These reflectance sensors feature a linear array of IR emitter/phototransistor pair modules in a high-density (4 mm pitch) arrangement, which makes them well suited for applications that require precise detection of changes in contrast, such as line sensing. A variety of sensor counts are available so you can pick the ideal length for your application.
- Dimensions: 17.0 × 20.0 × 0.25 mm
