7 facts about PAAR-TRONIC-Li-2YCY data cable

The PAAR-TRONIC-Li-2YCY cable features core identification according to DIN 47100, with each core assigned a specific color code, making connection and inspection quick and precise. With PE insulation, the cores are stranded into pairs with optimal lay lengths, and these pairs are then stranded into layers, forming a robust cable structure. This design ensures stable signal transmission, reduces interference, and minimizes crosstalk between pairs.

The cable is designed with multiple protective layers: foil wrapping, a tinned copper drain wire, and a braided screen of tinned copper wires with approx. 85% coverage. Thanks to this structure, PAAR-TRONIC-Li-2YCY provides excellent electromagnetic compatibility (EMC), ensuring signal integrity even in industrial environments with heavy electronic equipment and interference sources.

A practical advantage of this cable is its grey PVC sheath with meter marking in the metric system. This makes measuring, cutting, and installation quicker, more accurate, and less wasteful. Moreover, with its PVC sheath, the cable has a minimum bending radius of 7.5 times the outer diameter for fixed installation and 12 times for flexible use.

Within the PAAR-TRONIC-Li-2YCY cable series, the version with the highest number of cores includes 20, which means 10 stranded pairs. In addition, the cable is available in versions with 2, 3, 4, and 8 stranded pairs, with cross-sections of 0.22 mm², 0.34 mm², and 0.5 mm², offering flexible options depending on system requirements. With just one cable, multiple signal channels can be transmitted simultaneously – highly convenient for automation or industrial communication projects.

The conductor resistance at 20°C for PAAR-TRONIC-Li-2YCY differs depending on the cross-sectional area:

• 0.22 mm²: max. 93.0 Ω/km
• 0.34 mm²: max. 57.5 Ω/km
• 0.5 mm²: max. 39.3 Ω/km

These figures show that the larger the cross-section, the lower the resistance, resulting in more efficient and stable signal transmission over longer distances. Engineers can choose the right cross-section according to project requirements to achieve optimal performance.

Although PAAR-TRONIC-Li-2YCY supports high transmission rates, especially for RS 422 and RS 485 interfaces, it is designed for fixed installations in dry, damp and wet rooms. Outdoor use is not recommended, as weather conditions and UV radiation may reduce its lifespan and compromise signal quality.

PAAR-TRONIC-Li-2YCY has a peak operating voltage of 250 V and is suitable only for transmitting data and control signals. It is not designed for high power current installation purposes. For this reason, PAAR-TRONIC-Li-2YCY is classified as a dedicated data cable, focusing on reliable signal transmission and interference resistance rather than power delivery.

If you are looking for a data cable with optimized stranded pairs, outstanding interference protection, and stable transmission speed for industrial systems, PAAR-TRONIC-Li-2YCY is the reliable choice. Contact HELUKABEL today for detailed consultation and quick ordering!
