Assembling the sensor head

The sensor head housing has bore holes with M4 threads.
Using screws, the sensor head can be connected two
different ways to the machine part: using either the M4
thread in the sensor head or the M3 thread in the machine
part.
Mounting via the thread in the machine part
► Guide the screws through the housing and screw into
the machine part (see Fig. 4-3 and Tab. 4-1).
