The low-frequency data cable UNITRONIC® LiYCY (TP) 12x2x0.25 from Lapp is a shielded, flexible control cable for signal and data transmission in the low-frequency range. It is suitable for fixed installation in dry and damp rooms as well as for light mechanical stress. The cable is used in applications such as computer systems, electronic control and regulation devices, office machines, and weighing scales. Due to its compact design and twisted pair (TP) configuration with short pitch lengths, it is universally applicable at machine interfaces and ensures good decoupling of conductor circuits.

Applications

The cable is designed for use in industrial and office installations where reliable data and signal transmission is required. It is suitable for applications where electromagnetic interference must be avoided, such as in automation technology, measuring instruments, or in connecting control devices. The PVC outer sheath is conditionally oil-resistant, allowing use in environments with minor oil contact. The cable is intended for use in dry and damp rooms, but not for permanent outdoor use or high mechanical stress.

Functions and Features in Detail

The UNITRONIC® LiYCY (TP) 12x2x0.25 features 12 pairs, each consisting of two conductors with a cross-section of 0.25 mm². The pairs are twisted as twisted pairs (TP), enabling effective decoupling of signal circuits and reducing interference from electromagnetic interference. The wire colour coding follows DIN 47100, ensuring unambiguous identification and assignment of conductors during wiring. The cable is equipped with a copper braided shield with high coverage, providing high electromagnetic interference protection.

Technology Explained Simply

The twisted pair (TP) technology means that individual conductor pairs are arranged in a spiral configuration. This construction minimizes induction of interference voltages from external electromagnetic fields, as the interference in both conductors of a pair is approximately equal and cancels out. The copper braided shield surrounds the entire cable and protects the internal conductors from external electromagnetic interference. The PVC insulation and outer sheath ensure mechanical stability and chemical resistance against minor oil contact.

Compatibility and Accessories

The cable is designed for use in systems requiring fixed installation and high signal quality for low-frequency applications. It is compatible with standard connectors and sockets designed for control cables with a 0.25 mm² cross-section. The use of appropriate cable lugs, connectors, or connection parts is required to ensure a secure and durable connection. The exact selection of accessories depends on the specific application and connection points.

Installation and Mounting

The cable is intended for fixed installation and should be installed according to regulations for electrical installations. Mounting does not require special tools, but careful securing and routing of the cable is necessary to avoid mechanical stress. The use of cable loops or cable ties is recommended to ensure proper routing. The cable must not be excessively bent or kinked to maintain the integrity of the conductors and the shielding braid.

Operational Advantages

The UNITRONIC® LiYCY (TP) 12x2x0.25 offers high electromagnetic interference protection through the copper braided shield and twisted pair structure. Its compact design enables a small outer diameter, which is advantageous for routing in confined spaces or cable ducts. The classification of fire behaviour according to EU Directive 305/2011 (BauPVO/CPR) ensures that the cable meets current safety requirements. The cable is insensitive to electromagnetic interference, ensuring reliable signal transmission even in sensitive environments.
