Cable structure

Bare copper conductor, multi-wire
Conductor construction:
0,5 mm² = 7x0,3 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 = 7x0,3 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.
