The Siemens 6GT2391-0AH30 is a pre-terminated coaxial cable assembly for the SIMATIC RF200 and RF300 RFID systems. It connects a short-range HF antenna (ANT 3, 3S, 8, 12, 18, or 30) to the reader via M8 plug connectors — one straight, one angled. The 3 m fixed length and 50 Ω impedance match the RF front-end of the reader, so no field termination or impedance tuning is needed.
Rated for 300 V maximum (UL style 1581, Sec. 1090 H), which covers the signal levels on the reader-to-antenna link with margin — the cable is not a power feeder, but the rating confirms it can share a cable tray with 300 V control circuits without derating. The 50 Ω characteristic impedance is the standard for the RF200/RF300 antenna port; a mismatch here would degrade read range and cause reflections. The braided shield of tin-plated copper wires keeps radiated emissions from the reader's carrier signal inside the cable, which matters when the cable runs alongside other fieldbus or sensor lines in the same trunk. The PUR jacket is halogen-free and silicon-free, so it won't outgas contaminants in clean-room or coated-panel environments. Flame resistance to IEC 60332-1-2 means it self-extinguishes — a requirement for vertical cable runs inside control cabinets or cable ducts. The cable is also rated for continuous flexing (75 mm bend radius, 3 million cycles), so it survives on a robot arm or a moving gantry without fatigue failure.
Where this cable is used
This cable is the link between the SIMATIC RF200/RF300 reader and the remote antenna in an RFID read station. Typical deployment is on a conveyor line, a pallet-transfer station, or an AGV docking point where the antenna is mounted close to the tag path and the reader is in a panel 3 m away. The M8 connectors are IP67-rated by design (the reader and antenna ports are sealed), so the cable can run through washdown zones or dusty environments without a secondary conduit.
