Product Description:

The X20CA0E61.00150 is a prefabricated Ethernet cable produced by B&R Automation for the X20 Fieldbus Input Output Modules series. It serves as the physical layer link between a controller and distributed I/O stations in industrial automation, supporting deterministic data exchange along the system backplane. By delivering a ready-to-install assembly, the manufacturer eliminates on-site termination work and reduces wiring errors in cabinet or machine environments. Its construction supports harsh conditions common to factory equipment and preserves the electrical characteristics needed for high-speed fieldbus communication.

The cable has an IP65 protection rating, so the jacket resists dust ingress and low-pressure water jets when the assembly is installed outside control enclosures. Each core uses a 4x2x26 AWG conductor arrangement, and the eight data lines use tinned copper stranded 26/7 AWG conductors for flexibility and adequate cross-section. Termination is provided through an RJ45 to RJ45 connector pair that mates directly with the Ethernet sockets on X20 modules. The link conforms to Category 5e / Class D performance and carries signals up to 100 MHz, supporting Fast Ethernet bandwidth. A PVC outer jacket adds oil resistance, and the balanced pair insulation made of polyethylene helps keep impedance stable over temperature.

Electrical limits include a maximum loop resistance of 145 Ω/km at 20 °C, which helps keep voltage drop manageable on extended runs. The assembly is rated for continuous operation at 125 V and withstands a dielectric test of 1000 V applied between pairs. Insulation resistance reaches 5 GΩ/km at 20 °C, which helps prevent leakage currents in humid areas. An overall foil braid with 85% shield coverage reduces electromagnetic emission and helps protect the cable from external interference. The wire geometry uses four twisted pairs in a common bundle, and the strand lay supports repeated flexing during drag-chain motion.
