1) Reflective tape REF-AC1000. 

2) To ensure reliable operation, we recommend using REF-AC1000 reflective tape or reflective-tap reflectors such as P41F, PLV14-A, PLH25-M12, or PLH25-D12. Reflectors with large-scale triple structures must only be used if deemed suitable for the application. 

3) Average service life: 50,000 h at TU = +25 °C.
