Product Description:
The ZK1090-9191-0050 is a network-grade cable produced by Beckhoff as part of the ZK Motor Cables series. In automated machinery, it links controllers, I/O stations, and motor assemblies, carrying low-voltage supply and Ethernet-based diagnostic data through a single jacket so that motion components stay synchronized with central control software. Its combined power-and-data layout reduces the need for separate cable runs between cabinet components and axis hardware. This helps keep routing compact where drives, I/O modules, and controllers are installed close together.
This model is delivered in a fixed length of 5.00 m and follows the Cat.5 performance class, a pairing that limits attenuation and crosstalk over the stated run. Internally, the cable contains a 4 × 2 × AWG26 construction. Each stranded pair has a conductor cross-section of 0.14 mm², and overall braid-and-foil shielding provides 90 % coverage for electromagnetic immunity. The outer sheath has an IP20 rating, which suits routing inside closed control cabinets. Electrically, the copper paths may carry up to 1 A at 50 °C, while the insulation system allows a continuous 60 V cable voltage. An RJ45 plug with 8 contacts terminates the assembly, and the connector insulation is matched to the stated interface voltage so the contact area can handle the potential present on hybrid drives without arcing.
Signal integrity is reinforced by a dielectric strength of 1500 V DC between each core and the overall shield, which helps protect electronics during hipot testing or transient events. Propagation delay is limited to 5.08 ns/m, so timing skew across the full 5 m remains minimal for deterministic fieldbus cycles. A loop resistance of 280 Ω/km indicates the expected voltage drop at maximum current, while low mutual capacitance of 51 pF/m and unbalanced capacitance of 1600 pF/km help preserve differential signal shape. The plug's rated potential of 160 V matches the insulation level used across the full assembly.
