Benefits of the E3AS-HL Series

The E3AS-HL sensors give manufacturers peace of mind by ensuring consistent detection, enhancing flexibility, and minimizing maintenance needs.

Stable detection amid target variation

The E3AS-HL Series uses a CMOS image array to achieve reliable detection levels even when the target is small, uneven, has differences in reflectivity or color, or is transparent.

Support for flexible production

Foreground and background suppression enhance the ability of the CMOS image array to selectively differentiate targets from bright backgrounds or surrounding parts and targets.

Ease of use and maintenance

The single teach button and a bright OLED display improve ease of use with set value and teach point confirmations, while IO-Link enables real-time condition monitoring and remote configuration.aximiz...

How the E3AS sensors keep detection stable as objects vary

Stable detection can be a challenging proposition on flexible manufacturing lines. Here are a few ways Omron’s technology makes it work.

  1. Stable detection of uneven objects. E3AS-HL Series line beam sensors mitigate surface issues like unevenness by “averaging” variable contours of the surface to achieve stable detection.
  2. Reliable detection of small targets. The E3AS-HL series uses a small spot beam (~2.5mm wide) to reliably detect small objects out to 500mm.
  3. Single unit detection of transparent objects. With the CMOS technology behind the E3AS-HL, the need for a reflector is eliminated improving installation time and removing space considerations for reflectors
  4. Stable detection for flexible manufacturing lines. With Omron’s sensors, the influence of color patterns and gloss is minimized allowing users to standardize on a single product regardless of changes in the production line.

Simple teach mechanism and IO-link make setup easier than ever

The E3AS-HL series features the same single teach button of the E3AS-F and adds an OLED display to make status information readily accessible at all times. Teaching can also be done remotely via IO-Link. The sensors enable a variety of teaching options, including the following:

  • Two-point object/background teaching
  • Background suppression teaching to ignore objects or backgrounds behind the object
  • Foreground suppression to ignore objects in front of the object
  • Window setting for using BGS and FGS together

All teach options can be implemented via IO-Link and can be done with measurement data that can be retrieved or input into the device.
