What it is and what it does
The Siemens 6GT2823-0AA00 is a SIMATIC RF200 handheld reader — the RF210M model — with an integrated RFID write/read unit (RF210R) inside the same housing. It operates at 13.56 MHz and communicates via an RS422 interface through a permanently attached M12 8-pole connector on a spiral cable that extends from 2 m to 3.5 m usable length. The read range is 0 to 20 mm, and it is designed for RF200 / ISO 15693 transponders. Power is supplied at 24 V through the communication module — there is no separate power input on the handheld itself. The 3-color LED display gives operator feedback without needing to look at a screen. Programming is done via function blocks FB 45/55 and an ident profile, so it integrates into a SIMATIC controller environment using standard TIA Portal blocks.
Where it fits on the line
This is a handheld reader, not a fixed-mount tunnel gate. It is suited for manual scan stations, tool crib check-out, work-in-progress tracking on a cart, or any point where an operator brings the reader to the tag. The IP54 rating means it handles dust and splashing water — fine for a dry assembly line or a warehouse floor, but not for washdown zones. The spiral cable keeps the reader tethered to the control cabinet or a wall-mounted junction box; the M12 connector is the standard 8-pole pinout for RS422, so it mates directly to a SIMATIC RF120C communication module or equivalent. The 26 mm depth and 195 mm × 140 mm footprint are the reader body dimensions — the spiral cable adds reach but no panel-space demand. Mount the communication module on a DIN rail inside the enclosure; the reader lives on the outside, connected by the cable. The maximum drop height of 1.5 m gives some floor-impact tolerance if the operator drops it, but it is not a shock-rated industrial tool.
Key ratings and what they mean for fit
The 0–20 mm read range is the working distance from the reader face to the transponder. That is a short-range, high-reliability zone — the operator must bring the reader within 20 mm of the tag. It is not a walk-by portal. The 13.56 MHz HF band gives good performance around metal and liquids compared to UHF, which matters if the tagged item is a metal pallet or a liquid container. The maximum transfer rate of 26.5 kbit/s is the raw air-interface speed for ISO 15693 and ISO 18000-3 protocols. That is sufficient for reading a single tag UID plus a few data bytes per scan — typical for part-ID or tool-tracking applications. The reader is not multitag-capable, so it reads one tag at a time; do not plan it for bulk pallet reads. Operating temperature range is -20 to +50 °C; storage range is -25 to +60 °C. That covers most indoor factory environments but not freezer applications below -20 °C or hot outdoor storage above +60 °C.
