Note
1. Values are sensed for white paper.
2. These values apply when a E39-R12 Reflector is used. The MSR function is built-in. The reflected light from the object being measured may affect the sensing accuracy, so adjust the threshold value before use.
3. The beam radius is the value for the middle measurement distance and indicates a typical value for the middle sensing distance. The radius is defined by light intensity of 1/e2 (13.5%) of the central light intensity.
Light will extend beyond the main beam and may be affected by conditions surrounding the object being measured.
4. The E3C-LR12 has a fixed beam size (the focus point cannot be changed).
