Important Notes Note that screened multi-core twisted-pair control cable is required as BUS line , e.g. UNITRONIC® BUS CAN
2 x 2 x ... mm2 or RE-2YCYV-fl 2 x 2 x ... mm2 or the control cable assembly available as add-on equipment.
Connector
The cable length dictates the baud rate (data transfer rate) between the bus nodes, and the total power consumption of
the sensor dictates the conductor size.
