*1 The range is obtained by measuring KEYENCE's standard target (ceramic).
*2 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 (FAR side) to -4.5 mm (NEAR side) for specular reflection.
*3 The range is obtained by measuring KEYENCE's standard target (ceramic) with the Standard mode.
*4 Consult your nearest KEYENCE representative for the Class IIIa type with increased repeatability.
*5 The range is obtained by measuring KEYENCE's standard (SUS) with 4,096 times of averaging at the reference distance.
