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 analog and digital signals up to a frequency of about 10 kHz
- Designed for fixed installations in enclosed rooms.
Benefits
- In order to reduce costs, the multi-wire stranded copper cable has been provided for Maxi TERMI-POINT® connecting technology.
This wiring method (semi-automatic) considerably reduces the time and the costs required for installation. - Decoupling of circuits by means of
twisted-pair (TP) design (crosstalk effects)
