The Siemens 6GT2091-4LH20 is a pre-assembled SIMATIC RF MV plug-in cable designed to connect an RFID reader to the RF120C communication module. It carries a 300 V maximum rating and is built with a braided shield of tin-plated copper wires, making it suitable for industrial environments where signal integrity matters. The cable terminates in a Sub-D 9-pin male connector (angled at 45°) on one end and an M12 8-pin female straight connector on the other, which matches the interface layout on Siemens RF120C modules and compatible readers.
Rated for 300 V, the cable handles the signal-level voltages typical in RFID reader circuits without derating concerns. The UL/ETL listing confirms it meets North American safety standards for 300 V CM cable (cable only, not the assembled plugs). The cable jacket is grease-resistant and mineral-oil-resistant, which matters if the cable runs near lubricated machinery or hydraulic lines. It is also UV-resistant, so it holds up in outdoor or high-bay applications where sunlight exposure is a factor. Flame behavior meets IEC 60332-1-2, meaning the cable will not propagate flame along a horizontal run — a standard requirement for control cabinets and cable trays in most industrial installations.
The PUR trailing cable is rated for 3 million bending cycles with a minimum bend radius of 75 mm under continuous flexing, and a tighter 21.6 mm for single-bend installations. Maximum tensile load is 200 N, so it can handle the pull forces from cable carriers or drag chains in automated material-handling lines. Operating, storage, transport, and installation temperature range is a uniform -30 to +80 °C, which covers most factory-floor conditions including unheated warehouses and hot production zones near ovens or presses. The cable is silicon-free, a critical spec for applications where silicone outgassing can contaminate paint lines or sensitive optics. It is not halogen-free, so it is not the first choice for plenum-rated runs where low-smoke, zero-halogen cable is mandated.
This is a specialized pre-assembled cable for the SIMATIC RF product family, not a generic off-the-shelf cable. If you are replacing a failed cable on an existing RF120C installation, this is the direct OEM replacement — no adapter or field termination required.
