Omron E2EY Aluminum Detecting Proximity Sensor 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.
Omron E2EY Aluminum Detecting Features
- 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.
