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.

1) Limit values when operated in short-circuit protected network: max. 8 A. 

2) May not exceed or fall below Uv tolerances. 

3) Without load. 4) Q = light switching. 5) Signal transit time with resistive load. 6) With light/dark ratio 1:1. 7) A = VS connections reverse-polarity protected. 8) B = inputs and output reverse-polarity protected. 9) C = interference suppression. 10) As of Ta = 50 °C, a max. supply voltage Vmax. = 24 V and a max. load current Imax. = 50 mA is permitted. 11) Operation below Tu –10 °C is possible if the sensor is already switched on at Tu > –10 °C, then cools down, and the supply voltage is subsequently not switched off. Switching on below Tu –10 °C is not permissible.
