Shielded Fieldbus Cables are specialized high-frequency signal transmission cables designed to route real-time industrial communication protocols—such as PROFINET, EtherCAT, PROFIBUS, and CANopen—across factory floors without signal degradation or electromagnetic interference (EMI). Featuring tightly controlled impedance characteristics and comprehensive dual-layer shielding, these cables safeguard high-speed data packets from high-voltage motor drives and welding equipment. Key hardware features typically include twisted pair conductors, combination aluminum foil and tinned copper braid shielding, characteristic impedance matching (e.g., 100-ohm or 120-ohm), and rugged PUR, PVC, or halogen-free outer jackets.
