Through Beam

The light from a through-beam source unit is aimed directly at a separately mounted sensor/control unit. Objects between the two units break the light beam.

Because the light beam is focused, narrow, and not deliberately bounced off an object or a reflector, through-beam detection generally has a greater sensing range than reflecting units (retro-reflective or proximity) and greater freedom from false detection of shiny objects.

Notes

  • Unless rigid-wave-guides are used, the separate source and sensor must be carefully aligned during installation and kept in alignment during operation.
