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.
Attention
Damaged cable installations may result in additional electrical
connections. This can disturb the measured values.
5.1.1 Mounting instruction for M12 connectors with key way
These connectors have a positioning nose 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.
A Positioning slot at female connector
B Positioning nose at male connector
C Threaded arresting ring
D Connector assembly ring.
Never turn this ring when arresting the plug
with the arresting ring C.
Fig. 12: Positioning facility and arresting ring
When the connection is established correctly as described, plug and socket can be arrested with
the arresting ring.
Attention
Turn only the threaded arresting ring C !
If the whole plug becomes turned, the locking facility and the contact
pins will break and the connector will become useless.
Attention
Under any circumstances it is not allowed to use any part of a
plug connection as a holder for the installation of the
counterpart.
