Accessories Instruction manual

*1. The E3NW-ECT Sensor Communications Unit can be used, but the E3NW-CRT/CCL, E3X-DRT21-S, and E3X-CRT/ECT
      Sensor Communications Units cannot be used.
*2. The following details apply to the input.

Contact input (relay or switch) Non-contact input (transistor)
NPN ON: Shorted to 0 V (Sourcing current: 2 mA max.).
OFF: Open or shorted to Vcc.
ON: 1.5 V max. (Sourcing current: 2 mA max.)
OFF: Vcc - 1.5 V to Vcc (Leakage current: 0.1 mA max.)
PNP ON: Shorted to Vcc (Sinking current: 3 mA max.).
OFF: Open or shorted to 0 V.
ON: Vcc - 1.5 V to Vcc (sinking current: 3 mA max.)
OFF: 1.5 V max. (Leakage current: 0.1 mA max.)

*3. 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.
*4. Power consumption
      At Power Supply Voltage of 10 to 30 VDC
      Normal mode: 1,080 mW max. (Current consumption: 36 mA max. at 30 VDC, 74 mA max. at 10 VDC)
      Eco function ON: 840 mW max. (Current consumption: 28 mA max. at 30 VDC, 50mA max. at 10 VDC)
      Eco function LO: 930 mW max. (Current consumption: 31 mA max. at 30 VDC, 55 mA max. at 10 VDC)
*5. The mutual interference prevention function is disabled if the detection mode is set to Super-high-speed Mode.
*6. 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.
*7. The bank is not reset by the user reset function or saved by the user save function.

*1. These sensing distances are recommended to make the most of the detection capabilities of the Sensor.
*2. The Super-high-speed Mode for 12-color discrimination with a Reflective Sensor or for detection of translucent objects
      with a Through-beam Sensor can be set only in Contrast Mode. The Super-high-speed Mode can not be set in Color
      Mode.
