Benefits

Highly flexible cable design means excellent product performance.
Durable cable chain use with medium travel distances or increased acceleration (LAPP performance class “Core Line”).
Shorter core stranding allows very small bending radii.
Low-capacitance core insulation for long transmission paths.
Ideal protection against electromagnetic interference thanks to copper screening braiding with a high degree of coverage.
DESINA-compliant PVC outer sheath with increased resistance to mineral oil-based lubricants.

Applications

For connecting frequency converters and servo motors.
Cable design allows highly flexible, continuously flexing use in moving machine parts and in the cable chain.
Especially for environments where electromagnetic compatibility (EMC) is required.
Can be used in dry, damp or wet environments.
Suitable for medium mechanical stress.
The PVC outer sheath is resistant to acids and alkalis.
