          *1 The range is obtained by measuring KEYENCE's standard target (ceramic).
          *2 When the sampling rate is 20 µs, the range becomes +1.8 mm +0.07" (FAR side) to -5 mm -0.20" (NEAR side) for Diffused reflection, and +1.6 mm +0.06" (FAR side) to -4.5 mm -0.18" (NEAR side)
          *3 The range is obtained by measuring KEYENCE's standard target (ceramic) with the Standard mode.
          *4 The range is obtained by measuring KEYENCE's standard (SUS) with 4,096 times of averaging at the reference distance.
