| Product Description |
|---|
| Universal thru-beam sensor, large housing design, 30 m detection range, red light, 25 kHz transmission frequency, light/dark on, DC version, 2 PNP outputs, test input, pre-fault output, M12 plug |
| System components | ||
|---|---|---|
| Emitter | LD28-F1-3974/76a/112 | |
| Receiver | LV28-F1-3974/47/82b/112 | |
| General specifications | ||
| 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 | |
| Opening angle | Emitter 1.2°, Receiver 5° | |
| Ambient light limit | 50000 Lux | |
| Functional safety related parameters | ||
| MTTFd | 620 a | |
| Mission Time (TM) | 20 a | |
| Diagnostic Coverage (DC) | 90 % | |
| Indicators/operating means | ||
| 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 | |
| Electrical specifications | ||
| Operating voltage | 10... 30 V DC | |
| Ripple | 10 % | |
| No-load supply current | Emitter: ≤ 50 mA Receiver: ≤ 35 mA | |
| Input | ||
| Test input | emitter deactivation at +UB (Imax. < 3 mA at 30 V DC) | |
| Output | ||
| Stability alarm 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 | |

| UL approval | cULus | |
| CCC approval | CCC approval / marking not required for products rated ≤36 V | |
| Ambient conditions | ||
| Ambient temperature | -40... 60 °C (-40... 140 °F) | |
| Storage temperature | -40... 75 °C (-40... 167 °F) | |
| Mechanical specifications | ||
| Housing width | 25.8 mm | |
| Housing height | 88 mm | |
