Specification
| Model | FS-N41N | |
| Type | Cable | |
| Output type | NPN | |
| Main unit/expansion unit | Main unit | |
| Number of control outputs | 1 | |
| Number of external inputs | ? | |
| Light source LED | Transmitter side: Red, four-element LED (wavelength 660 nm) | |
| 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) | |
| 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 |
| Operating ambient temperature | -20 °C to +55 °C (no freezing)*6 | |
| 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 | |
| Weight | Approx. 78 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 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. |
