Documented Sensor Model
AESM00028SPO
RGB Colour Mark Sensor
Compact RGB photoelectric sensor for printed colour-mark and registration detection.
Representative imageOverview
AESM00028SPO uses an RGB light source to distinguish printed marks and contrast changes used for registration control. Its response time supports packaging, print, and web-handling applications where ordinary diffuse sensing may not separate the mark from its background.
Selection and setup should use the actual mark, background, web speed, and working distance.

Selection Notes
What to verify.
- Use when normal diffuse sensing cannot reliably distinguish printed marks.
- Confirm mark colour, background colour, web speed, and mounting distance.
- Final setup should use the actual print sample.
Before Quotation
Questions to answer.
- What is the mark colour and background colour?
- What is the web speed and required response time?
- Can an actual print sample be provided for setup?
