It terminates in an M12 male 12-pin straight connector on one side and is open on the other, with a braided shield of tin-plated copper wires for noise immunity in industrial RFID environments. Rated for a maximum of 42 V, the cable handles the DI/DO signals typical of reader I/O without exceeding the insulation system's limits. The 5 m length covers most reader-to-panel or reader-to-junction-box runs in a typical RFID gate or conveyor installation. ## Cable construction and environmental tolerance The cable sheath is black PUR (polyurethane), which gives it resistance to grease and mineral oil per DIN EN 60811-2-1 — a practical advantage in machining or fluid-handling zones where coolant and lubricant splash is routine. The jacket is also UV-resistant, so outdoor or sun-exposed mounting positions are acceptable. Fire behavior is flame-resistant per IEC 60332-1-2 and VW-1, and the cable is not halogen-free — the wire insulation is PVC. The cable is rated for 2 million bending cycles with a minimum bending radius of 85 mm under continuous flexing, and 42.5 mm for a single bend. This makes it suitable for cable-carrier or drag-chain routing on moving machine parts, not just static panel wiring. ## Electrical and signal integrity Each of the 12 cores is 0.14 mm², with a maximum loop resistance of 284 mΩ/m and an insulation resistance coefficient of 10 GΩ·m. The braided shield keeps coupled noise off the signal lines, which matters for reliable DI/DO communication in the electrically noisy environment around RFID readers and conveyors. The cable designation is LSPYwC11Y, with data wire insulation per DIN 47100 color coding. The symmetrical tolerance on the outer diameter is 0.2 mm, which means the cable passes cleanly through standard PG or metric cable glands without binding. Because this is a reader-specific cable assembly (not a generic sensor cable), there is no direct functional second-source that drops in without rewiring. The M12 12-pin male/open configuration is particular to the SIMATIC RF600 family. If you are sourcing against a BOM that calls out 6GT2891-0CH50, the cleanest path is to quote against the original order code rather than try to adapt a general-purpose cable.","metaTitle":"Siemens 6GT2891-0CH50 SIMATIC RF600 cable, 5 m, 12-core, M12","metaDescription":"Siemens 6GT2891-0CH50 SIMATIC RF600 DI/DO cable for RF650R/RF670R/RF68xR readers. 5 m, 12-core, shielded PUR, M12 male/open end.
