^1The range is obtained by measuring KEYENCE's standard target (ceramic). ^2When the sampling rate is 20 µs, the range becomes -230 mm-9.06"(NEAR side) to -250 mm-9.84"(NEAR side) for Diffused reflection. When the sampling rate is 20 µs, the range becomes -230 mm-9.06"(NEAR side) to -249 mm-9.80"(NEAR side) for specular reflection. When the sampling rate is 50 µs, the range becomes -125 mm-4.92"(NEAR side) to -250 mm-9.84"(NEAR side) for Diffused reflection. When the sampling rate is 50 µs, the range becomes -125 mm-4.92"(NEAR side) to -249 mm-9.80"(NEAR side) for specular reflection. ^3All are calculated at F.S. = ±250 mm±9.84". ^4"High accuracy range" and "long range" refer to the linearity when those ranges are used. ^5The range is obtained by measuring KEYENCE's standard target (ceramic) with the Standard mode. ^6The range is obtained by measuring KEYENCE's standard (SUS) with 4,096 times of averaging at the reference distance.
