Features
  • M6 and M4 nut-type mounting: FNU-R5NYBC uses an M6 sensing head, while FNU-R8YBC uses a more compact M4 head for different installation requirements.
  • Single-side reflective sensing: Transmitting and receiving optics are located on the same sensing side, eliminating the need for an opposing fiber head.
  • Up to 1,000 mm detection: FNU-R5NYBC provides up to 630 mm detection, while FNU-R8YBC reaches up to 1,000 mm.
  • Narrow-view stable detection: A concentrated sensing area increases the received-light difference when a target enters the detection zone.
  • Reduced cable snagging: The fiber exits directly from the side of the sensing head, reducing protrusion and cable snagging inside equipment.
