Use of cable

as fieldbus cables for SafetyBUS systems for high flexible applications (e.g. power chains, gantry robots, pick&place units, conveyors, machine tools, automated production systems, etc.), in the field of factory automation.

SafetyBUS is a safe, open fieldbus system, which is optimized for the transmission of data relating to machine safety: timing and content consistency of the data have the highest priority here.

Special features

  • low adhesion
  • largely resistant to grease, coolant fluids and lubricants
  • oil-resistant: acc. to DIN EN 60811-2-1
  • EMC compliant shielding
  • max. cable lengths for a bus segment at stated transmission rate: 
              50 kbit/s-max.1,0km | 125 kbit/s-max.500m | 250 kbit/s-max.250 m | 
               0,5Mbit/s-max.100m
