The SICK color mark sensor detects a wide range of labels, even if there are subtle differences in the background color, and the processing speed is fast. Automatically adapts to wavelength and is able to detect small differences in grayscale values, regardless of the mixed color of the label and background.
Contrast sensors from SICK are often used to detect spots on specific color marks or objects by comparing them with non-color mark areas, rather than measuring color directly. The sensor is actually a reverse device, where the light source is mounted perpendicular to the target object, and the receiver is mounted at an acute angle to the object, so that it only detects the scattered light from the target object, thus avoiding the sensor from receiving the reflected light directly, and the beam can be focused very narrowly. Both incandescent and monochromatic light sources can be used for mark detection.
Sensors based on incandescent lamps detect color with a colored light source that emits a variety of colors, including infrared, so sensors with this light source can detect small changes in color over a wide range. In addition, the detection circuitry of incandescent lamp sensors is usually very simple, so they can achieve extremely fast response times. However, incandescent lamps do not allow vibration and prolonged use, so they are not suitable for occasions with severe shock and vibration.
Contrast sensors that use a monochromatic light source (i.e., green or red LEDs) do not detect color by their principle, but by detecting the difference in the amount of reflection or absorption of the light by the color mark compared to the surrounding material. Therefore, the identification of colors should strictly correspond to the spectral composition of the target irradiated.
In monochromatic light sources, green LEDs (565 mm) and red LEDs (660 mm) have their own strengths. Green LEDs last longer than incandescent lamps and are more sensitive than red light sources over a wide range of colors. Red LEDs respond to limited color combinations, but they can detect at a greater distance than green LEDs. Usually, the detection distance of the red light sensor is 6-8 times that of the green light sensor.
