      • 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) Do not bend below 0 °C.
      • 8) A = VS connections reverse-polarity protected.
      • 9) B = inputs and output reverse-polarity protected.
      • 10) C = interference suppression.
      • 11) As of Ta = 50 °C, a max. supply voltage Vmax. = 24 V and a max. load current Imax. = 50 mA is permitted.
      • 12) 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.
