  0,5 mm² = 7×0,3 mm
• Core insualtion of PVC (Semi-Rigid-PVC)
• Core identification coloured
  pair-no.1: a-core = BU; b-core = RD
  pair-no.2: a-core = GY; b-core = YE
  pair-no.3: a-core = GN; b-core = BN
  pair-no.4: a-core = WH; b-core = BK
• Cores stranded in pairs
  (approx. 20 pitch/m ≙ 50 mm)
• 4 pairs stranded to a unit
  (unit labelled with numbers
  printed plastic helix)
• Units stranded in concentric layers
• Electrostatic screen of plastic coated
  aluminium foil and drain-wire tinned,
  0,5 mm² = 7×0,3 mm
• Outer sheath of PVC
• Sheath colour grey (RAL 7032)
  or blue (RAL 5015)
• with meter marking

Properties

• Twisted pairs with short different
  lay lengths within a bundle results
  to good crosstalk attentuation values
• The static screen protects the
  transmission circuits against outer
  electrical interferences
• The materials used in manufacture are
  cadmium-free and contain no silicone
  and free from substances harmful to
  the wetting properties of lacquers

Tests

• PVC self-extinguishing and flame retardant
  acc. to DIN VDE 0482-332-1-2,
  DIN EN 60332-1-2, IEC 60332-1 (equivalent
  DIN VDE 0472 part 804 test method B)

Note

• Cop.weight including drain-wire.
• Also available halogen-free type
  RD-H(St)H on request.
• Maxi-Termi-Point^® = registered trade
  mark AMP.
• AWG sizes are approximate equivalent
  values. The actual cross-section is in mm².

Application

The data transmission cables RD-Y(St)Y are used in measurement and control technology such as in control rooms of industrial plants and power stations. The cables serves for transmission of analog and digital signals up to frequencies of approx. 10 kHz. These cables offer considerable advantages by using the quick and economical connecting possibilities in Maxi-Termi-Point^® technique. This solderless connecting technique is defined by a compression termination that employs a spring-clip for the connection of the cable to a square rigid post without pre-stripping. For this technique it is necessary to have an exact 7-core stranded conductor and a Semi-Rigid-PVC. Suitable for fixed installation only inside of buildings. With blue outer sheath suitable for intrinsic safe systems.
CE = The product is conformed with the EC Low-Voltage Directive 2006/95/EC.
