Profibus DP single pair 24-22awg violet cable

Profibus DP single pair cables are available with solid or stranded conductors and are designed for process and field communication in cell networks. They can be supplied with steel wire armour (SWA) for protection against mechanical damage. 

Sheath options: PUR sheathing is tougher than standard PVC, PE Duct is suitable for use in ducts, FEP is suitable for high temperature applications, SWA is suitable for direct burial and LSZH provides increased safety in the case of fire.

The Profibus (process field bus) protocol has been widely adopted for production and process automation applications providing transmission rates up to 12Mbits/sec.

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.
