The Siemens 6GT2091-7UH10 is a flexible SIMATIC RF connecting cable designed to supply 5 V to a device from a USB port. It terminates in a USB-A connector on one end and a low-voltage 5.5-2.1 mm plug on the other, with a 1 m wire length and a cable sheath diameter of 3 mm. Two electrical cores carry the power.
The 1 m length is a standard reach for powering a reader or interface module mounted near a control cabinet's USB port — long enough to dress neatly, short enough to avoid coiling excess. The 3 mm sheath diameter and flexible cable construction suit routing through cable ducts or along DIN-rail assemblies without strain on the USB connector. The 5.5-2.1 mm low-voltage plug is a common barrel connector size for industrial RFID readers and small sensors; verify the mating jack on your device before committing the line.
