Aluminum-detecting Proximity Sensor E2EY CSM E2EY DS E 5 1 A Proximity Sensor for Aluminum, Brass and Other Non-ferrous Metals. Iron Is Not Detected. Non-ferrous metals, such as aluminum and brass, are detected. * Ferrous metals, such as iron and nickel, are not detected. * Aluminum foil, however, cannot be detected. Be sure to read Safety Precautions on page 4. Ordering Information Sensors Refer to Dimensions on page 4.
