*1 For details on the detecting distance, see the fiber amplifier catalog.
*2 When this product is used in an environment with a consistently high temperature, we recommend a usage temperature of 130°C 266°F or less.
*3 Use in a dry state. Also, when using the heat resistant type, make a selection with ample room for the ambient temperature.
*4 The minimum detectable object is the value when the detecting distance and sensitivity have been set to their optimal state.
