8.2.2 Connection with M12 round plug connectors
In order to implement detachable connections, the cable connections for the field and
system bus and for sensors and actuators, as well as for the 24V supply voltage can be
designed with plug-in connectors.
Here, freely adjustable M12 flanged connectors with metric M16 x 1.5 threads should be
used for installation in the relevant housing ((SK TI4-
…(-BUS)).
This allows the use of angled or straight M12 round plug connectors for the cable
connection.
If required, Getriebebau Nord GmbH can equip the device to be delivered accordingly, or
can enclose the required plug with the delivery.
EMC compatible assembly is carried out in the same manner as for the assembly of the
cable glands (Section 8.2.1 "Fixed connection (cable gland)
").
8.2.3 Round plug connectors
Getriebebau Nord GmbH offers a selection of suitable plugs and couplings, which can be
installed in the connection units of the frequency inverters or the field bus module, or
enclosed with the delivery as required. The corresponding plugs, couplings and Y
connectors are also commercially available. However, a limited selection can be obtained from Getriebebau
NORD GmbH.
Coding
Round plug connectors are coded. Coding is by means of a pin or a groove on the contact base. The most
common codings are the so-called A and B coding. This serves to protect against incorrect coupling of the
various field bus systems.
