 E2EY, Omron-Aluminum-detecting Proximity Sensor

These Proximity Sensors use high-frequency oscillation. They resist heat, chemicals, and water better than Rectangular Sensors. They are available in both shielded and unshielded models. OMRON Sensing Components detect, measure, analyze, and process various changes that occur on productions sites, such as changes in position, length, height, displacement, and appearance. They also contribute to predicting and preventing future events.


  • Non-ferrous metals, such as aluminum and brass, are detected. *
  • Ferrous metals, such as iron and nickel, are not

* Aluminum foil, however, cannot be detected.
