Contrast Sensor, 3 Different Light Transmitters!
Leuze KRT 3B

Smallest in size, biggest in performance!
YellowBoost feature eliminates the 'yellow hole'!

Leuze Electronic offers the KRT 3B contrast scanner range with three different light transmitters - multicolor, white and red-light laser, providing a total of five transmitter colors. This unique scanner recognizes that the colors and surfaces of material can vary and have designed the latest product range to accommodate the variety of applications in which this device will be used.

Based on the differing requirements of industries, the transmitter models can be chosen to distinguish between grayscale values and color; or between specific colors; or for optimized differentiation of small marks and minimal contrasts, all while being superior devices.

With an average scanning range from 14.5mm and up to 60mm, and a quick response time between 50µs and 125µs (varies by model), this KRT 3B range does everything users need for reliable detection. All three transmitter models are available in an exceptionally small construction, making it the optimum choice for industrial situations with limited space for the machine.

Featuring YellowBoost technology that is developed exclusively by Leuze electronic and not found in any other product range, as well as other highlights such as three different light types, EasyTune adjustment, interoperable IO-Link, selectable teach variants and the fastest response time and resolution, the KRT 3B is small, dynamic, and unsurpassed as the contrast scanning product solution.

Contrast scanners are integral components of many automated production processes in today’s industrial environment and operate by using the difference in brightness between the mark and background to detect all kinds of contrasts at a constant scanning distance, such as color bars and tones and contrast marks on printed material, and are vital in situations where contrasts have to be detected quickly and accurately.
