ZB9020
by Beckhoff
The Beckhoff ZB9020 from the ZS Motion Accessories series by Beckhoff is an industrial-grade EtherCAT cable designed for reliable data transmission in automation systems. Boasting an operating voltage of 600 V with a maximum peak of 125 V, this cable ensures safe performance without high-voltage application. With a minimum insulation resistance of 500 MΩ/km, it effectively prevents leakage currents and protects against electrical failures. Its primary function is to carry high-speed EtherCAT signals in harsh industrial environments, making it essential for precision communication.
This cable’s technical construction delivers exceptional signal integrity. The 100 Ω characteristic impedance (±15 Ω at 100 MHz) allows impedance matching in Ethernet networks, while its 250 Ω/km differential impedance ensures minimal reflection and stable differential signaling. Mutual capacitance is set at 52 nF/km and capacitance to ground at 1 600 pF/km, unbalanced, optimizing the cable for long-distance signal consistency. With an unbalanced resistance of under 2 %, loop resistance limited to 115 Ω/km, and dielectric strength between wires and shield rated at 1 000 V DC/700 V AC, the ZB9020 maintains uniform electrical performance under variable loads.
Beyond raw electrical metrics, the ZB9020 features 40 dB shielding attenuation to suppress electromagnetic interference, crucial for industrial automation near heavy machinery. The recorded signal running time of 5.3 ns/m supports high data rates, complementing its Cat.5–based electrical parameters. The cable is tested to withstand a test voltage of ≥ 2 000 V, underscoring its durability and safety. Compatible with standard Ethernet and EtherCAT networks, it meets industry expectations for reliable, low-loss data transfer. In industrial applications, using the ZB9020 translates to enhanced uptime, accurate synchronization across devices, and simplified system integration, yielding improved efficiency and productivity.
