BZi sensor installation
As shown below, install ring A and ring B.
- Press the rings through the
sleeve, then press the sleeve
into the shaft. Ensure that
the A/B phase ring and the Z
phase ring are joined closely
with each other.
- Ensure that a displacement
between the middle point
(9.3 mm) of the thickness of
the A/B phase ring plus the
Z phase ring and the center
of the sensor lies within ±0.5
mm.
- Ensure that the swing of the
sleeve relative to the center
of the shaft lies within 0.005
mm.
- Ensure that the swing of the mounting ring relative to the center
of the shaft lies within 0.02 mm.

NOTE
1 Select a tightening allowance from the table above according to the maximum speed
and type of a ring used. A failure to satisfy a tightening allowance indicated above
can cause idle running or damage.
2 Each ring cannot be used at a speed higher than the indicated speeds. For the
maximum allowable speed of each ring, see "Sensor ring" described earlier.
