Interbus cable is designed for remote applications. Available for data transmission with 3 pairs only or as composite cable with 3 data pairs plus an additional 3 power cores.
Both the 3 pair and the composite 3 pair & 3 core options are available in standard or superfine (hi-flex) stranding. LSZH (low smoke zero halogen) and LSF (low smoke and fume) versions for increased fire safety are generally available on request.
Unlike traditional ring systems Interbus uses one cable to route data back and forth to all devices, each device or unit will amplify the signal before sending it on to the next station.
Note: low smoke zero halogen / halogen free (LSZH, LSOH, LSHF, OHLS) should not be confused with LSF (low smoke and fume), an in-depth explanation is shown on our LSZH Control Flex front page.
