Features
  • Coaxial reflective sensing: Transmitting and receiving light are aligned along the same sensing direction for reflective detection from one side of the target.
  • Narrow-view stable detection: The concentrated sensing area increases the received-light difference when a target enters the detection zone.
  • M6 and M3 head sizes: FNU-X7YBC uses an M6 nut-type head, while FNU-X8YBC uses a smaller M3 head for compact installations.
  • Up to 1,170 mm detection: FNU-X7YBC reaches up to 1,170 mm, while FNU-X8YBC provides up to 440 mm detection.
  • Reduced cable snagging: The fiber exits directly from the side of the sensing head to reduce protrusion and cable snagging inside equipment.
