The Siemens 6GT2891-4JN10 is a pre-assembled SIMATIC RF MV plug-in cable, 10 m long, designed to connect an RFID reader to a communication module such as the ASM 456, RF160C, RF170C, or RF18XC. It is a 6-core cable with a braided shield of tin-plated copper wires, terminated with an M12 8-pin male straight connector on one end and an M12 8-pin female angled connector on the other. The PUR jacket and trailing-capable construction make it suited for dynamic applications on moving machine parts or cable carriers.
Rated for 3 million bending cycles with a minimum continuous-bend radius of 75 mm, this cable is built for high-flex applications like gantry robots or linear axes. The minimum single-bend radius is 21.6 mm, and the multiple-bend minimum is 43 mm — respect these during routing to avoid internal conductor fatigue. Maximum tensile load is 200 N, which sets the pull-force limit during installation or when the cable is dragged through a cable carrier. The cable is rated for operation, storage, transport, and installation across the full -30 to +80 °C range, so no special temperature derating is needed for typical factory-floor environments. It is resistant to grease, mineral oil, and UV radiation, and its flame behavior meets IEC 60332-1-2. The jacket is black PVC, silicon-free, but not halogen-free — note that for any low-smoke, zero-halogen (LSZH) zone requirements.
Electrical characteristics and approvals
Maximum rated voltage is 300 V. Loop resistance is specified at a maximum of 160 mΩ/m, and insulation resistance coefficient is 20 GΩ·m — both figures you'd use to verify signal integrity over the full 10 m run, especially for RS-485 or similar differential signals. The cable carries EAC approval for the Eurasian Economic Union customs zone. The wire insulation follows DIN 47100 color coding, and the outer diameter has a symmetrical tolerance of 0.2 mm, which matters for gland fit.
