General instructions

The sensor cables should be kept as short as possible in order to minimize the influence of
electromagnetic noise. Cable shields must be connected according to the connection diagrams
only and should not have any additional connections.
5.1.1 Mounting instruction for M12 connectors with arresting ring
These connectors have a positioning key at the plug and a positioning slot at the receptacle. These
items are designed to prevent incorrect connecting positions.
For this reason if plug and receptacle are connected together then these positioning features
should fit to each other.
Only then it is possible to connect plug and receptacle without force and with proper pin
configuration.
Fig. 22: Positioning facility and arresting ring
When the connection is established correctly as described, plug and socket can be arrested with
the arresting ring.
