Product Description:

The X20CA0E61.00800 cable is produced by B&R Automation for the X20 Fieldbus Input Output Modules series. It serves as an Ethernet media link that carries power-limited signaling and real-time fieldbus traffic between remote I/O bases and the main controller in modular machine layouts. Its role is to provide a stable physical connection for distributed automation nodes that must exchange control data continuously during operation.

The round profile maintains a diameter of 6.7 mm ± 0.2 mm, so routing trays and glands can be sized precisely. Inside, four differential pairs follow a 4 × 2 × 0.16 mm² cross section and use tinned copper strands that keep loop resistance below 145 Ω/km at 20 °C. The geometry supports a line rate of 10/100/1000 Mbit/s, allowing the same cable to serve legacy controllers and gigabit network upgrades. Continuous working potential is rated at 125 V, permitting power-limited auxiliary circuits without extra isolation. Surrounding the cores, an aluminum-PET shield provides a screening density of 85%, which helps limit crosstalk and supports reliable operation on electrically noisy plant floors. A PVC outer jacket and polyethylene inner insulation complete the cable while maintaining flexibility for machine routing.

Additional reliability parameters complement the electrical profile. Core insulation maintains at least 5 GΩ/km at 20 °C, reducing leakage that could affect signal quality over long runs. The cable withstands a dielectric test of 1000 V to verify insulation integrity, and the molded over-jacket provides IP65 protection against dust and low-pressure water jets when mated with the designated M12 connectors. The pair twist and impedance window follow ANSI/TIA limits for Category 5e / Class D channels, so standard Cat 5e hardware can be used for compliant return-loss and near-end crosstalk performance across the full 100 m segment length.
