*1 The range is obtained by measuring KEYENCE's standard target (ceramic). *2 When the sampling rate is 20 µs, the range becomes -230 (NEAR side) to -250 mm (NEAR side) for diffuse reflection. When the sampling rate is 20 µs, the range becomes -230 (NEAR side) to -249 mm (NEAR side) for specular reflection. When the sampling rate is 50 µs, the range becomes -125 (NEAR side) to -250 mm (NEAR side) for diffuse reflection. When the sampling rate is 50 µs, the range becomes -125 (NEAR side) to -249 mm (NEAR side) for specular reflection. *3 All are calculated at F.S. = ±250 mm. 'High accuracy range' and 'long range' refer to the linearity when those ranges are used. *4 The range is obtained by measuring KEYENCE's standard target (ceramic) with the Standard mode. *5 The range is obtained by measuring KEYENCE's standard (SUS) with 4,096 times of averaging at the reference distance.
