Business Challenge 

**If we respond to packaging trends, the number of false detection with color mark sensors will increase, reducing productivity...** 

More and more people working with color mark detection in the field are calling for the following: 

“I want stable detection of aluminum va **material por deposition** and other glossy packaging.” 

“I want stable detection of colorful packaging with little color difference.” 

“I want stable detection of packaging even if the lot changes.”

## OMRON’s New Color Mark Sensors 

## **Offer Stable Detection** 

## **of Both Glossy and Colorful Packaging.** 

## It therefore does not reduce the operation rates of production facilities. 

The Sensors can accurately detect color marks on glossy and colorful packaging, which have been troublesome for conventional systems. 

They also help reduce the number of troubleshooting requests made to packaging machine manufacturers—without any decrease in the operation rate due to equipment stoppages caused by false detection.

“I want stable detection of aluminum vapor deposition material and other glossy packaging.” 

The intensity of the light received by the sensor from highly-reflective glossy packaging is too strong, so there is not enough difference in incident levels to perform color mark detection (i.e. saturation, Fig. 1). 

The angle needs to be finely adjusted to avoid saturation and allow the sensor to detect the mark. However, if the sensor is tilted too much, detection will become unstable as the incident level decreases (Fig. 2).

No Saturation Even with 99% Reflective Optical Mirrors 

## **High Dynamic Range (Wide Incident Light Range)** 

## **Color Mark Photoelectric Sensor (E3S-DC):** 

The incident light range in which no saturation occurs—no adjustment required 

The included high luminance RGB three-color LED light emitting element drastically improves the light intensity. Meanwhile, Smart Noise Reduction technology in the Fiber Sensor is applied to reduce the amount of noise, resulting in a high dynamic range where the Sensor is not saturated even when detecting a mirror surface—without having to make any light intensity adjustments. 

## **Color Fiber Amplifier Unit (E3NX-CA):** 

The optimal light intensity—with just two button presses 

The high luminance white LED and Smart Noise Reduction technology work together to increase the light intensity and reduce the amount of noise. These have made it possible to expand the light intensity adjustment range for the emitter and receiver to 1/100x and 1/3x respectively, resulting in a high dynamic range four times that of conventional products. You can automatically adjust the optimal intensity by just 

pressing a button once with a mark and once without it.

With designs becoming more colorful, there are times where there is little difference in color between the color mark and the design elements (background). When color differences are subtle, the S/N ratio*1 required for detection cannot be obtained, and the color mark cannot be detected (Fig. 1). 

- *1 The ratio of incident levels at which a workpiece is and is not detected. For example, if this is 1,000 when detecting the workpiece and 100 when not detecting the workpiece, the S/N ratio is 10:1. The higher the S/N ratio is, the more stable the detection becomes.

## **From Single Wavelengths to Color Sensing** 

The wavelength ranges for red, green, and blue are narrow, and combinations with other colors cannot be detected with RGB single-color light source sensors (Fig. 2). For the new Color Mark Sensors, the Photoelectric Sensor uses RGB three-color LEDs as the light source, and the Fiber Sensor uses a white LED that has a broad wavelength range. Color sensing makes stable detection possible—even for those color combinations that would be difficult using single wavelengths.

## “I want stable detection of packaging even if the lot changes.” 

There are cases where colors of packaging materials vary from lot to lot. If the parameters are not changed, this could result in equipment stoppage caused by false detection. In such a case it can be difficult to determine the cause of the problem—resulting in time lost due to troubleshooting and a notable decrease in productivity.

## Visualization of Color Variation 

## **RGB Data Transmission Function** 

RGB information for color marks and backgrounds for each lot is transmitted to a host and quantified. This information is then managed in a database, making it possible to set optimal thresholds and identify causes quickly if a problem occurs. 

Until now, setting the threshold during commissioning required the knowledge of an expert. Now it is During commissioning [Ld possible to get the optimal setting just by registering the RGB ratio of the packaging. 

When the Sensor makes false detection, values can be checked to determine whether color variation from During maintenance [ lot to lot in packaging material has occurred, making it easy to identify what has caused a problem and to then resolve it.

## **Further Information** 

## **Test Parameter Support Function**[*1] 

The test parameter support function allows users to determine whether or not detection is possible for designs in the prototyping stage. Package designers and production engineers use quantified RGB digital data to discuss the designs, which allows them to reach a quick decision on which design to use—and helps shorten lead times from design to production line commissioning.

## ~~PT~~ **Precautions for Correct Use** 

1. Note that the water-resistant function is impaired if installing the Photoelectric Sensor by hitting it with a hammer and so on. 

2. Be sure to tighten the external lens until it reaches the chassis. 

3. If the Sensor wiring is placed in the same conduits or ducts as high-voltage or high-power lines, inductive noise may cause malfunction or damage. Wire the cables separately or use a shielded cable. 

4. To extend a cable in the standard I/O mode, use a cable of 0.3 mm[2] or more and keep the length 100 m or less. Keep the length 20 m or less if using the Sensor in the IO-Link mode. 

   6. If a commercial switching regulator is used, ground the FG (frame ground) terminal. 

   7. The Sensor will be able to detect objects 100 ms after the power supply is tuned ON. Start using the Sensor 100 ms or more after turning ON the power supply. If the load and the Sensor are connected to separate power supplies, be sure to turn ON the Sensor first. 

   8. Do not press the button with anything sharp such as a screwdriver because it might be damaged. 

   9. Output pulses may occur when the power supply is turned OFF. We recommend that you turn OFF the power supply to the load or load line first. 

5. Apply a screw tightening torque of 2.0 N·m or less.
