2.2 Assembling connectors

Several types of connector are available to connect PROFIBUS copper cables to PROFIBUS stations. The 9-pin Sub-D connector is used for the area inside control cabinets. Outside control cabinets, the M-12 or the hybrid connector can be used. The PROFIBUS station determines the type of connector that is used .

Different connectors require different wiring techniques; therefore it is not possible to provide general instructions for assembling plug connections. The types of connectors most frequently used are: The 9-pin Sub-D connector and the 5-pin M-12 connector (3 contacts assigned) for PROFIBUS-RS 485 and the 4-pin M-12 connector for PROFIBUS-MBP (PA) (PROFIBUS-PA). The hybrid connector is also available for PROFIBUS-DP.

You should also always observe the instructions of the connector manufacturer in addition to the following assembly examples.
    

The type of connector is determined by the PROFIBUS station socket type. The PROFIBUS devices should be selected with this in-mind. Ensure that device connectors meet your requirements for the environment in which they are used.
