Product Description:
The ZK1090-9191-0020 is an Ethernet motor cable manufactured by Beckhoff as part of the ZK Motor Cables series. It is supplied with RJ45 plug-to-RJ45 plug connectors, both male, in an 8-pin form factor for direct connection between drives, I/O stations, and control PCs. The cable groups the signal pairs inside a dedicated jacket so high-speed fieldbus data can pass through machinery without requiring a bulky cable assembly. Because both ends use the same connector style, it can be connected quickly in systems that already use RJ45-based network ports. Its compact build also helps when routing lines through crowded control cabinets or other spaces with limited clearance.
The cable length of 2.00 m supports short in-cabinet runs that help reduce attenuation over the link. The short reach also reduces unused slack, which can simplify cable management around switches, couplers, and drive terminals. Internally, the twisted-pair arrangement of 4 x 2 x AWG26 separates four differential channels, which helps limit crosstalk at the cable's rated voltage of 60 V. Each molded connector is rated for 1 A at 50 °C, and the plug dielectric can withstand 160 V for added electrical margin. A flexible outer sheath made of PUR (polyurethane) resists oils and continuous motion, making the cable suitable for repeated flexing where guided movement is required.
The copper conductors have a cross-section of 0.14 mm² (AWG26), and the loop resistance is 280 Ω/km, which helps keep voltage drop low over the stated length. Pair shielding with an overall braid provides 90% coverage, and the mutual capacitance of 51 pF/m at 1 kHz supports stable signal transmission across the twisted pairs. Propagation delay is 5.08 ns/m, which fits timing demands commonly associated with EtherCAT communication. Polyethylene insulation and an IP20 protection rating make the assembly suitable for dry, electrically protected enclosures. This combination of conductor size, shielding, and insulation supports reliable data transfer in enclosed machine installations.
