*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).

*1. This model allows you to use an E3X-ECT EtherCAT Sensor Communications Unit or E3X-CRT CompoNet Sensor
      Communications Unit.
*2. Communications are disabled if super-high-speed mode is selected, and the mutual interference prevention function
      and the communications function for the Mobile Console will not function.
*3. The following temperature ranges apply when an E3X-ECT EtherCAT or E3X-CRT CompoNet Sensor
      Communications Unit is used with the E3C-LDA0: Groups of 1 or 2 Amplifier Units: 0 to 55°C, Groups of 3 to 10
      Amplifier Units: 0 to 50°C, Groups of 11 to 16 Amplifier Units: 0 to 45°C, Groups of 17 to 30 Amplifier Units (with the
      E3X-ECT): 0 to 40°C.
