(2) Coupling device
installation precaution
1.
2. If the selected coupling device is larger than necessary (When
used in high vibration/shock environments), the load which is
applied to the shaft by the vibrations/shocks will be increased
by the weight of the coupling device.
3. Be sure to select a coupling device with an adequate
transmission torque surplus relative to the sensor shaft's
torque.
Explanation

Precaution
The selection of a larger
coupling than necessary
will increase the shaft
load which is caused by
the mounting error
amount.
Excessive force applied
to the shaft can deform
the coupling and reduce
durability.
