| Simple IR reflexive sensor. |
| [InfoShortDescription.cs] |
| Jednoduche reflexivni cidlo. |
| [InfoLongDescription.en] |
| [InfoLongDescription.cs] |
| Čidlo obsahuje pouze reflexní optron s odporovým trimrem a slouží k rozlišování tmavého a světlého povrchu. Dá se použít jak pro detekci čáry pro čárového robota tak i pro snímání otáčení pohonných kol. |
