Technical parameters
| Emitter: | LD28-F1-3974/76a/112 |
| Receiver: | LV28-F1-3974/47/82b/112 |
| Effective detection range: | 0 ... 30 m |
| Threshold detection range: | 40 m |
| Light source: | LED |
| Light type: | modulated visible red light , 660 nm |
| Alignment aid: | LED red (in receiver lens) illuminated constantly: beam is interrupted, flashes: reaching switching point, off: sufficient stability control |
| Transmitter frequency: | F1 = 25 kHz |
| Diameter of the light spot: | approx. 0.6 m at 30 m |
| Angle of divergence: | Emitter 1.2°, Receiver 5° |
| Ambient light limit: | 50000 Lux |
| MTTFd: | 620 a |
| Mission Time (TM): | 20 a |
| Diagnostic Coverage (DC): | 90 % |
| Operation indicator: | LED green |
| Function indicator: | LED yellow: 1. LED lit constantly: signal > 2 x switching point (function reserve) 2. LED flashes: signal between 1 x switching point and 2 x switching point 3. LED off: signal < switching point |
| Control elements: | sensitivity adjustment (Adjustment to < 25% of the effective operating range) , Light-on/dark-on changeover switch |
| Operating voltage: | 10 ... 30 V DC |
| Ripple: | 10 % |
| No-load supply current: | Emitter: ≤ 50 mA Receiver: ≤ 35 mA |
| Test input: | emitter deactivation at +UB (Imax. < 3 mA at 30 V DC) |
| Pre-fault indication output: | 1 PNP transistor, short-circuit protected, protected from reverse polarity, open collector, Umax = 30 V DC, Imax = 0.2 A The output becomes inactive if the signal level has fallen below the function reserve for approx. 10 s (yellow and red LEDs flash). If the light beam is interrupted four times during this period, the output immediately becomes inactive. |
| Switching type: | light/dark on switchable |
| Signal output: | 2 PNP, complementary, short-circuit protected, reverse polarity protected , open collectors |
| Switching voltage: | max. 30 V DC |
| Switching current: | max. 200 mA |
| Switching frequency: | 1000 Hz |
| Response time: | 0.5 ms |

| Ambient temperature: | -40 ... 60 °C (-40 ... 140 °F) |
| Storage temperature: | -40 ... 75 °C (-40 ... 167 °F) |
| Housing width: | 25.8 mm |
| Housing height: | 88 mm |
| Housing depth: | 65.5 mm |
| Degree of protection: | IP67 |
| Connection: | Metal connector, M12, 5-pin, 90° rotatable |
