UNITRONIC SPEAKER LIYY

UNITRONIC SPEAKER LIYY cables are flexible, low-frequency signal cables designed for audio and voice transmission in industrial environments. These cables feature a stranded tinned copper conductor, PVC insulation, and a PVC outer sheath, offering good flexibility and resistance to mechanical stress. The LIYY designation indicates a shielded version with a tinned copper braid, providing protection against electromagnetic interference (EMI). Typical conductor cross-sections range from 0.14 mm² to 1.0 mm², with operating voltages up to 250 V and temperature ranges from -30°C to +70°C. They are available in multiple pair configurations, such as 2x0.14 mm², 4x0.25 mm², or 6x0.5 mm², making them suitable for distributed audio systems in automation.

These cables are primarily used in industrial communication systems, including public address systems, intercoms, and background music installations in factories, warehouses, and commercial buildings. They are also deployed in control cabinets for signal transmission between audio amplifiers and speakers, as well as in building automation for voice alarm systems (VA) and emergency evacuation systems. Their shielded design ensures reliable signal integrity in electrically noisy environments, such as near variable frequency drives (VFDs) or motor control centers.

Key subcategories include standard LIYY cables with PVC sheath, halogen-free versions for fire safety, and custom lengths with pre-terminated connectors. Common article codes follow the pattern "UNITRONIC SPEAKER LIYY 2x0.14" or "UNITRONIC SPEAKER LIYY 4x0.25", where the first number indicates the number of pairs and the second the conductor cross-section in mm². For example, article code LA51-2-0.14 corresponds to a 2-pair cable with 0.14 mm² conductors. Other variants include shielded versions with additional foil screening for higher EMI protection.
