Features
  • Compact side-on design: The slim and lightweight housing saves installation space, while the flat lens helps reduce dust and dirt accumulation.
  • Four sensing methods: The lineup includes through-beam, polarized retroreflective, diffuse reflective, and convergent reflective models for different target and installation requirements.
  • Detection up to 10 m: GN-T10CR models provide a 10 m through-beam sensing range, with additional 7 m through-beam, 1.3 m retroreflective, and multiple reflective ranges.
  • NPN or PNP outputs: Major sensing configurations are available with NPN or PNP open-collector outputs and selectable Light-ON/Dark-ON operation.
  • Cable or M8 connection: Standard attached-cable models and M8 connector versions with the -J suffix are available throughout the lineup.

Specification notes

  • Model selection is primarily based on sensing method and range: through-beam models reach up to 10 m, polarized retroreflective models reach 1.3 m, diffuse reflective models cover 70, 300, and 400 mm, and convergent reflective models cover 3–30 mm or 1–40 mm.
  • Through-beam models support GNP1, GNP2, GNP3, and GNP5-1 pinhole plates to reduce detectable object size or operating width. Sensitivity adjustment can further support small or nearly transparent objects.
  • Red LED through-beam models support GN-PFA and GN-PFB interference prevention filters. With the filters installed, the detecting distance is 5 m.
FAQ
