Profibus L2 ,7-wire


This system cable is used to interconnect L2-BUS components. This cable is an economical solution for the cell

and field area. For the information exchange between different automation systems as well as for

communication with the connected decentralized field units, serial field bus systems are used. With this cord

design, the type mentioned here is suitable for laying in regular mobile applications and is equipped with a

special PVC jacket
