(5).2 Mounting the sensor mounting ring
The spindle should be so designed that it will construct the clearance fit between the outer diameter of the sensor
mounting ring and the fitting part of the spindle as shown in the diagram below (The error in the fitting size may cause
the increase of the detection error). As shown in the figure below, push the sensor mounting ring from CN1 sensor
side, so that it will contact with the fitting part closely. Check that the gap of between the detection ring and the sensor
element is 0.08mm or more by using feeler gauge.

NOTE
・It is recommended to locate the sensor mounting ring mechanically as indicated above. It is not advisable to adjust it by
measuring the eccentricity of the outer diameter of the sensor mounting ring.
