- Plastic fiber optic sensor for economical sensing in color mark and other low-contrast applications
- 15-turn potentiometer for manual adjustment of sensitivity
- 10 to 30V dc supply voltage with complementary NPN or PNP outputs, depending on model
- Normally open output for use as a diagnostic alarm for marginal sensing conditions
- Models with red, green, blue or white LED light source for color-differentiation applications
- LED indicators for power, output, alignment, sensing contrast and diagnostic warnings
