The Siemens 6GT2891-0FN20 is a preassembled PUR connector cable for the SIMATIC RF300 identification system. It links the ASM 456, RF170C, or RF180C communication modules to the reader head, or serves as an extension cable between the same modules and MOBY D/E/I/U or SIMATIC RF300/RF600 readers. The 20 m length covers long runs on conveyor lines or gantry tracks where the reader sits well away from the control cabinet.
What the PUR Jacket Means in the Pit
The PUR jacket shrugs off the abrasive slurry and oil mist common in mining and mill environments. It resists cutting and abrasion better than PVC, so this cable survives being dragged across sharp-edged cable trays or routed near crusher vibration. No IP rating is listed in the spec, but PUR is the standard choice for washdown and high-flex RFID applications in the SIMATIC RF300 family.
