1 The range is obtained by measuring KEYENCE’s standard target (ceramic). 2 When the sampling rate is 20 µs, the range becomes -70 (NEAR side) to -100 mm (NEAR side) for diffuse reflection. When the sampling rate is 20 µs, the range becomes -70 (NEAR side) to -99 mm (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.
