Ambient operating temperature –10 °C ... +50 °C Ambient operating temperature extended –30 °C ... +55 °C 10) 11) Ambient temperature, storage –30 °C ... +70 °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 = dark 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.
