Features

Achieves angled illumination

The LNDG series enables detection of bumps and subtle vertical wrinkles, which were difficult to detect with conventional line sensor lights, in paper or non-woven fabric that disperses light.

Other features

  1. Fan-less (Natural air cooling)
  2. Error detection support
  3. Emitting surface 300 to 3,000 mm long (can be made in units of 100 mm)
Error detection is a function included with the PSCC series, the recommended Control Units.

Bumps and subtle vertical wrinkles can be detected

Applications

Inspections for vertical wrinkles in paper labels

Example configuration

Achieves angled illumination using an original optical design. This is a line sensor light perfect for detecting moving-direction bumps and subtle vertical wrinkles.

LNDG series

Select a Light Unit that is longer than the width of the workpiece.

The LNDG-series Light Unit emits light at an angle to enable detecting "vertical wrinkles and bumps." When you select a Light Unit, select one that is at least 200 mm longer than the width of the workpiece to be inspected. We recommend a illuminating distance of 50 mm to obtain sufficient illumination.
