It connects an ASM 475 communication module to a reader, or serves as the 24 V power cable for RF61xR, RF650R, and RF68xR readers. The braided shield made of tin-plated copper wires keeps common-mode noise off the data pair in an industrial RF environment. ## Cable construction and mechanicals Designation is L-YC11Y 6x1x0.25 (6x24 AWG CM). Six cores, each 0.25 mm², with PVC insulation per DIN 47100. The sheath is black PUR, halogen-free is not claimed, but it is silicon-free and resistant to grease and mineral oil. Rated for 3 million bending cycles with a 75 mm bend radius under continuous flexing. Minimum single-bend radius is 21.6 mm; for multiple bends stay above 43 mm. Maximum tensile load is 200 N. This is a trailing cable — it is built for cable carriers on moving reader gantries or robot arms, not just a static panel drop. Loop resistance is 160 mΩ/m maximum, and the insulation resistance coefficient is 20 GΩ·m. The symmetrical tolerance on the outer diameter is 0.2 mm, which matters if you are feeding it through a tight grommet or a drag-chain guide. ## Environmental and approvals Operating, storage, transport, and installation temperature range is -30 to +80 °C across the board — no derating needed between handling and running. Flame resistant per IEC 60332-1-2. Resistant to UV radiation. EAC approved for the Eurasian market. UL/ETL listed for 300 V, but only on the cable without the plug — the M12 connector assembly is not part of that UL listing. The lifecycle status is active, so this is a current-production part, not a phase-out or last-time-buy. ## Termination and integration One end is an M12 female 8-pin straight connector; the other end is bare wires with wire-end ferrules and labeled. That means you land the bare end inside the ASM 475 or the reader's power terminal block, and the M12 end plugs directly into the mating port on the RF reader. No special tooling beyond a ferrule crimper.","metaTitle":"Siemens 6GT2891-4EH20 SIMATIC RF MV Plug-in Cable, 2m, 300V","metaDescription":"SIMATIC RF MV plug-in cable, 2m, 300V, PUR, trailing, braided shield.
