BUS LD is a screened, twisted paired cable for bus systems with a data transmission rate up to 10
MBit/s. The twisting of the conductors into pairs ensures maximum interference suppression of the individual
signals. The copper screening protects against external electromagnetic influences.
Cables of this composition are intended for limited flexible use and for permanent installation in dry and damp
interiors.
Applicable connectors: D-Sub-Connector, 9-pins; Round-Connector, 9-pins (system of protection IP 65)
