J-Y(St)Y (2 x 2 to 12 x 2) x 0.6 mm ø
(Communication cables as per VDE 0815/DIN 57815)
For interference-free transmission of audio, data and pulse signals. Suitable for permanent installation on and under plaster, in dry and wet rooms and on buildings outdoors.
The aluminium foil embedded in plastics and the additional copper drain wire provide 100% shielding against external electrical interference. The large production quantities resulting from the many possible applications make these cables especially good value for money.
Conductors: plain copper wire, 0.6 mm Ø = 0.28 mm2 . Core insulation: PVC, coloured.
Twisted structure: 2 cores are twisted to a pair, 2 to 12 pairs are then twisted together (in layers) and wrapped with an overlapping layer of transparent foil 0.019 mm Ø
Shielding: When the copper drain wire is earthed, the aluminium foil embedded in plastics provides 100% protection from external electrical interference. Drain wire Ø 0.4 mm (up to 10 pairs), Ø 0.6 mm (12 pairs or more).
Outer jacket: largely oil and petrol resistant PVC, light grey as per RAL 7032. Jacket wall thickness: 1.0 mm
With 2-pair cables the first pair has a red a-core and a black b-core; the second pair has a white a-core and a yellow b-core. With cables having more than 2 pairs, the a-core is red for the first pair (counting pair) in each layer and is white for all other pairs. The b-core follows a repeating colour sequence of blue, yellow, green, brown and black.
