Main unit/expansion unit

Main 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

1

Number of external inputs



Light source LED

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

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^*3

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^*4

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)^*5

Environmental resistance

Ambient light

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

Ambient temperature

-20 °C to +55 °C (no freezing)^*6

Vibration resistance

^*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 The input time becomes 25 ms (ON)/25 ms (OFF) when external calibration input is selected.
^*4 When expanding the system to 9 or more units, use a power supply voltage of 12 V or higher.
^*5 The load current is excluded. The power consumption including the load when the maximum number of units are connected is 38 W max.
^*6 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.
