Photoelectric Sensors detect photo-optical workpieces. OMRON provides many varieties of sensors, including diffuse-reflective, through-beam, retro-reflective, and distance-settable Sensors, as well as Sensors with either built-in or separate amplifiers.

Seperate Amplifier

With these Photoelectric Sensors, the Amplifier and Sensor Head are separated to enable downsizing and facilitate adjustment.


Ideal for Applications That Cannot Be Handled with Fiber Sensors or Photoelectric Sensors

High precision laser sensor with separate amplifier

The separate amplifier laser sensors feature a comprehensive range of sensing heads with variable spot and advanced CMOS sensing heads for high precision positioning and demanding applications.

  • High detection stability independent from color or surface structure
  • Lens attachments for line beam applications
  • Easy installation due to adjustable focus and smart tune functions
  • Sensor heads with up to 1.2 m sensing distance cover a wide range of applications
  • High speed network connectivity to EtherCat fieldbus

Built-in Amplifier

With these Photoelectric Sensors, the amplifier is built into the Sensor Head.


High detection capabilities for stable detection of a wide range of transparent workpieces in the food and packaging industries, including glass bottles, PET bottles, films, and trays. You can increase equipment operating rates and reduce commissioning and maintenance work.

  • Double-slit optical design ensures reception of only parallel light to stabilize detection.
  • P-opaquing function ensures attenuation of 70% even on films with little difference in light levels.
  • Narrow beam enables incident light with gaps as narrow as 3mm.
  • Visible spot in the reflector lets you easily adjust the optical axis.
  • Large indicators are easy to see from any angle.
  • IP69K water resistance withstands harsh environments.
  • Resistance to detergents certified by Ecolab.
