Width - Car body

The sensor checks the correct width between different parts of the car body.

Bottom PCB board

The sensor checks the warpage of a PCB board to avoid soldering or connection defects.

Area glue bead

The sensor checks the area (shape) of the glue to control the continuous motion of a robot.

Position – Sheet

The sensor checks the wandering of paper over time in order to detect drifts.

Angle – Seat

The sensor checks the differences of seat angles. The controller allows you to calculate various angles via the definition of additional tasks.

*1 Obtained by setting an Omron standard measurement object at the measurement center distance and determing 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.The minimum resolution of the ZG2-WDS8T/WDS3VT is 0.25 ƒÊm, even when the average number of operations is increased. Resolution does not go any lower.

*3 A value attained by using an aluminum jig to secure the distance between the Sensor head and the measurement object. The CCD standard mode is used.

*4 Defined as 1/e 2 (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.

1. Setup support software for PC is attached

2. The image input periods listed here are for fixed/auto sensitivity. The image input period will be longer for multi-sensitivity, high-speed multi-sensitivity, or other settings. When the high-power mode is ON, the shortest image input period is 95 ms regardless of the setting of the CCD mode. Use the eco monitor in the RUN mode to determine the actual image input period.

3. when ZG-RPD is mounted

4. The controller link unit is necessary for linking.

5. Data is saved in the memory of the main unit during logging. The data is automatically saved in a memory card after logging is completed. The maximum number of logging differs according to set conditions. For details, refer to the Users Manual.

6. Measurement values for 65,000 measurements can be saved even when two sensor controllers are connected and each performs eight tasks.

7. The value is the maximum number achieved in the following conditions:
• One sensor controller performs one measurement task.
• Either profiles or measurement values are logged.
