The low-frequency data cable UNITRONIC® Li2YCYv (TP) 2x2x0.5 from Lapp is a flexibly designed control cable for use in control, regulation, and measurement circuits. It is particularly suitable for applications requiring electromagnetic compatibility (EMC) and is universally used at machine interfaces where data and signal transmission in the low-frequency range is required. The cable is designed for occasional movement and can also be installed outdoors, provided the temperature range is observed. It features UV- and oil-resistant material, which extends its service life in demanding environments.

Applications

The cable is suitable for use in dry, damp, and wet environments. It is used in industrial plants, automation systems, and machine building applications where reliable signal transmission must be ensured despite electromagnetic interference. The wire identification follows the colour code DIN 47100, enabling clear identification of individual conductors and minimizing wiring errors.

Functions and Features in Detail

The cable features a copper braided shield with high coverage, providing excellent protection against electromagnetic interference. The twisted pair (TP) configuration with short lay lengths ensures good decoupling of the conductor circuits, improving transmission quality. The low-capacitance conductor insulation allows for long transmission distances without significant signal loss. The conductor colour coding according to DIN 47100 ensures unambiguous assignment of individual conductors.

Technology Explained Simply

The designation Li2YCYv (TP) describes the construction: Li2 refers to the conductors (two pairs), YCYv stands for PVC insulation and shielding, and (TP) indicates the twisted pair configuration. The copper braid shielding protects signals from external electromagnetic influences. The twisted pair reduces inductance and capacitive coupling between conductors, enhancing signal integrity. The PVC insulation is flexible and resistant to UV radiation and oil.

Compatibility and Accessories

The cable is designed for use in control and regulation systems and can be connected to standard connectors and sockets designed for the conductor colour code DIN 47100. It is suitable for outdoor and underground installation, provided environmental conditions such as temperature and humidity are considered.

Installation and Mounting

The cable is flexible and easy to install. During installation, proper securing and avoidance of sharp bends must be ensured to maintain mechanical integrity. The shielding should be connected at both ends to ensure EMC protection. Outdoor installation requires observing the permissible temperature range.

Operational Advantages

The cable offers high reliability in signal transmission, even in electromagnetically disturbed environments. The UV- and oil-resistant PVC insulation increases service life, especially in industrial applications. The unambiguous conductor identification according to DIN 47100 reduces errors during installation and maintenance. The twisted pair configuration and shielding ensure good decoupling of conductor circuits and minimize interference.
