Contrast sensor

The contrast sensors FT 25-W and FT 25-RGB are up to 15 times smaller than conventional print mark sensors. Typical areas of application are print mark detection in the printing industry, e.g. in labelling and packaging machines, and in the food industry.

White-light contrast sensor and multi-colour contrast sensor for print mark detection

Contrast sensors are mainly used for printed mark detection in very rapid processes in the print and packaging industries. So it is all the more important that the energetic scanner used is absolutely reliable and does its job without problems. SensoPart offers precisely such "mark" sensors – with white-light LED (FT 25-W, FT 20WT series), red-light laser (FT 25-RL) or RGB diode (FT 25-RGB) options.
