Color sensors - Contrinex

The Series 4055 color sensors, for use in color-sorting processes and color control, feature three teachable color channels with independent 200-mA outputs, allowing three color tones to be programmed. The teach process offers five different tolerance levels. Small tolerances allow for minimal color differences to be recognized without fail and larger tolerances permit certain color variations. Color detection within the 30 to 40-mm operating range is virtually independent of target distance.
Additional features of the sensors include high switching frequency up to 4 kHz; 10-bit precision of R, G, and B signals; adjustable pulse delay and stretching. The sensors come in npn and pnp versions.
