LSZH series PROFIBUS
Shielded Pairs
Balanced pair for Profibus system data bus. Use in closed environments with a high concentration of people (airports, hospitals, trains, cinemas, shopping centers, tunnels) and in control rooms with electronic equipment sensitive to the exposure of corrosive gases. Installed in conduits, trays, cable ladders, in direct open air or indoors, buried in a trench or in ducts.
