Welding Proximity Sensor

E2EW Series

DC 3-wire

Stable detection in lines containing both

aluminum and iron

• Equivalent sensing distances for both iron and aluminum 1

• Enables common design for lines with both iron and aluminum 1

• The exceptional sensing range 2, which means fewer false

detections and thereby fewer unexpected stoppages.

• OMRON’s unique fluororesin coating technologies enable long-

lasting spatter resistance 4, eliminates the need to replace for 10

years 3.

• Durable full metal body to reduce unexpected

downtime

• 2-output (NO+NC) models and models with IO-Link 1 are also

available.

• Laser printed information (sensing distance on the sensor head,

model on the cable, and model on the metal part of the connector

model) reduce errors during sensor replacement. 5

•

Weld field immunity cancels pulse noise from magnetic fields. 1

• UL certification (UL60947-5-2) and

CSA certification (CSA C22.2 UL60947-5-2-14)

1. PREMIUM Models only.

2. Based on November 2020 OMRON investigation.

3. This value assumes that the sensor operates 10 hours a day in an arc welding

environment and is cleaned once a month (12 times a year).

If our previous model (E2EF-Q) needs to be replaced once every 3 times it is cleaned, the E2EW-Q Proximity Sensor needs to be replaced

once every 180 times it is cleaned. This means that there is no need to replace the E2EW-Q Proximity Sensor for 10 or more years.

4. Models with spatter-resistant coating only.

5. Models without spatter-resistant coating only.
