Contrast sensor: even more sensitive than before

Leuze electronic is expanding its product range with the new KRT 18B contrast sensor, an ideal combination of high performance and maximum usability.

The device uses three LEDs (red, green and blue), automatically determining the color producing the highest contrast with a scanned surface. It guarantees reliable detection on both glossy and dull surfaces thanks to automatic sensitivity adjustment.

The sensor is available in two versions: the first employs two teach buttons for bottom and surface calibration, while the other uses a potentiometer and a button for color selection.
The IO-Link interface enables quick and easy management of sheet format changes on the packaging machines.

A compact, tested ECOLAB IP67/IP69K housing and switching frequency up to 22kHz make the sensor particularly adapted for high speed production.
The sensor is supplied along with an accessory that enables aligning the 13 mm focal distance so that the sensor can be easily aligned for ready use.
