Applications
Packaging, stickers industry: Label status, Mark color check, etc.
Electronic components, semiconductor industry: Defective unit check, Connector color check, etc.
General photoelectric sensor detects present or absent of target by light.
Color mark sensor detects colors of surfaces by RGB (red, green, and
blue) light source.
Saving the desired color at the inner memory, color mark sensor emits
RGB LED light source to the target sequentially.
Color mark sensor calculates ratio of the three colors, RGB, for the
optimized sensing via the inner light collection lens.
Using o󰀨-axis optical system for minimized optical loss, and cylindrical
lens, BC Series compares setting color and sensing color with full-color
determination.
