The Siemens 6GT2803-0AB00 is a SIMATIC RF300 handheld terminal, model RF310M, built on a Psion WA Pro G2 platform. It integrates an RFID read/write unit for 13.56 MHz transponders supporting RF300-specific, ISO 15693, and ISO 18000-3 protocols, with a maximum transfer rate of 106 kbit/s. It runs Windows Embedded CE 5.0 and is programmable via.NET and C++ using the 'RFID reader interface' API. The VGA color touch screen (3.6 inch, 480 x 640 pixels) and alphanumeric keypad provide operator interaction, with acoustic feedback through built-in speakers. Rated for operation from -20 to +50 °C and storage from -40 to +60 °C, with IP54 protection — suitable for shop-floor use where dust and splash resistance matter, though not for washdown zones.
The listed MTBF of 55 years reflects a design intended for continuous industrial use; for a handheld device, that's a strong reliability indicator, though actual field life depends on battery cycle count and drop exposure. The integrated lithium-ion battery (3 A·h) provides a typical operating period of 8 hours per charge, with fast-charging capability. The battery is permanently installed and not customer-replaceable, so plan for unit-level swap when the battery degrades. Read range is 80 mm — that's the maximum working distance for reading/writing RF300 and ISO 15693 tags. It is not multitag-capable, so each read cycle handles one transponder at a time. The 1.5 m drop rating means it survives a fall onto concrete from typical waist height — important for handheld use on a production floor.
The handheld runs Windows Embedded CE 5.0, an older embedded OS. If your application requires a modern OS or cloud connectivity, factor that into your platform decision — this unit is a proven, field-hardened tool, not a future-proof compute platform.
The terminal communicates via a tether port with RS232 and USB 1.1, or through a docking station with a low-insertion-force (LIF) connection. The docking station also supports mains operation and charging. A WLAN module is available as an accessory for wireless operation. It is designed to work with Siemens RF300 and RF200 series transponders, as well as MOBY D and ISO 15693 tags. The pre-installed RF310M.exe software handles execution of these transponder protocols out of the box. Dimensions are 92 mm wide, 265 mm high, and 42 mm deep — a pistol-grip form factor typical for handheld readers.
