*1. Two sensor outputs are allocated in the programmable logic controller PLC I/O table.
      PLC operation via Communications Unit enables reading detected values and changing settings.
*2. Power consumption
      At Power supply voltage of 10 to 30 VDC
      Standard Models:
      Normal mode : 1080 mW max. (Current consumption: 36 mA max. at 30 VDC, 75 mA max. at 10 VDC)
      Eco function ON: 840 mW max. (Current consumption: 28 mA max. at 30 VDC, 55 mA max. at 10 VDC)
      Eco function LO : 960 mW max. (Current consumption: 32 mA max. at 30 VDC, 65 mA max. at 10 VDC)
*3. When connected to an OMRON NJ-series Controller.
*4. The tuning will not change the number of units.
      The least unit count among the mutual interference prevention units of E3NX and E3NC.
      Check the mutual interference prevention unit count and response speed of each model.
*5. The bank is not reset by the user reset function or saved by the user save function.
*6. When the number of connected units is 11 or more, the ambient temperature is less than 50°C.
