LiYCY  PVC-insulated control cable, with Cu screen cores with imprinted numbers, flexible, with inner sheath

Applications

These screened flexible control and interconnecting cables are used in instrumentation and control engineering where low current consumptions are required and transmission of the data must be continuous, e.g. in industrial electronics, computers, information and transmission systems, office machines and precision mechanics. These cables are suitable for voice communication in telecommunications systems, for pulse, signal and data transmission applications as well in public address and two-way intercom systems, i.e. for all applications where high-frequency interference can occur. Additionally these cables are ideal for applications in electronic equipment with subminiature plug connectors and plug-in systems where screened control cables are seeded in the smallest dimensions. These cables are also suitable for flexible and permanent installation in dry rooms.

Characteristic features

•  The design and construction optimizes the facility to provide more conductors with relatively smaller outer diameters.

•  Special PVC-insulated conductor and sheath compounds guarantee first-class mechanical properties and high flexibility of the cable

Durability

•  The PVC-insulated sheath is largely resistant to oils (depending on the type of oil), excluding VDE 0472 part 803.

•  Chemical resistance for PVC refer also to the Table of Technical Guidelines.
