| Aluminum die-cast; Weight | |
| Approx. 380 g (including the cable); *1 The range is obtained by measuring KEYENCE's standard target (ceramic). *2 When 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. *3 All 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. *5 The range is obtained by measuring KEYENCE's standard target (ceramic) with the Standard mode. *6 The range is obtained by measuring KEYENCE's standard (SUS) with 4,096 times of averaging at the reference distance. | |
