4.2 GND connections
Minimize noise by connecting the shield to ground.
Make sure that ground is not affected by noise.
5 - Output signals
A positive increment of the signal values is carried
out by rotating the magnetic ring clockwise when
the sensor is mounted as shown in Figure 1.
The number of pulses is proportional to the
mechanical travel as the frequency is proportional
to the rotation speed of the magnetic ring.
The order code indicates the interpolation factor, if
you want to know the number of edges per
revolution (intended after multiplying by 4),
multiply the interpolation factor by the number of
magnetic poles in the magnetic ring.
Example
SGSM-Y-2-64-… interpolation factor = 64
MRI/72-64-3-...
64 magnetic poles
Number of edges per revolution = 64 x 64 = 4096
