2.2.3 Hybrid connectors (part one)

Hybrid connectors simplify installation of PROFIBUS stations by wiring the voltage supply and the PROFIBUS cable in a single connector. Preassembled cables, which are available in different lengths from the cable manufacturers, provide a particularly simple solution. When it is necessary to assemble hybrid connectors on site, the manufacturer’s instructions must be followed.

The contacts of the hybrid plug are generally crimped. Only suitable crimping tools should be used; these are generally available from the connector manufacturer. Only correctly crimped connections ensure a permanent, high-quality connection.
