Contrast sensors gauge how often light the target reflects to distinguish between two hues. Most of the time, the difference between the target and background colors correlates to the shift in contrast. Contrast sensors are frequently employed in packaging and printing equipment to detect print marks.
Contrast Sensor Technology Leaps Forward with the SICK KTS/KTX. The KTS/KTX family of contrast sensors, introduced by SICK, offers a potent next-generation technology that sets new standards in dependability, accuracy, and adaptability for print, labeling, converting, and packaging applications.
In sheet- and reel-fed manufacturing, even under difficult circumstances, the SICK KTS and KTX family of monochrome and color contrast sensors achieve unprecedented levels of detection accuracy and switching frequency speed. The sensors have small, lightweight housings made of durable ABS, IO-Link data transfer, and an intuitive onboard display for quick setup and enhanced diagnostics.
The sensors include SICK’s ground-breaking Twin-Eye Technology, which has a larger sensing distance tolerance and superior depth of field for improved contrast detection. Greater grey-scale sensitivity allows for even better detection of registration marks in monochrome or color, even on very glossy packaging.
Customers can select various degrees of functionality to meet their needs from the product’s variety of “core” and “prime” options. The KTS and KTX are easily able to handle up to 250 packs per minute and compensate for a high-speed flutter on reel-to-reel material edges thanks to their up to 70kHz switching frequency and down to 3-sec jitter rate (a level of performance never before attained).
Common applications like print mark detection and industrial labeling process management will instantly reap the benefits of the new technology’s enhanced process stability and reduced machine downtime. The increased variety of sensor alternatives now offers more possibilities for application areas like wafer detection, reel change management, and quality control.
The Global Contrast Sensors market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Baumer has launched its new range of contrast sensors in the market. The OC50 is a basic contrast sensor with the ability to detect even the smallest differences between a mark and the background with a jitter of greater than 25 microns. It features RGB LED, single-lens optics, and PMMA lenses all contained in compact plastic housing.
Leuze launched the smallest contrast sensor for the packaging industry. The KRT 3C can identify contrast differences in situations with limited installation space.
A new contrast sensor is available to identify contrast variations quickly and accurately when installation space is at a premium. The smallest contrast sensor for the packaging sector is the KRT 3C. To identify specific markings on objects during packaging procedures, contrast sensors have been created. These contrast markers can be found on labels, film, bags, blister packaging, and blister packaging.
With several transmitter colors (RGB light, white light, or laser-generated red light), the innovative compact contrast sensor of the 3C series can be utilized and adaptable for all typical color and gray value combinations. Even minute contrast variations are reliably and precisely detected, as are print traces on glossy materials.
The sensor was made to fit into small installation locations. It is the smallest contrast sensor available and has the most flexible mounting options thanks to its extremely small housing (11 x 32 x 17 mm).
The sturdy plastic housing provides protection levels IP67 and IP69K. The housing’s resistance to cleaning solvents frequently used in the packaging sector is confirmed by ECOLAB certification. The IO-Link interface makes it simple to complete all configurations for the integration and functioning of the sensors as well as for the case of format modifications for the products.
When it comes to the sensor system’s ability to reliably detect contrast markers, each application has various needs. The new KRT 3C contrast sensors use three different light types since the color of the produced light affects how reliably contrast markers are detected. Customers can choose the ideal light source in packaging or labeling procedures based on the kind of material and contrast marker color.
RGB (red, green, and blue) LED lighting is used for multicolor. Different color or gray value combinations can be accurately identified by automatically choosing the proper transmitter color. Films with a lot of color are especially well-suited for multicolor devices. If it’s necessary to discern colors and gray values from a reference gray value (with identical contrast resolution), a white light LED is employed. This offers increased dependability, especially when using contrast markers on glossy surfaces.
The best option for detecting minute markers and changes in distance is to use contrast sensors with a red light laser because they emit a very small laser light spot.
The new KRT 3C contrast sensors are easily calibrated using IO-Link, a teach button, or remotely using a cable and training. Sensors may be quickly added to an automation system using IO-Link. Integration is made easier by this kind of automation, which helps minimize production downtime to an absolute minimum. Through IO-Link, the new tiny contrast sensors may be set up, used, and maintained.
Easy format switching to another type of film or label by uploading the appropriate parameter set, including the teaching value, to the contrast sensor. When changing formats, there is no setup time or need to re-train the contrast sensor. Diagnostic and real-time signal information using the IO-Link interface, remote teaching, or locking of the teach button is quick and simple.
The range of teaching modes provides quick machine commissioning:
