Benefits

  • In order to reduce costs, the multi-wire copper braided conductor has been provided for Maxi TERMI-POINT® connecting technology. This (semi-automatic) wiring method considerably reduces the time and the costs required for installation.
  • Decoupling of circuits by means of
    twisted-pair (TP) design (crosstalk effects)

Application range

  • RD-Y(ST)Y is used as a data transmission cable for applications such as monitoring systems and control units
  • Measurement, control and regulation technology and also in control rooms of power plants and industrial facilities
  • Suitable for transmission of analogue and digital signals up to a frequency of about 10 kHz
  • Designed for fixed installations in enclosed rooms.
