frequency band, the SRK-MU03 supports ISO 18000-6C / EPC Gen2 protocols, making it suitable for compatible UHF RFID cards and tags. Its multi-tag reading capability supports more than 50 tags, helping improve identification efficiency in applications where multiple tagged items need to be detected.

The reader features adjustable RF power from 0–30dBm, allowing the output power to be configured according to application requirements. It supports automatic, trigger, and interactive operating modes, providing flexibility for different RFID workflows.

For system integration, the SRK-MU03 supports RS485, Wiegand 26/34, and optional RJ45 Ethernet and Wi-Fi connectivity. Additional optional interfaces may include GPRS, relay, trigger I/O, and USB, depending on the configuration.

Designed for practical installation, the SRK-MU03 features a compact housing measuring 160 × 130 × 21 mm. Its low-power operation, identification buzzer or LED indicators, and operating temperature range of -20°C to +70°C make it suitable for various indoor and industrial environments.
