The new Contrinex color sensors are well suited for color control as well as for use in color sorting processes. The devices feature 3 teachable color channels with independent 200 mA outputs, which allow for three color tones to be programmed. In addition, the teach process offers a choice of 5 different switching tolerance levels. Whereas small tolerances allow for minimal color differences to be recognized without fail, larger tolerances permit a certain color variation.
Due to the unique optics of the Contrinex color sensor, color detection within the operating range of 30 … 40 mm is virtually independent of target distance. Furthermore, the devices feature a high switching frequency of up to 4 kHz as well as an adjustable pulse delay and stretching.
The sensors are built into compact glass-fiber reinforced PBTP standard housings (40 x 50 x 15 mm) featuring insulation class II, a glass window and a connector adjustable to 0°, 45° and 90°. In addition to conventional methods of fixation by means of mounting brackets, these sensors can also be fixed with the help of a clamp bracket (dovetail groove).
