Color Mark Sensor
Feature
Outstanding color matching accuracy
- RGB light emitting diodes and 12-bit resolution
- 2 detection modes (color only / color + intensity)
- 3-step sensitivity adjustment for each mode (fine, normal, rough)
External light interference reduction minimizes errors and allows
stable detection
Check reference color with teaching indicator
Operation indicator (red LED), stability indicator (green LED),
timer indicator (orange LED)
Configure operation functions with external input from wiring
W1.24 × L6.7 mm spot size for detection of tiny targets and color marks
IP67 protection structure (IEC standard)

Specifications
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 off-axis optical system for minimized optical loss, and cylindrical
lens, BC Series compares setting color and sensing color with full-color
determination.
