Product Description:
The ZK7A26-3031-0018 motor cable from Beckhoff is a durable and high performance cable designed for industrial automation applications. This cable is suitable for power and Ethernet transmission.
This motor cable has a voltage capacity of up to 1000 V AC with mutual capacitance between Ethernet wires at 55 nF/km. It supports both Ethernet and power transmission with a conductor cross section for power at 3 x 2.5 mm² + 2 x 1.5 mm² and for Ethernet at 1 x 4 x 0.34 mm². It is designed with shielding on Ethernet conductors that provide effective attenuation of over 40 dB across a range of 30 to 100 MHz which is critical for minimizing interference. The cable's resistance levels such as 8.3 Ω/km for power conductors and 58.0 Ω/km for Ethernet enhance its capability to reduce power loss and maintain data integrity over long distances. The motor cable's design includes materials such as tinned copper for power conductors and bare copper for Ethernet all enclosed in a black TPU (UL 94 HB) jacket.
The ZK7A26-3031-0018 motor cable cable has an outer diameter of 11.9 mm with a weight of 210 kg/km. The motor cable has a minimum bending radius of 7 times the outer cable diameter when moved and 4 times when installed in a fixed position. Its insulation resistance exceeds 500 MΩ * km. It provides excellent durability with a dielectric strength of 4 kV for both power and Ethernet components. The cable can handle acceleration up to 30 m/s² and is suited for drag chain applications. The cable’s robust shielding with a covering factor of over 85 % guarantees reliable Ethernet performance under various conditions.
