SICK CSM colour sensor

Click2Contact

The CSM colour sensor from SICK detects and monitors objects on the basis of their colour. The sensor is suitable for applications where colour characteristics need to be detected reliably and installation space is limited.

The small CSM colour sensor can be set using a simple teach-in method, while the IO-Link function enables intelligent diagnostics, visualisation of sensor parameters and straightforward format changes. Thanks to a switching frequency of up to 2 kHz, the CSM is also suitable for use with high-speed machines and manufacturing processes.

The sensor utilises single-colour LEDs (RGB) to blend together to match all colour hues. The light is transmitted to the object to be tested and the sensor calculates the colour coordinates from the reflected beam and compares these with the previously stored colour reference values. The technology is used in different applications such as packing detection without print marks, process control in the printing industry, the identification of tubes in the pharmaceutical industry and colour verification on sewing thread spindles.
