^1 The range is obtained by measuring KEYENCE's standard target (ceramic). ^2 When the sampling rate is 20 µs, the range becomes -22 (NEAR side) to -40 mm (NEAR side) for diffuse reflection, and -22 (NEAR side) to -39 mm (NEAR side) for specular reflection. ^3 The range is obtained by measuring KEYENCE's standard target (ceramic) with the Standard mode. ^4 Consult your nearest KEYENCE representative for the Class IIIa type with increased repeatability. ^*5 The range is obtained by measuring KEYENCE's standard (SUS) with 4,096 times of averaging at the reference distance.
