*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.
