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

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.
