Now that the correct sensing method is determined for any application, these are the major features within the E3Z series that help it stand out. Firstly, it has an impressive IP rating of IP67 which means it can be used in washdown environments necessary for food and commodity manufacturing, as well as dusty and dirty environments of automotive. The E3Z includes two trimpots, one which adjust the sensitivity of the light, making it simple to teach the sensor to the object and another trimpot to quickly switch the logic of the output from light-on to dark-on. In addition, the large indicator light above the sensitivity adjuster trimpot further eases setup as it helps quickly confirm the teach has been successful or if the sensor is stable and properly aligned. Finally, the E3Z series includes models that are IO-link enabled. IO-link is a powerful tool which allows for remote monitoring so maintenance actions may be taken to fix a sensor before it fails. For example, if there is too much dirt and oil buildup that the sensor may no longer reliably detect and requires a wash-down. This practice is also referred to as "predictive maintenance". Moreover, IO-Link makes setup and replacement faster and easier than ever before.
