          *1 IO-Link Specifi cation V.1.1/COM2 (38.4 kbps) is supported.
          *2 Ensure the cable length is 30 m 98.4" or less for the M8 connector type. Ensure the cable length is 20 meters 65.6' or less when connecting by way of IO-Link.
          *3 Output 2 and the external input are selectable.
          *4 Restrictions when S-HSPD is selected
          Output 2 of dual output types is fixed to OFF.
          IO-Link communication cannot be used.
          Area detection, Area % Mode, DATUM, Rising edge, and Falling edge cannot be selected for Detection Mode.
          Output timer, Limit Detection, and Display Gain cannot be used.
          FULL cannot be selected for the ECO function.
          *5 Restrictions when HSPD is selected
          Display Gain cannot be used.
          *6 The input time becomes 25 ms (ON)/25 ms (OFF) when external calibration input is selected.
          *7 When expanding the system to 9 or more units, use a power supply voltage of 12 V or higher.
          *8 The load current is excluded. The power consumption including the load when the maximum number of units are connected is 38 W max.
          *9 When expanded by 1 to 2 units: -20°C -4°F to +55°C +131°F. When expanded by 3 to 10 units: -20°C -4°F to +50°C +122°F.
          When expanded by 11 to 16 units: -20°C -4°F to +45°C +113°F. When using 2 outputs, 1 unit is counted as 2 units.
          The prescribed values for the ambient temperature assume that the sensor amplifi er has been mounted on a DIN rail installed on a metal surface.
          Exercise special care when installing the product in an airtight space.
