1. The range is obtained by measuring KEYENCE’s standard target (ceramic).
LK-G10/G15: When the sampling rate is 20 μs, the range becomes +0.37 (FAR side) to -1 mm (NEAR side).
LK-G32/G37: When the sampling rate is 20 μs, the range becomes +1.8 (FAR side) to -5 mm (NEAR side) for diffuse reflection, and +1.6 mm (FAR side) to -4.5 mm (NEAR side) for specular reflection.
2. The range is obtained by measuring KEYENCE’s standard target (ceramic) with the Standard mode.
3. The range is obtained by measuring KEYENCE’s standard (SUS) with 4096 times of averaging at the reference distance. The range in parenthesis is the typical linearity obtained by measuring the target with 16384.

When the sampling rate is 20 μs, the range becomes -9.06" (-230 mm) (NEAR side) to -9.84" (-250 mm) (NEAR side) for diffuse reflection.
When the sampling rate is 20 μs, the range becomes -9.06" (-230 mm) (NEAR side) to -9.80" (-249 mm) (NEAR side) for specular reflection.
When the sampling rate is 50 μs, the range becomes -4.92" (-125 mm) (NEAR side) to -9.84" (-250 mm) (NEAR side) for diffuse reflection.
When the sampling rate is 50 μs, the range becomes -4.92" (-125 mm) (NEAR side) to -9.80" (-249 mm) (NEAR side) for specular reflection.
2. The range is obtained by measuring KEYENCE’s standard target (ceramic) with the Standard mode.
3. The range is obtained by measuring KEYENCE’s standard (SUS) with 4096 times of averaging at the reference distance.
4. All are calculated at F.S. = ±9.84" (±250 mm).
5. “High accuracy range” and “long range” refer to the linearity when those ranges are used.
