Types of Omron E3S photoelectric sensors

Applications for omron photoelectric sensors include packaging lines, conveyor systems, factory automation, and access control.

  • Reflected beam sensors: These sensors use light reflection from objects to detect them. They are frequently employed to find irregular or tiny things. Popular models: E3S-B, E3S-D, E3S-F.
  • Direct-beam sensors: By breaking the light beam, these sensors are able to detect objects. They are often used to detect large or flat objects. Popular models: E3S-N, omron e3s c, E3S-G.
  • Diffuse reflection sensors: These sensors detect objects by detecting scattered light. They are often used in difficult or dirty environments. Popular models: E3S-K, E3S-H, E3S-R.
  • Retroreflective sensors: By reflecting light back to the sensor, these omron retro reflective sensor pick up objects. They are often used to detect objects at a great distance. Popular models: E3S-L, E3S-E, E3S-S.

Factors to consider when choosing a detector

  • The type of object you want to detect: Different types of sensors are better suited for different objects.
  • Reflected Rays: These sensors detect objects by bouncing light off of them. They are frequently employed to find irregular or tiny things.
  • Direct beams: These sensors use beam interruption to identify objects. They are frequently employed to find big or flat things.
  • Diffuse Reflective: These sensors detect objects by detecting scattered light. They are often used in complex or dirty environments.
  • Retroreflective: By reflecting light back to the sensor, these sensors pick up objects. They are often used to detect objects at a great distance.
  • The distance at which you want to detect an object is: Some sensors have a longer range than others.
  • The environment in which the detector will be used: Some sensors are better suited for difficult or contaminated environments.
  • Size and shape of the sensor: Some sensors are more compact than others.
  • Price of the sensor: Omron photoelectric sensor price can vary depending on their features.

Popular models of Omron E3S photoelectric sensors:

  • E3S-B, E3S-D, E3S-F: Reflected beam sensors
  • E3S-N, E3S-C, E3S-G: Direct beam sensors
  • E3S-K, E3S-H, E3S-R: Diffuse reflective sensors
  • E3S-L, E3S-E, E3S-S: Retroreflective sensors

Steps to select an Omron E3S photoelectric sensor
