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