It's the plug-in link between the antenna and the controller interface in an RFID identification system. The cable is coiled, giving a working length that stretches from 1.6 m to 4 m, with a total cable length of 5 m. That 1:4 elongation ratio means it retracts when not under tension, keeping the line side tidy. Rated for a maximum of 300 V, this is a signal-level cable — not a power feed. The braided shield of tin-plated copper wires keeps RF noise out of the communication line, which matters when the cable runs alongside motor drives or contactors in the panel. ## Connector and Wiring Detail One end terminates in an M12 male, 8-pin, straight connector; the other end is an RJ-50. That RJ-50 is a 10-position modular plug, not the standard 8-position RJ-45 — verify the communication module's port accepts RJ-50 before wiring. The cable carries 4 electrical cores plus data wires with insulation per DIN 47100. Wire insulation is TPE-E, which holds up to flexing in the spiral. Tensile load is limited to 5.6 N maximum — don't use this as a strain relief or pull cord.","metaTitle":"Siemens 6GT2191-0BH50 SIMATIC RF MV Plug-in Cable, 300 V, 4","metaDescription":"Siemens 6GT2191-0BH50 SIMATIC RF MV plug-in spiral cable, 300 V max, 4 m working length.
