Unitronic LiYY

From Lapp, Unitronic series LiYY data cables have been developed from tried and tested VDE 0812 cables. LiYY designated cables are designed for multi-functional use, and are commonly used in signal and data transmission applications.

The multi-core cable is comprised of fine-wire bare copper strands, with a PVC core insulation and sheath.

This Unitronic low-frequency data cable has a small outer diameter for space-saving installations, and is also flame retardant. It can be used in dry or damp indoor environments, and is suitable for occasional flexing.

Features and Benefits

• Space-saving installation
• DIN colour code
• Transparent outer sheath made from special PVC-based mixture
• Flame-retardant in accordance with VDE 0472, part 804, test type B (IEC 332.1)
• Operating temperature with occasional flexing: -5°C to +70°C
• Operating temperature in fixed installation: -40°C to +80°C

Applications

The Lapp Unitronic LiYY cable is suitable for many control and signal applications, and is commonly found in industrial computers. It can also be used in;

• Process and control equipment
• Office machines
• Measuring equipment

Accessories

Unitronic LiYY cable should be use din conjunction with accessories that match its capabilities, such as Lapp cable glands, such as the easy-to-install Skintop range.

• 361-9994 is an M12 IP68 Skintop ST-M Cable Gland
• 365-8422 is an M16 IP68 Skintop ST-M Cable Gland
• 365-8438 is an M20 IP68 Skintop ST-M Cable Gland
• 365-8444 is an M25 IP68 Skintop ST-M Cable Gland
• 362-0001 is an M32 IP68 Skintop ST-M Cable Gland

Features and Benefits

• Multi-strand bare copper core
• PVC conductor insulation and external sheath

Standards

DIN 47100, IEC 60332-1

LAPP Control Cable, Multi-Strand Type, 12A Current Rating - UNITRONIC LiYY Series - 0028620-25

Move power and signals around your machinery using this 20-core control cable from LAPP. It has a minimum bend radius that's four times its 12.4mm diameter in fixed installations and ten times its diameter in occasionally flexing applications. This means it's flexible enough to shape to awkward setups without compromising signal delivery. The tough PVC outer jacket of this cord gives insulation protection to help prevent shocking incidents.

Features & Benefits

• Highly conductive copper conductors with a 0.75mm² cross-sectional area for reliable transmissions
• 12A current rating makes it safe to use in medium-duty systems
• Oil-resistant to accommodate direct integration into machinery

Applications

• Robotics systems
• Aerospace engineering
• Server rooms
• Packaging facilities

Is this control cable flame-retardant?

Yes, it is, thanks to its durable grey PVC sheath that has self-extinguishing properties.

How long is this cable?

It's 25m long, so you have plenty of reach for one or sufficient stock for multiple applications.
