It carries a 300 V maximum rating and is built for trailing applications with a 5 m length. The cable is terminated with three connectors: a Sub-D female 9-pin straight, an M12 female 8-pin straight, and an M12 male 4-pin straight, covering the reader and PC interface sides. The 300 V maximum rating (UL/ETL listed, CM cable only without plug) means this cable is suitable for signal-level circuits within that voltage ceiling — typical for RS232 communication lines, not power distribution. The CM (Communications Multipurpose) listing per UL 1581 confirms it meets flame-test requirements for cable trays and plenum-adjacent runs. Flame resistance per IEC 60332-1-2 means the cable will not propagate flame along its length in a vertical-tray fire scenario — a standard requirement for control panels and machine wiring in most industrial jurisdictions. The PUR sheath is resistant to grease and mineral oil, so it holds up in machine-tool environments or near hydraulic lines where PVC jackets soften. It is also silicon-free, which matters if the cable runs near paint or coating lines where silicone outgassing causes cratering. Rated for 3 million bending cycles with a continuous-bend radius of 75 mm, this cable is designed for cable carriers or robotic track applications where flex life is the limiting factor. The minimum single-bend radius of 21.6 mm gives you the tightest pull-through clearance for panel entry. ## Where this class of cable is used This cable belongs to the SIMATIC RF200/RF300 accessory family, used to connect RFID readers to a host PC or controller over RS232. Typical deployment is on conveyor lines, pallet-handling stations, or access gates where a read head is mounted on a moving axis and needs a flexible, oil-resistant umbilical. EAC approval is confirmed, covering customs clearance for shipments into Eurasian Economic Union member states. The UL/ETL listing at 300 V covers North American installations, though the CM rating applies to the cable only, not the assembled connectors. For BOM freeze or PCN watch, this part carries the WG classification per IEC 81346-2 and WGB per the 2019 revision — useful for asset-tagging schemes that follow that standard.","metaTitle":"SIMATIC RF200/RF300 Connecting Cable 6GT2891-4KH50, 5 m, 300","metaDescription":"SIMATIC RF200/RF300 pre-assembled connecting cable, 5 m, 300 V rated, RS232 reader to PC, PUR trailing cable, active lifecycle, UL/ETL listed.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RFID & Auto-ID"],"specifications":{"title":"6GT2891-4KH50","Maximum":"300 V","To Grease":"resistant","Wire Length":"5 m","description":"SIMATIC RF200/RF300 connecting cable, pre-assembled, between reader and PC (RS232), PUR, trailing, length 5 m 24 V-side w.
