The Siemens 6GT2801-1BA10-0AX1 is a SIMATIC RF310R (GEN2) RFID reader operating at 13.56 MHz with an integrated antenna and RS422 interface using the 3964R protocol. It reads RF300-specific, ISO 15693, ISO 18000-3, and ISO 14443 transponders, with a maximum read range of 60 mm — though actual range depends on the specific transponder type (see Siemens support entry 67384964 for the per-transponder values).
Rated IP67, so the housing and the M12 connector seal hold up in washdown zones and dusty environments — the sealing washer at the connector face is the wet-end barrier, not the housing threads. The PA 12 housing handles the thermal cycling and is silicon-free, which matters if this sits near paint or bonding lines. Mounting is via four M5 screws — no DIN-rail clip, so plan for direct panel or bracket mounting. The 55 x 75 x 30 mm footprint is compact enough for tight machine-mount positions.
Electrical and communication interface
The M12 8-pin connector carries both power and the RS422 communication lines. The RS422 interface supports cable runs up to 1000 m, with a maximum transfer rate of 106 kbit/s over the radio link. Typical read and write access per byte is 0.13 ms. A 5-color LED on the housing gives visual status feedback — useful for on-site troubleshooting without needing a handheld terminal.
