Attaching the sensor mounting ring
Provide an inlow on the machine side and then attach the sensor
mounting ring by engaging the outer surface of the sensor mounting
ring in the inner surface of the inlow. (The sizes related to the inlow
parts on the machine side must meet the conditions shown below so
that the detection accuracy is not degraded.) When securing it by
screws, push the mounting ring from the CN1 sensor side against the
inlow and then secure it as shown in the following figure. After
securing it, use a feeler gage or other tool to verify that the gap
between the sensor ring and the sensor is greater than 0.08 mm.

NOTE
- Provide an inlow, if possible, on the machine side and engage the sensor mounting ring to the inlow. Do not tap the
outer surface of the sensor mounting ring for centering.
