Finally, the E3AS-F series contains important features that help this sensor excel in all industrial automation environments and scenarios. To start with, the E3AS-F sensors include a single teach button, making it extremely easy to set up and no additional training should be necessary. In addition, the E3AS-F has a small footprint and standard mounting so it can be retrofitted into existing equipment or machinery, cutting down installation time. The highly visible indicators paired with the IO-Link functionality cut down on problem identification and machine downtime, as users can determine the cause of shutdown quickly and take swift action. Finally, the lens of the E3AS-F includes an anti-fouling coating on the sensor. The coating is exceptional at instantly shedding any water, dirt, and grime that would normally adhere to the sensing surface that would prevent reliable detection.
