Seal the connection with the protective cap supplied
(type ISK−M8).
Use e.g. the following proximity switches from Festo:
electric proximity switch SME−10F−... /SMT−10F−...
(can be installed in sensor grooves of the drive profile).
If necessary, use an extension cable type KM8−M8−....
Connecting the reference switch:
·
Use the correct switch type normally−open" for the
reference switch in the PNP variant.
·
For connecting the reference switch use a cable with
rotating thread sleeve on the end of the cable, e.g. type
SME−10F.../SMT−10F... or extension cable type KM8−M8−....
·
When selecting the sensor, note that the accuracy of the
switchover point of the sensor can affect the accuracy of
the reference point.

During installation, observe the position of the sensor
relative to the index pulse; shift the sensor if necessary
(see warning INDEX PULSE WARNING", section 6.3).
