^*1 The AS-425K full scale is 0.5 to 1.0 mm (0.5 mm). The temperature characteristics refer to data when the temperature is in the range of +23 to +200°C.
^*2 When the distance between the sensor head and the target is within 50% of the measurement range.
^*3 The AH-809 is not constructed to be waterproof, so avoid using this product in an environment in which the product will be directly subjected to liquids or steam.
