With the spot beam, detection is unstable because the reflected light does not reach the sensor due to the surface of the workpiece. With the E3AS-HL line beam sensor, detection is less affected by the surface profile because the reflected light reaches the sensor from every part of the surface.<\/td>Detection tends to be unstable as color, pattern or reflectivity affect the detection distance. The E3AS-HL sensor is less likely to be affected by these, ensuring stable detection even when packaging materials change.<\/td><\/tr><\/tbody><\/table>

CMOS sensors with built-in lens alignment technology minimize the influence of material properties.

\u00a0
The material properties strongly affect the detection due to the smeared light spot obtained on the CMOS matrix as a result of the low accuracy of adjusting the position of the receiving lens.


\"\"

Material properties have little effect on detection, as the position of the receiving lens is automatically adjusted to the micrometer level to minimize the received light spot.

E3AS-L

\"\"


Readings can become unstable as the differential movement varies depending on the color of the part. The E3AS-L80 sensor can reliably detect a difference in level regardless of color, as its differential movement for black paper is 5%.

\"\"

When the workpiece is made of black paper with low reflectivity, detection may become unstable due to insufficient detection distance. The E3AS-L200 sensor can stably detect at the same distance regardless of color, as its detection distance for both white and black paper is 200 mm.

\"\"

OMRON’s unique LED package reliably detects low-reflective parts.
Overcomes space constraints, increasing design flexibility.
Retroreflective sensors are used to detect difficult-to-handle parts or where a long sensing distance is required.
Retroreflective sensor designs are time-consuming due to mounting space constraints as equipment becomes
complex and complex. On the other hand, the E3AS series allows for reflector-free designs.
E3AS-HL for multi-belt conveyors for curved surface parts

\"\"


Retroreflective sensors are used to detect the poorly reflective curved surfaces of cans and clear plastic bottles, but providing space for mounting reflectors on multi-lane conveyor lines is difficult.



\"\"

Stable detection of cans and plastic bottles without reflectors. The E3AS-HL sensor, a reflective model capable of detecting even the slightest change in the level or distance of incident light, can stably detect cans and plastic bottles without reflectors.

\"\"





Sensor algorithm detects minimal reflected light from curved surfaces. The E3AS-HL sensors, equipped with an FPGA, use the industry’s first measurement algorithm to perform high-speed light waveform acquisition at a frequency of 10,000 times per second and unique processing, which greatly increases their sensitivity. They amplify even the smallest amount of light to stably detect parts with shiny or uneven surfaces or parts with complex shapes from which it is difficult to receive reflected light.

E3AS-F for long distance measurement on converging and diverging lines

\"\"
No reflector is needed to design a long-range sensor that is not affected by color or material.

\"\"

Although retroreflective sensors are used for long-distance measurement in converging and diverging lines, it is difficult to find a place to mount reflectors.
The E3AS-F sensor, a reflective model with a long detection distance, does not require reflectors.
It is also less likely to be affected by color even at long distances.
TOF detects various details and measures distance
With the TOF method, distance is measured based on elapsed time rather than the amount of incident light received. Therefore, measurements are not affected by changes in the color or material of the detail.
This means that low-reflective details, such as black rubber, can be detected from greater distances.

Training allows for easy, fast and optimal adjustment
E3AS sensors allow almost anyone to easily set optimal settings using the training method, eliminating the need for re-adjustment. A single training button prevents inconsistent settings.
Easy and consistent setting of the optimal threshold level using the training button:

\"\"
Quick and easy setup, even when setting up a large number of sensors.
Adjusting sensitivity using the conventional dial method requires experience, finesse, and time, as the threshold level must be adjusted one by one.
With the E3AS series, simply press the learn button to automatically set the threshold level, allowing for quick and easy setup.

\"\"

Training for easy setup for transparent object detection
Previously, setting up transparent object sensors required the expertise of skilled workers, but now it can be done with just the push of a button.


\"\"

Easy to read and understand OLED display
Displaying the threshold level and detected value on the same screen makes setup easy. In addition, the wide viewing angle and display inversion allow field workers to easily see the display.

\"\"
Enhanced environmental resistance reduces line outages and maintenance frequency. When a sensor failure due to the environment causes a line stop during mass production, restarting can take a long time. With improved environmental resistance, the E3AS series will realize minimizing downtime and maximizing continuous operation time. A dirty sensor surface can cause false detection due to the principle of photoelectric sensors. The E3AS series has the industry’s first anti-fouling coating on the sensor surface, which prevents water droplets and paper dust from adhering to the sensor surface and protects the lens from fogging. This reduces false triggering.

Air Blower
The use of an air blower significantly reduces the frequency of false detections, as it prevents contamination of the sensor surface of sensors installed in confined, difficult-to-clean locations. It can be mounted to any photoelectric sensor with a mounting hole spacing of 25.4 mm, as well as to E3AS sensors.

\"\"
False detections due to environmental changes can be prevented.
The E3AS-HL sensors can operate in high ambient light conditions and have a mutual interference prevention function, reducing the frequency of false detections.
Operation in high ambient light
Prevention of mutual interference



The E3AS-HL sensors can operate in an ambient light of 20,000 lx, which is the best in its class, preventing malfunctions caused by camera lights or sunlight.
The mutual interference prevention function covers up to 4 devices, allowing for quick elimination of
false detections that occur when adding sensors.
