Bus Cables
Profibus L2 ,7-wire
Application:
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
