The cables are intended for connecting L2-BUS components (standard 486) and transmission of analogue and digital signals. Paired construction ensures good symmetry with respect to earth, while the double screen protects against interferences from external electromagnetic fields, what guarantees very good transmission quality. Cables may be used in dry and damp rooms, outdoor and are suitable for fixed installations. Outer sheath is UV resistant. Cables classified according to EN 50575 (CPR).
