PE/PVC data transmission cable, shielded PAAR-TRONIC-Li-2YCY 8x2x0.34 mm² grey, color-coded wires according to DIN 47100 21120

Shielded control cable – reliable data transmission in harsh conditions

This flexible control cable, catalog number 21120, is the ideal solution for transmitting signals in environments exposed to electromagnetic interference. The construction with twisted pairs and double shielding (foil and braid) ensures high-quality transmission over long distances. The cable is particularly recommended for RS 422 and RS 485 interfaces, where signal stability is crucial.

This cable performs well in both stationary and mobile installations, offering flexibility and reliability. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The gray outer PVC coating protects against mechanical damage and weathering (indoors).

Construction and properties ensuring optimal performance

The cable design is designed for maximum data transmission efficiency. Copper strands, twisted in pairs, minimize the impact of electromagnetic interference. In addition, the double shield – aluminum foil and copper braid – effectively suppresses noise and interference. The strand insulation made of special polyethylene (PE) provides high resistance to damage and long-lasting insulation.

• Strands: Multi-strand (class 2), made of unannealed copper, twisted in pairs to reduce interference.
• Shielding: Two-layer – aluminum foil and copper braid for maximum protection against interference.
• Insulation: Special polyethylene (PE) ensuring high-quality insulation and durability.
• Outer jacket: Polyvinyl chloride (PVC) resistant to mechanical damage and weathering (indoors).
• Strand cross-section: 0.34 mm², which provides adequate conductivity for control signals.
• Operating temperature: Flexible from -5°C to +70°C and stationary from -30°C to +80°C – a wide temperature range guarantees reliability in various conditions.

The cable complies with the Low Voltage Directive 2014/35/EU (CE marking) and has certificates confirming its safety and quality. The outer jacket is self-extinguishing and flame-retardant, increasing the safety of the installation.

Applications and installation

This cable is used in a wide range of electrical installations and industrial automation:

• Control systems: Transmission of control signals in machines and devices.
• Building automation: Connections of sensors, controllers and other devices in intelligent building systems.
• Industrial communication networks: Data transmission in RS-422 and RS-485 networks.
• Monitoring installations: Transmission of signals from cameras and other video surveillance devices.

The minimum bending radius of the cable is 12 x cable diameter during flexible operation and 7.5 x cable diameter for fixed installation, which facilitates assembly even in tight spaces. For optimal electromagnetic compatibility (EMC), it is recommended to make contact of the copper braid with the cable glands on both sides.
