Welding Proximity Sensor E2EW Series DC 3-wire Stable detection in lines containing both aluminum and iron 1 Equivalent sensing distances for both iron and aluminum 1 Enables common design for lines with both iron and aluminum 2 The exceptional sensing range , which means fewer false detections and thereby fewer unexpected stoppages. OMRONs unique fluororesin coating technologies enable long- 4 lasting spatter resistance , eliminates the need to replace for 10 3 years . Durable full metal body to reduce unexpected downtime 1 2-output (NO+NC) models and models with IO-Link 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 For the most recent information on models that have been certified for safety standards, refer to your OMRON website. 5 model) reduce errors during sensor replacement. 1 Weld field immunity cancels pulse noise from magnetic fields. UL certification (UL60947-5-2) and Be sure to read Safety Precautions on page 23. 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.

When embedding the Proximity Sensor in metal, refer to Influence of Surrounding Metal on page 24. 2. Models with 5-m cable length are also available with5 suffix. (Example: E2EW-X7B1T12 5M) Note: 1. Models in are equipped with IO-Link (COM3). For IO-Link (COM2), select a model number with the format ofE2EW-X (Example: E2EW-X7B1D12 2M). Operation mode NO can be changed to NC via IO-Link communications. 2. IO-Link is not supported for NC-type PNP outputs or all types of NPN outputs. 2
