Cable for IO-Link Device Connection
The Siemens 6GT2891-4LH50-0AX0 is a pre-assembled SIMATIC RF IO-Link connecting cable, purpose-built for linking an IO-Link master to an IO-Link reader or sensor. It runs 5 m between the M12 4-pin female connector and the open-ended wire end sleeves, which are labeled for quick identification. Rated for a maximum of 30 V, this cable handles the typical IO-Link supply and data voltage without margin for higher-voltage applications. The 3-core, unshielded design with PVC insulation keeps the cable flexible for routing inside control cabinets or along machine frames.
Flame Resistance and Compliance
The cable carries multiple flame-resistance certifications: it is flame resistant according to DIN VDE 0482-332-1-2 / EN 60332-1-2 / IEC 60332-1-2, plus UL VW-1 and CSA FT1. It also complies with UL Std. 758 (AWM) Style 2464 and CSA Std. C22.2 No. 210 - AWM I/II A/B, which are the common benchmarks for tray-cable and appliance-wiring applications in North American panels.
Physical and Environmental Limits
Operating temperature range is -10 to +80 °C, with storage and transport extending from -40 to +80 °C. The minimum bend radius is 35 mm for a single bend and 69 mm for multiple bends — tight enough for most panel routing but requires attention in confined spaces. The cable is halogen-free? No — the insulation is PVC, which is not halogen-free. For installations requiring low-smoke zero-halogen (LSZH) materials, a different cable type would be needed.
