Contrast sensors
KTS Core

Universal contrast detection in modern housing

Your Benefits

  • High switching frequency for use in quick machine processes with high switching accuracy requirements
  • Display and flexible sensor settings for easy sensor handling and user-friendly operation
  • High gray line resolution enables the detection of very small contrast differences and high-gloss materials - high process stability and fewer downtimes
  • Various teach-in processes for ideal sensor and process setting in different applications
  • Manual switching threshold adjustment supports stable material detection and individual sensor adaption to different contrasts


Universal contrast detection in modern housing

High performance for universal application in a range of applications: The new KTS Core in modern design with white LED or RGB LED and VISTAL® housing impresses with its switching frequency and gray line resolution, different teach-in variants and manual switching threshold adjustment. A response time of 20 µs and a jitter of 10 µs ensure reliable and accurate detection of contrast differences, e.g. in print marks, even on high-gloss materials. Thanks to various teach-in processes and manual switching threshold adjustment, commissioning is more flexible and detection more stable. The KTS Core detects even the smallest differences in contrast and is therefore well-suited for use in a wide range of applications.
