The Siemens 6GT2801-3AB10 is a SIMATIC RF300 RF380R RFID reader with an integrated antenna, operating at 13.56 MHz and supporting both RF300-specific and ISO 15693 transponders (MDS Dxxx series). It connects to communication modules and PC systems via an RS422 or RS232 interface using the 3964R protocol. The IP67 rating means the reader body and antenna withstand washdown environments — suitable for food-and-bev lines or outdoor deployment where dust and water jets are present. Read range is specified at 200 mm maximum, though this is dependent on the transponder type and adjustable via transmission power. For a given transponder, consult the Siemens support documentation (reference 67384964) to confirm actual range. Read and write access per byte is typically 0.13 ms, with a maximum transfer rate of 106 kbit/s over the radio link.
The reader measures 160 mm deep by 80 mm wide by 41 mm high, in anthracite PA 12 housing. It fastens with four M5 screws — no DIN-rail clip, so plan for direct panel or bracket mounting. Electrical connection is via an M12 8-pin connector, supporting RS422 up to 1000 m cable length or RS232 up to 30 m. Power is 24 VDC nominal (20.4 to 28.8 V range), drawing 0.16 A typical at 24 V. Shock resistance is per EN 60721-3-7 Class 7 M2 at 500 m/s², vibrational acceleration at 200 m/s². The reader is silicon-free, which matters for paint-shop or potting applications where silicone contamination is a concern.
