Cable Structure
-
- Copper wire bare, stranded
-
- Wire structure:
- 0.5 mm²: 7 x 0.3 mm
-
- Conductor insulation: semirigid PVC
-
- Conductor identification: color coded, per bundle:
- Pair No. 1: conductor a = blue; conductor b = red
- Pair No. 2: conductor a = gray; conductor b = yellow
- Pair No. 3: conductor a = green; conductor b = brown
- Pair No. 4: conductor a = white; conductor b = black
-
- Conductors stranded in pairs with optimal lay lengths, 4 pairs stranded into bundles with optimal lay lengths, bundles stranded in layers with optimal lay lengths
-
- Bundle identification: synthetic helix with printed digits
-
- Drain wire, tinned copper, stranded (0.5 mm² = 7 x 0.3 mm)
-
- Shield: plastic-coated aluminum foil (St), approx. overlap 25%
-
- Outer jacket: PVC
-
- Jacket color: see datasheet
-
- Length marking: in meters
Properties
-
- pair stranding with short and varied lay lengths within a bundle, leads to good crosstalk attenuation values
Tests
-
- flame-retardant acc. to DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1-2
-
- certifications and approvals:
- EAC
Notes
-
- the conductor is metrically (mm²) constructed, AWG numbers are approximated, and are for reference only
-
- 2-pair cables: conductors stranded in a star quad
-
- with blue jacket for installation in intrinsically safe systems (ignition protection type -i-) in explosion-endangered areas according to DIN VDE 0165-1 / DIN EN 60079-14 / IEC 60079-14, Section 16.2.2
Application
-
- RD data transmission cables are used in measurement and control technology, as well as in control stations of industrial plants. The cables are used for the transmission of analogue and digital signals up to a frequency of approximately 10 kHz. They are suitable for fixed installations inside buildings.
