The screw connection between sensor and surface is relatively simple. A blind hole for the
mounting bolt has to be drilled on a suitable point on the machine surface. Normally this is a
metric thread M6 with 1 mm slope. The blind hole has to be absolutely perpendicular to the
surface to avoid tensions of the sensor chassis during tightening the screw. After deburring
and cleaning the surface the sensor is tightened at the mounting bolt with screw lock by hand.
For the screw lock it is recommended to use Loctite 243. If a torque wrench is available, the
sensor can be tightened with 3 to 6 Nm. Screw lock is not needed in this case.
Note:
The maximum torque of 6 Nm must not be exceeded. A Torque above this level can
result in a destroyed thread or a failure of the sensor.

If a screw connection between sensor and surface is not possible, a mounting base with an
integrated thread hole can be glued on the machine surface. The sensor itself is then screwed
on the mounting base. An absolute requirement for gluing a mounting base is a clean, color
free and grease free surface. Commercial two component epoxy resin glue is suitable for the
permanent installation of a mounting base. It is recommended to use an epoxy resin glue with
metal. These glues are applicable up to 120 °C. The gluing process depends on the glue and
has to be done according to the manual.
