Contrast sensors
KTM Prime

Your Benefits

  • Small housing allows for installation even where space is limited
  • Powerful, fast contrast sensor ensures high machine availability
  • Three-color LED technology allows for a reliable process, with contrast marks detected even in conditions with weak contrast ratios or on glossy materials
  • Various teach-in methods enable more flexible commissioning
  • Long service life, even in harsh environments, thanks to stainless-steel housing; as a result, excellent plant availability and low spare parts costs
  • Enhanced diagnostics and visualization as well as quick and easy format changes via IO-Link


Top performance for universal, space-saving use in the packaging industry, even in adverse conditions: The new KTM Prime contrast sensor from SICK features high grayscale resolution and is integrated into a small, tried-and-tested housing that is also available in stainless steel. The optimized OES4 ASIC technology and a response time of 35 µs ensure reliable and accurate detection of contrast marks, even on glossy materials. The various teach-in methods ensure greater flexibility during commissioning. The integrated IO-Link interface can be used to access the parameter settings. A KTM Prime laser variant with a sensing distance of up to 250 mm is available for long-distance applications.
