Special Sensors

Color? Luminescence? Contrast? Everything from a single source – Everything compatible for you

Our broad product line of scanners includes, in addition to various sensor tech- nologies, various designs and housing materials. Thus, with Leuze electronic, you will find the right solution both for all materials that need to be detected as well as for diverse installation situations and environmental conditions. A big plus point of the Leuze electronic product line is the compatibility of the individual systems with respect to both mounting as well as to configuration and electrical  connection.

Color sensors - CRT - precisely measure and compare color values and make decisions

Color is an important characteristic for the control and monitoring of auto- mated processes. These sensors detect the color of an object and compare it within specified tolerances with a taught reference value. Decisive here is, above all, a fast and simple teach process, a high processing speed and the reliable detection of even very small differences in color.

CRT442 - Small but powerful

  • 12.5 mm scanning range;
  • Very small plastic construction  Simple teach-in of the reference color One color channel;
  • Adjustable color tolerance;
  • 1.5 kHz switching frequency M12 connector.

CRT20B - The flexible standard

  • 12.5 mm or 60 mm scanning range;
  • Very robust metal construction Simple teach-in of up to four reference colors;
  • Sensitivity adjustment following teach-in;
  • 1/4 color channels;
  • Color tolerance separately adjustable per color channel;
  • Switching frequency up to 6 kHz;
  • Extensive configuration options;
  • Turnable M12 connector.

Luminescence scanners - LRT - Reliably detect visible and invisible luminescent materials and marks

These luminescence scanners are energetic diffuse reflection scanners that illuminate luminescent materials by means of their special UV transmis- sion light. The resulting visible light is detected by the luminescence sensor. Some of these luminescent materials are invisible and are available in a variety of solid and liquid forms. These can also be used to apply markings that are invisible under normal lighting conditions.

LRT8 - Reliability doesn't need to be any larger than this

  • Scanning ranges up to 200 mm;
  • Very compact metal construction;
  • 1.5 kHz switching frequency;
  • Sensitivity adjustment via potentiometer;
  • Turnable M12 connector Filter variants.

LRT440 - Ahigh-performanceall-rounder

  • A high-performance all-rounder;
  • Scanning ranges up to 300 mm;
  • Very compact metal construction;
  • Switching frequency up to 6 kHz;
  • Sensitivity adjustment via two buttons;
  • M12 connector;
  • Filter variants.

Contrast scanners - KRT - Reliably detect minimal gray value differences with extremely fast response time

In many areas, the fast and reliable detection of gray value differences on a wide range of surfaces is of decisive importance. Operating on the reflec- tion principle, these sensors detect even the smallest differences and, with the simple teaching process and their unique additional features, such as YellowBoost for preventing the "yellow hole" and the innovative EasyTune for intuitive fine adjustment of the switching threshold, are the most efficient and reliable choice.

KRT3B - So small and yet still full-featured

  • Plastic housing;
  • Scanning range 14.5 / 60 mm;
  • RGB, white or laser light;
  • Various teach-in processes;
  • Teach-in with switching-threshold adjustment;
  • Switching-threshold correction via EasyTune;
  • Min. response time 50 µs;
  • Switching frequency up to 10 kHz;
  • Remote teach and keyboard lockout Pulse stretching;
  • IO-Link interface.

KRT55 - Whenever  absolute cleanliness is needed

  • Stainless steel housing AISI 316L;
  • Scanning range 13 mm;
  • RGB or white light;
  • Various teach-in processes;
  • Teach-in with switching-threshold adjustment;
  • Switching-threshold correction via EasyTune;
  • Response time 50 µs Switching frequency 10 kHz;
  • Remote teach and keyboard lockout;
  • Pulse stretching;
  • IO-Link interface.

KRT20B - All-rounder with unique features in the Standard or Advanced version

  • High-strength plastic housing with metal threaded sockets;
  • Scanning range 13.5 mm;
  • RGB or white light;
  • Various teach-in processes;
  • Teach-in with switching-threshold adjustment;
  • Switching-threshold correction via EasyTune;
  • Min. response time 50 µs;
  • Max. switching frequency 10 kHz;
  • Remote teach and keyboard lockout;
  • Pulse stretching;
  • IO-Link interface.
