Double-slit Optical Design


P-opaquing Function


P-opaquing function uses double refraction to cut out polarized components with OMRON’s unique polarization filter.


Narrow beam


Narrow beam diameter of minimum 2.5 mm


Tache visible

The visible spot in the Reflector lets you easily adjust the height of the optical axis for detecting the different heights of workpieces and reduces time required for adjustment.


Easy to See Indicators

Large, easy-to-see light and stability indicators let you easily check operation from any angle.



  • Withstands harsh environments with high temperatures and high water pressures.
  • IP69K Degree of Protection.

IP69K is defined in DIN 40050 Part 9 of the German standards for protection against high temperatures and high water pressures.


Resistance to Detergents Certified by Ecolab

Third-party certification has been received from the Ecolab company in Europe for applications in water-washed environments.
