          *1 For details on the detecting distance, see the fibre amplifier catalogue.
          *2 The minimum detectable object is the value when the detecting distance and sensitivity have been set to their optimal state.
          *3 Using this product in high-temperature liquids or steam may lead to penetration of the fluorocarbon polymers, which may cause fluctuations in the received light intensity and damage to the internal components.
          *4 Use this product under the condition that if the ambient temperature exceeds 60 °C, the absolute humidity is 60 °C 85 % RH or less.
