*1 The range is obtained by measuring KEYENCE's standard target (ceramic).
*2 When the sampling rate is 20 µs, the range becomes -9 -0.35" (NEAR side) to -15 mm -0.59" (NEAR side) for Diffused reflection, and -8.7 -0.34" (NEAR side) to -14 mm -0.55" (NEAR side) for specular reflection.
*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.
