The Siemens 6GT2803-1BA10 is a SIMATIC RF300 handheld terminal, model RF350M, built around a Nordic ID Merlin base unit with an integrated RFID write/read head and preloaded user software. It operates at 13.56 MHz and supports RF300-specific, ISO 15693, ISO 18000-3, and ISO 14443 protocols, with a maximum transfer rate of 106 kbit/s. The terminal is suited for reading and writing RF300, MDS E6xx, and ISO 15693 transponders, especially smaller tags, and can work with external antennas (ANT 3, 3S, 8, 12, 18, 30) to extend its 80 mm range.
The 3.5-inch QVGA color touch display (240 x 320 pixels) with alphanumeric keypad and speakers gives the operator a full interface for data entry and feedback on the factory floor. IP54 protection means the unit is dust-protected and splash-resistant — suitable for use in industrial environments where light moisture or dust is present, but not for washdown zones. A typical battery life of 8 hours on the standard 2.6 Ah Li-ion pack (fast-charging capable, 7.4 V) supports a full shift of mobile operation; the battery is customer-replaceable via the charging/docking station. The unit can survive a drop from up to 1.2 m, which is realistic for handheld use on a production line or in a warehouse.
This is a mobile terminal — it does not mount on a DIN rail or in a panel. It communicates via WLAN, USB, and Ethernet through the charging/docking station, so the station must be wired to the plant network. Pre-installed Windows Embedded CE 6.0 provides a familiar OS environment for custom application development, with 256 MiB of RAM and 288 MiB of data/program memory.
