Application

Engineered for durability, the SABIX® R flex series is built to excel in demanding railway applications. This continuous flex, low smoke halogen-free (LSHF) connection cable features black numbered conductors and improved fire performance, rated for 500 V and up to +90°C. Its SABIX® Ultra jacket provides exceptional resistance to harsh environments, ensuring long service life and reliable performance. Compliant with EN 45545-2, UN/ECE R118, CE, and RoHS, the R flex meets the highest international safety and performance standards. Halogen-free, UV-, oil- and chemical-resistant, it is well-suited for both interior and protected outdoor installations. Typical applications include door control systems, protective tube routing, and inter-wagon connections in rail cars and railway machinery. Designed for light to medium mechanical stress, the SABIX® R flex series delivers dependable connectivity and safe operation under continuous flex conditions.
