*1. Sensing distance values are for white paper.
*2. These sensing distance 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 focal point cannot be changed).
