E2E3, Omron-Cylindrical 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.

Features and Benefits

  • CENELEC triple-distance
  • Normally open (NO), and normally closed (NC) mod- els are
