  • Fast information exchange through future-proof Single-Pair-Ethernet technology.
  • For transmission of analogue and digital signals in the frequency range up to 600 MHz and up to 40 m distance.
  • A single-pair cable design saves weight and space. Small bending radii and outer diameters are essential for the connection to the field level.
  • Power-over-Data-Line-capable cable according to IEEE 802.3bu for simultaneous power and data supply of SPE terminals with low energy requirements (up to 50 W).
  • Ideal protection against electromagnetic interference due to double shielding of aluminum-clad foil and copper braided shield with high coverage (SF/UTP).

Application range

  • For structured cabling according to DIN EN 50173 and ISO/IEC 11801.
  • For Single-Pair-Ethernet applications 100Base-T1 according to IEEE 802.3bw and 1000Base-T1 according to IEEE 802.3bp.
  • Can be used in dry or damp rooms
  • Suitable for medium mechanical stress.
  • Flexible use
