1. The value is obtained by measuring KEYENCE’s standard target (ceramic).
LK-G10/G15: When the sampling rate is 20μs, the value becomes +0.37(FAR side) to -1mm (NEAR side).
LK-G32/G37: When the sampling rate is 20μs, the value becomes +1.8(FAR side) to -5mm (NEAR side) for diffuse reflection, and +1.6mm(NEAR side) to -4.5mm (NEAR side) for specular reflection.
LK-G82/G87: When the sampling rate is 20μs, the value becomes -9(NEAR side) to -15mm(NEAR side) for diffuse reflection, and -8.7(NEAR side) to -14mm(NEAR side) for specular reflection.
LK-G152/G157: When the sampling rate is 20μs, the value becomes -22(NEAR side) to -40mm(NEAR side) for diffuse reflection, and -22(NEAR side) to -39mm(NEAR side) for specular reflection.
2. The value is obtained by measuring KEYENCE’s standard target (ceramic) with the Standard mode.
3. The value is obtained by measuring KEYENCE's standard(SUS) with 4096 times of averaging at the reference distance. The value in parenthesis is the typical resolution obtained by measuring the target with 16384.
