- Pair no. 4: a-core = white; b-core = black
- Cores 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
- Foil wrapping
- Drain wire, tinned copper, stranded (0.5 mm² = 7 x 0.3 mm)
- Screen: plastic-coated aluminium foil (St), approx. overlap 25%
- Outer sheath: halogen-free polymer
- Sheath colour: grey (RAL 7032)

- halogen-free
- pair stranding with short and varied lay lengths within a bundle, leads to good crosstalk attenuation values

- corrosiveness of combustion gases acc. to DIN VDE 0482-754-2 / DIN EN 60754-2 / IEC 60754-2
- bundle fire test acc. to DIN VDE 0482-332-3-24 / DIN EN 60332-3-24 / IEC 60332-3-24
- smoke density acc. to DIN VDE 0482-1034-1+2 / DIN EN 61034-1+2 / IEC 61034-1+2
- certifications and approvals:
- EAC

- the conductor is metrically (mm²) constructed, AWG numbers are approximated, and are for reference only
- 2-pair cables: cores stranded to a star quad

- Halogen-free data transmission cables are used in measurement and control technology for the transmission of digital and analogue signals up to a frequency of 10 kHz. These cables are used inside buildings and outdoors, however, not without UV protection.
