The Siemens 6GT2091-4LN10 is a pre-assembled SIMATIC RF MV plug-in cable, purpose-built to connect an RFID reader to the RF120C communication module. It's a 6-core, shielded, trailing cable, 10 m long, terminated on one end with a Sub-D male 9-pin connector (45° angled) and on the other with an M12 female 8-pin straight connector. The cable designation is L-YC11Y 6x1x0.25 6x24AWG CM, and it's rated for 300 V maximum.
The 300 V rating covers the signal and power levels typical on an RFID reader link — no issue for standard 24 VDC sensor supplies, and gives headroom for longer cable runs where voltage drop is a concern. The PUR jacket is resistant to grease and mineral oil, and the braided shield of tin-plated copper keeps RF noise from the reader signal out of the rest of the cabinet. The cable is rated for 3 million bending cycles with a continuous bend radius of 75 mm, which means it's built for moving applications like robot arms or linear slides, not just static tray runs. If you're pulling it through a cable carrier, the minimum single-bend radius is 21.6 mm and multiple-bend minimum is 43 mm — stay above those and the shield integrity holds.
Regulatory and environmental fit
The cable carries EAC approval for Eurasian markets, and the bare cable (without plug) has a UL/ETL listing at 300 V with a CM (Communications) rating, which covers North American plenum and riser installations. The jacket is halogen-free? No — it's PVC (: Halogen-Free: No). It is silicon-free, which matters in paint-shop or adhesive-bonding environments where silicone outgassing can cause adhesion failures. Fire behavior is flame resistant per IEC 60332-1-2, so it passes the vertical flame test for single cables. UV radiation resistant for outdoor exposure, though the black sheath and PUR material already handle that. Temperature range is -30 to +80 °C across storage, transport, operation, and installation — a wide enough window for unheated warehouses or machine-side use.
