The Siemens 6GT2831-6BA50-0AX0 is the RF1070R OEM variant of the SIMATIC RF1000 access control reader family — a compact, panel-mount RFID reader with integrated antenna, designed for physical access control at doors, gates, or enclosures where the front face sees the user and the electronics live behind the panel. It reads at 13.56 MHz and supports Legic Prime, Legic Advant, ISO 15693, ISO 14443 A/B (Mifare), Felica, NXP NTAG21x, and HID iClass transponders — covering most common credential formats in Europe and North America. The front face is rated IP65, so it withstands rain splash and washdown in outdoor or industrial entrance applications; the reader body is silicon-free, important for coating and potting processes in OEM integration.
Interfaces and integration
Two interface options on the 1.8 m pigtail: USB 2.0 Type A or RS232 — choose the USB variant for direct connection to a PC or industrial panel, or the RS232 line for legacy control systems or longer cable runs without USB distance limits. Power is drawn from the 5 V supply on the USB bus or an external 5 V DC source. Typical draw is 0.15 A at 5 V, maximum 0.3 A — well within the budget of a standard USB 2.0 port (0.5 A). Mounts with four M4 screws through the cabinet face; the 90 mm x 62 mm front plate and 23.5 mm depth behind the panel leave room in most standard junction boxes or enclosure cutouts.
Rated for operation, storage, and transport from -25 °C to +55 °C — suitable for unheated entrance vestibules or outdoor enclosures in moderate climates. Shock resistance per EN 60721-3-7 Class 7M2 (300 m/s²) and vibration at 50 m/s² means it survives door impacts and nearby machinery vibration.
Sourcing takeaway
This is a specified OEM variant — the front foil is blank (neutral, no company logo), so you either print your own overlay or integrate it into a custom fascia. The accessory kit includes a card holder, USB cable, and RS-232 connection line. If you are replacing a legacy reader or cross-referencing a different brand, the key fit parameters are: 13.56 MHz operating frequency, ISO 14443 A/B + Legic + HID iClass protocol support, USB or RS232 host interface, and the 90 x 62 mm front cutout with M4 screw fixing.
