Application
Engineered for durability, the CATLine CAT 7A R flex series is built to excel in demanding railway and industrial environments. These continuous flex, low smoke halogen-free (LSHF) SABIX® CAT 7A Ethernet cables feature colored star quad stranded conductors or twisted pairs, designed in compliance with EN 45545-2 railway standards. Rated for 90 V and up to 90°C, they are built with a special SABIX® jacket that ensures durability and long-term resistance in harsh conditions. Certified to EN 45545-2, UN/ECE R118, CE, and RoHS, the CATLine 7A R flex series meets strict international safety and performance requirements. Fully compliant with fire protection requirements R15 (EL1A) and R16 (EL1B) for Hazard Levels 1–3, it is specifically engineered for CAT 7A control systems in trains and railway infrastructure. With excellent oil and fuel resistance, this continuous flex cable ensures safe, reliable, and high-speed data transmission in critical applications.
