E2A, 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

  • Ensures a sensing distance approximately 1.5 to 2 times larger than that of any conventional OMRON Sensor.
  • Problems such as the collision of workpieces are eliminated.
  • Full range of standard sizes (M8, M12, M18 and M30; both long and short barrels)
  • Modular construction simplifies
