Field of View and Reading Distances

The following maps show the field of view of the DataMan 360 series readers. Reading distance values are also provided for 1-D and 2-D example code distances.

For the C-mount (or other non-Cognex) and S-Mount lenses, the focal length of the lens, focus setting, and aperture setting determine the field of view and reading distance.

Note: Due to tolerances, ranges can vary by +/- 5 % from unit to unit.

Reading Distance and Field of View (DataMan 360 Readers with a 10.3 mm Liquid Lens)

The map below shows the field of view (FoV) of the DataMan 360 readers with a 10.3 mm lens (with or without a liquid lens).

The FoV values are shown as follows:

  • outer: DM362, DM363
  • inner: DM360

The reading distances for the DM360 and DM362 readers are the same. DM363 features a higher resolution and more pixels in about the same sensor size.

The following table shows the FoV widths in mm at various distances.

Distances in mm DM360 DM362 / DM363
50 26 42
100 46 74
150 66 106
250 106 171
500 207 332
