Omron E2EW Proximity Sensor

Omron E2EW Proximity Sensor

Omron E2EW Proximity Sensor offers equivalent sensing distances for both iron and aluminum. This means that a common design can be adapted to detect the setting of both iron and aluminum workpieces in welding processes.

It also boasts an exceptional sensing range, which means fewer false detections and thereby fewer unexpected stoppages. It is equipped with a function, which effectively cancels the pulse noise of the current magnetic field generated during welding

Omron E2EW Proximity Sensor Features

  • Equivalent sensing distances
  • for both iron and aluminum
  • Enables common design for lines with both iron and aluminum
  • Durable full metal body to reduce unexpected stoppages.
