Application
Note
The connections to this sensor are sealed
with stopping plugs to protect against dirt and
moisture. If not all of the connections are
used in your application, then seal the remaining stopping plugs on the sensor permanently or check during initial installation and
when performing regular maintenance work
that the stopping plugs are secure and impermeable. If necessary, tighten the stopping
plugs to a torque of 2 Nm.
