| Degree of protection | IP67 |
| MTTFd | 620 a |
| Switching voltage | max. 30 V DC |
| Diameter of the light spot | approx. 0.6 m at 30 m |
| Switching type | light/dark on, switchable |
| Housing width | 25.8 mm |
| Threshold detection range | 40 m |
| Housing depth | 54.3 mm |
| Signal output | 1 push-pull (4 in 1) output, short-circuit protected, reverse polarity protected |
| 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 |
| Product standard | EN 60947-5-2 |
| Light source | LED |
| Alignment aid | LED red (in receiver lens) illuminated constantly: beam is interrupted, flashes: reaching switching point, off: sufficient stability control |
| Emitter | LD28-F1/76a/115 |
| Diagnostic Coverage (DC) | 90 % |
| CCC approval | CCC approval / marking not required for products rated 36 V |
| Response time | 0.5 ms |
| Ambient light limit | 50000 Lux |
| Operating voltage | 10 ... 30 V DC |
| Ambient temperature | -40 ... 60 В°C (-40 ... 140 В°F) |
| Receiver | LV28-F1/82b/110/115 |
| Operation indicator | LED green |
| 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. |
