The Siemens 6GT2831-6AA50 is a SIMATIC RF1000 series access control reader, model RF1060R, designed to read HF RFID transponders at 13.56 MHz. It handles ISO 15693 and ISO 14443 A/B tags, plus Felica, NXP NTAG21x, and HID iClass protocols, making it suitable for personnel access, tool tracking, or work-in-process identification on a production line. It connects to a PC or control system via a fixed 1.8 m USB 2.0 Type A cable, drawing power from the USB port — 0.15 A typical, 0.3 A max at 5 V. No external supply needed.
The reader is panel-mount only — four M4 screws through the cabinet door. The front face is IP65, so it handles washdown and dust ingress on the operator side; the rear connections are inside the enclosure. Dimensions are 90 mm wide, 62 mm high, 23.5 mm deep, in a Ti gray PC-GF housing. Shock resistance per EN 60721-3-7 Class 7M2 (300 m/s²) and vibration at 50 m/s² — it survives on a machine frame or conveyor line, not just a climate-controlled office.
Read performance and multi-tag handling
Maximum read range is 30 mm, but this depends on the transponder type — check Siemens support document 67384964 for your specific tag. The reader is multi-tag capable and supports a maximum transfer rate of 424 kbit/s over the air interface. A three-color LED on the front gives visual status feedback. The unit is silicon-free, which matters for some paint-shop or potting applications.
