Colour and contrast differences are important features for the detection and differentiation of objects. Sensors from SensoPart reliably detect coloured objects, printed marks or labels during production processes and quality assurance.

Our colour and contrast sensors are suitable for almost all relevant automation tasks thanks to their precise colour evaluation and high cycle frequency. SensoPart also offers a luminescence sensor for the detection of invisible luminescent colour marks.

Our vision colour sensors of the VISOR® Color series are particularly versatile. They offer very high colour selectivity and can also detect active (self-lighting) colours. The freely programmable Eyesight vision system offers even more comprehensive possibilities.

Detection of defined colour Detection of luminescent substances

Reliable colour detection:
The main task of the FT 25-C RGB colour sensor is the detection of a defined colour. It can also be used in very rapid applications thanks to its high switching frequency of 10 kHz.

Detection of invisible marks:
Luminescent substances can be detected with the FT 50-C-UV ultraviolet sensor. The presence of the label is checked on the basis of the luminophore it contains. The clever mounting bracket makes it very easy to mount and align the sensor.
