The new series of True Color Sensors SPECTRO-3…SLE is the consistent advancement of the SPECTRO- line. The performance of these new sensors is much better regarding efficiency, space-saving, operator convenience and economy compared with the former models. Types with focus optics, diffusor, polarising filter or fibre connector are available.
Beside of usual white light sources there are also versions with UV light to detect luminescent surface attributes. It is possible to switch between 2 absolute independend sets of parameters by software or input signal (2 in 1). 31 memory cells for colors (64 cells in group mode) provide a large flexibility for different tasks relating detection of color, contrast and greyscale. With a maximum switching frequency of 35 kHz these sensors are suitable for high process velocity, for example print mark checking. Noticeable are the small size (50 mm x 50 mm x 27 mm) and the M12 connector which reduces the diversity of accessories for the user.
