3ZG2 - Smart Profile Sensor
Specifications
Sensor Heads
Note: 1 .Obtained by setting an OMRON standard measurement object at the
measurement center distance and determining the average height of
the beam line. The conditions are given in the table below. However,
satisfactory resolution cannot e attained in strong electromagnetic
fields. The minimum resolution of the ZG2-WDS8T/WDS3VT is
0.25 µm, even when the average number of operations is increased.
Resolution does not go any lower.
2 .The tolerance for and ideal straight line obtained by determining the
average height of and OMRON standard measurement object for the
beam line. The CCD high-resolution mode is used. Linearity varies de-
pending on the measurement object.
3. A value attained by using an aluminum jig to secure the distance be-
tween the Sensor Head and the measurement object. The CCD stan-
dard mode is used.
4 . Defined as 1/e2(13.5%) of the center light intensity. This may be influ-
enced when light leakage also exists outside the defined area and the
reflectivity of the light around the measurement object is higher than
that of measurement object.
