*1. The sensing distance of E3C-LD11N is the value of the white paper.
*2. The sensing distance of E3C-LR[][]N is values apply when a E39-R12 Reflector is used.
*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-LR12N has a fixed beam size (the focal point cannot be changed).
