| *1 The range is obtained by measuring KEYENCE's standard target (ceramic). *2 When the sampling rate is 20 µs, the range becomes +0.37 (FAR side) to -1 mm (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. The range in parenthesis is the typical linearity obtained by measuring the target with 16,384. |
