Sick  has supplemented its series of compact contrast scanners with a device version with a white light LED – the KT3M. The sensor’s highlights are its high switching frequencies of up to 10 kHz, space-efficient housing, static teach-in, and automatic self-learning for switching point and dazzle adaptation.

Prints and cutting marks (e.g. OMR marks) on the target object, e.g. a bag, tube or piece of printing, can be reliably detected irrespective of their size, because the white light transmitter of the KT3M generates a very fine consolidated light spot.

The white light LED in combination with various performance features makes the KT3M suitable for the packaging industry, for document handling or in printing machines. The compact housing is suitable for space-critical mounting conditions in machines.

Switching frequencies of up to 10 kHz and a response time of 50 µs also allow use of the sensor in high-speed applications. In switching outputs, the KT3M offers more options as the sensor has both NPN- and PNP-switching.

The KT3M is rapidly ready for use thanks to the possibility of simple and speedy teach-in, during which the correct setting is reported back to the operator. Contrast marks on highly reflective packaging as well as fluttering object surfaces are reliably detected with the automatic dazzle adaptation.
