The Siemens 6GT2891-0FH50 is a preassembled connection cable for the SIMATIC RF300 and RF600 RFID systems. It runs between the ASM 456 communication module, the RF170C or RF180C reader, and the antenna, or serves as an extension cable between those modules. Length is 5 m. This cable lives in the Wire and Cable category under Quick Disconnect Cables & Cord Sets. It's a factory-terminated assembly, not a field-cut-to-length piece — order the exact length you need.
The cable is designed for the SIMATIC RF300/RF600 ecosystem. It connects ASM 456, RF170C, and RF180C modules to readers or extends the link between them. If your panel uses MOBY D, E, I, or U legacy readers, this cable also works with those via the same interface.
