4 Mounting
Mount the sensor using a suitable mounting bracket (see the SICK range of accesso‐
ries).
Figure 16: Alignment of the sensor relative to the object direction
Note the sensor’s maximum permissible tightening torque of < 0.4 Nm.
Note the preferred direction of the object relative to the sensor, cf. see figure 16,
page 21.
5 Electrical installation
Operation in standard I/O mode:
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Male connector connection: Pin assignment
– Cable: Wire color
Only apply voltage/switch on the voltage supply once all electrical connections have
been established.
