          Main unit

          Number of control outputs


          Number of external inputs


          Light source LED

          Transmitter side: Red, four-element LED (wavelength 660 nm)

          Response time

          23 µs (S-HSPD*1*2) / 50 µs (HSPD*3) / 250 µs (FINE) /500 µs (TURBO) / 1 ms (SUPER) / 4 ms (ULTRA) / 16 ms (MEGA) / 64 ms (TERA)

          Control output

          Open-collector, 30 V or less 100 mA or less per output,
          100 mA or less total for 2 outputs (when used as a solitary unit) / 20 mA or less (when used as an expansion unit)
          Residual voltage: 1.4 V or less (output current 10 mA or less) / 2 V or less (output current 10 to 100 mA)

          External input

          Input time 2 ms (ON) / 20 ms (OFF) or longer*4

          Unit expansion

          Up to 16 units (17 units connected in total including the main unit).
          However, each dual output type will be treated as two expansion units.

          Protection circuit

          Protection against reverse power connection, output overcurrent, output surge, and reverse output connection

          Mutual interference prevention

          S-HSPD/HSPD 0 units, FINE 4 units, TURBO/SUPER/ULTRA/MEGA/TERA 8 units
          (The mutual interference prevention values are twice those shown here when Double is set.)

          Power supply

          Power voltage

          10 to 30 VDC (including 10% ripple (P-P) or less) , class 2 or LPS*5

          Current consumption

          During normal operation: 870 mW or less (34 mA or less at 24 V/62 mA or less at 12 V)
          ECO ON: 800 mW or less (31 mA or less at 24 V/56 mA or less at 12 V)
          ECO FULL: 710 mW or less (28 mA or less at 24 V/49 mA or less at 12 V)*6

          Environmental resistance

          Ambient light

          Incandescent lamp: 20,000 lux or less, sunlight: 30,000 lux or less

          Operating ambient temperature

          -20 °C to +55 °C (no freezing)*7

          Vibration resistance

          10 to 55 Hz; double amplitude 1.5 mm; 2 hours each for X, Y, and Z axes

          Shock resistance

          500 m/s2 ; 3 times each for X, Y, and Z axes

          Case material

          Main unit and cover: polycarbonate


          Approx. 83 g

          *1 Restrictions when S-HSPD is selected: Output 2 of dual output types is fixed to OFF.
          *2 Restrictions when S-HSPD is selected
          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.
          *3 Restrictions when HSPD is selected
          Display Gain cannot be used.
          *4 The input time becomes 25 ms (ON)/25 ms (OFF) when external calibration input is selected.
          *5 When expanding the system to 9 or more units, use a power supply voltage of 12 V or higher.
          *6 The load current is excluded. The power consumption including the load when the maximum number of units are connected is 38 W max.
          *7 When expanded by 1 to 2 units: -20 °C to +55 °C. When expanded by 3 to 10 units: -20 °C to +50 °C.
          When expanded by 11 to 16 units: -20 °C to +45 °C. When using 2 outputs, 1 unit is counted as 2 units.
          The prescribed values for the ambient temperature assume that the sensor amplifier has been mounted on a DIN rail installed on a metal surface.
          Exercise special care when installing the product in an airtight space.
