1) Limit values when operated in short-circuit protected network: max. 8 A.
2) May not fall below or exceed 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.
