What it is and what it does
The 6GT2891-4KH50-0AX1 is a SIMATIC RF200/RF300 pre-assembled connecting cable, designed as a plug-in cable for connecting an RS 232 reader to a PC. It is a highly flexible communication line with 6 cores, 5 m length, and carries a braided shield made of tin-plated copper wires.
Key ratings and what they mean for fit
Rated for a maximum of 300 V, this cable is suited for the control voltage levels typical in industrial RS232 reader connections — not for power distribution. The PUR jacket is resistant to grease and mineral oil, and the cable is silicone-free — relevant for food-and-bev or lubricated environments where standard PVC jackets would degrade. Flame-resistant per IEC 60332-1-2, so it passes vertical-wire flame tests for control cabinets and cable trays. Rated for 3 million bending cycles with a minimum continuous bend radius of 75 mm, meaning it survives continuous flexing in cable-track or robot-dress-pack applications. The 9-pin submin-D (female, straight) on the PC end and M12 (female, 8-pin, tilted) plus M8 (male, 3-pin, straight) on the reader end mean you plug directly into standard SIMATIC RF200/RF300 reader ports without field-wiring a connector.
Where it is used
This cable connects an RS 232 reader to a PC in RFID identification systems — typical for SIMATIC RF200/RF300 readers on conveyor lines, access gates, or pallet-ID stations.
Sourcing and lifecycle
Approved with EAC and UL/ETL listing for 300 V (CM rated for the cable only, not the pre-assembled plugs), so it clears customs into EAEU and North American markets without additional certification paperwork.
