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 be attained in strong electromagnetic fields.
| Mode | CCD Mode | Average No. of Operations | Measurement object | |
| Regular reflective | Diffuse reflective | |||
| ZG-WDS70/WDS22/WDS8T | Standard mode | 16 | OMRON standard white alumina ceramic object | |
| ZG-WDS3T | Standard mode | 32 | OMRON standard mirrored object | OMRON standard diffuse reflective object |
2.The tolerance for an ideal straight line obtained by determining the average height of an OMRON standard measurement object for the beam line. The CCD standard mode is used. Linearity varies depending on the measurement object.
| Mode | Measurement object | |
| Regular reflective | Diffuse reflective | |
| ZG-WDS70/WDS22/WDS8T | OMRON standard white alumina ceramic object | |
| ZG-WDS3T | OMRON standard mirrored object | OMRON standard diffuse reflective object |
3.A value attained by using an aluminum jig to secure the distance between the Head and the measurement object. The CCD standard mode is used.
4.Defined as 1/e2 (13.5%) of the center light intensity. This may be influenced when light leakage also exists outside the defined area and the reflectivity of the light around the measurement object is higher than that of the measurement object.

Note:
1.The image input periods listed here are for fixed/auto sensitivity. The image input period will be longer for multi-sensitivity or other settings. Use the eco monitor in RUN mode to determine the actual image input period.
2.You can use input signal lines to switch between banks 1 to 4. You can use serial communications commands or the Controller keys to switch between banks 5 to 16.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
