Contrast sensor works anywhere
The KTM Inox contrast sensor from Sick features high grayscale resolution and is integrated into a new, rugged stainless steel housing.
The optimized OES4 ASIC technology, combined with a response time of 35μs, ensures reliable and accurate detection of contrast marks, even on glossy materials.
The various teach-in methods (dynamic, static, and switching threshold close to mark) ensure greater f lexibility during commissioning.
The integrated IO-Link interface can be used to access the parameter settings. This speeds up and simplifies format changes.
The KTM Inox reliably detects marks even in conditions with weak contrast ratios and is therefore ideal for use in a wide range of applications, even in harsh environments during intensive cleaning. Black and white or colour, matte or shiny – with the new ASIC in the KTM Inox contrast sensor, print marks are reliably detected on a wide range of materials.
This improved performance is particularly beneficial for shiny materials such as high-gloss foils and for low contrast levels. For example, the sensors can deal with weaker saturated print marks that arise as a result of scanning or due to the use of low contrast and pale colours.
Particularly helpful for processes that involve high throughput speeds in packaging machinery, food and beverage and the graphics industry, this contrast sensor can quickly and reliably detect the signal variation when the contrast mark has been passed, therefore ensuring high positioning accuracy even at high throughput speeds.
In addition to differentiating between black and white, this sensor can also take a range of shades into account. Its fine resolution of approximately 20 gray tones guarantees that even minimum levels of contrast are detected. This extends the application range of the KTM Inox contrast sensor to also include challenging applications.
With IO-Link technology format changes can be handled quickly and easily by retrieving the parameter settings of jobs that have already been completed from the control system‘s memory.
