Product Description
This KNX bus cable is specially developed for building automation and smart home systems. With a double-core twisted pair structure and shielding layer, it provides excellent protection against signal loss and interference, ensuring accurate data transmission even over long distances.
The conductor size of 2×2×0.8 mm² allows stable performance in both residential and commercial installations. The robust outer sheath, made from weather- and UV-resistant material, makes the cable suitable for indoor and controlled outdoor environments.
Typical applications include KNX protocol-based control of lighting, shading, HVAC, and security systems. Whether for new installations or retrofit projects, this bus cable offers a reliable backbone for intelligent network communication.
