The Siemens 6GT2891-0KH50 is a preassembled connection cable for the SIMATIC RF300 RFID system. It runs between an RF380R read/write device and a PC with an RS232 serial port, using a PUR jacket for the 5 m length.
Where this cable fits
This cable belongs in the SIMATIC RF300 family, which is Siemens' RFID identification system for industrial production and logistics. The RF380R reader sits on the machine or conveyor side; the PC runs the identification software. The preassembled PUR cable saves field-termination time and keeps the RS232 signal path intact over the full 5 m run.
