  • Multi-functional sensor adjustment for individual sensor adjustment
  • Excellent contrast resolution and a large dynamic range for good performance on complex materials
  • High flexibility thanks to a range of teach-in processes
  • Integrated color mode - stable detection even with complex color differences
  • Job storage in sensor - flexible process design and format change
  • Diagnostics and visualization as well as easy format change via IO-Link


Innovative TwinEye-Technology for better contrast detection

Outstanding performance for a variety of applications, even with difficult framework conditions: The new KTS Prime with modern design, high-precision RGB LED and VISTAL® housing impresses with TwinEye-Technology, color mode, high switching frequency, excellent gray line resolution, 7-segment display and IO-Link. The response time of 10 µs and a jitter of 5 µs ensure accurate detection of contrast differences, even at high machine speeds. Thanks to various teach-in processes, integrated color mode and variable sensor adjustment, commissioning is more flexible and the processes more stable. The KTS Prime provides additional diagnosis and analysis data via IO-Link. The new KTS Prime - it can easily do more.
