    Specifications

    Model

    FS-N40

    Type

    Zero Line Type

    Main unit/expansion unit

    Expansion unit

    Response time

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

    Number of control outputs

    None*3

    Light source LED

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

    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

    Power 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 lx or less, sunlight: 30,000 lx or less

    Ambient temperature

    -20 °C -4 °F to +55 °C +131 °F (no freezing)*7

    Vibration resistance

    10 to 55 Hz; double amplitude 1.5 mm 0.06"; 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

    Weight

    Approx. 23 g

    *1 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.
    *2 Restrictions when HSPD is selected
    Display Gain cannot be used.
    *3 This counts as 1 output when connecting multiple units to the FS-MC8N/P, NU Series.
    *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 -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.
