It carries four cores (4x AWG 22/19) in an unshielded PUR jacket, terminated at one end with an M12 4-pin female straight connector and at the other with labeled wire end sleeves for a screw-terminal block. The 5 m length covers the typical distance from a panel-mounted master out to a reader at a conveyor or portal station. Rated at 30 V maximum, which is the standard voltage ceiling for IO-Link device-level cabling — the cable itself isn't a power trunk, it's a signal and low-power supply line for the reader. The 5 m wire length is a practical constraint: if your layout needs a longer run between master and reader, you'll need a different cable or an extension strategy. The cable is unshielded, which is fine for the short, point-to-point IO-Link connection in a clean electrical environment, but if you're routing near VFD output cables or welding supplies, a shielded variant would be the better call. ## Deployment context This cable connects an IO-Link master (typically DIN-rail mounted inside a control panel) to an RFID reader mounted out on the line — think read points on conveyors, pallet ID stations, or tool identification portals. The M12 end locks with the standard knurled nut; the open end with wire end sleeves lands on a terminal block in the reader or junction box.","metaTitle":"Siemens 6GT2891-4LH50 SIMATIC RF IO-Link Connecting Cable, 5","metaDescription":"Siemens 6GT2891-4LH50 SIMATIC RF IO-Link connecting cable, 5m length, rated 30V, M12 4-pin female to open end with wire end sleeves.
