Thru-beam sensor LD28/LV28-F1-3974/47/82b/112

LD28/LV28-F1-3974/47/82b/112
  • Ultra bright LEDs for power on, weak signal indication and switching state
  • Highly visible LED as alignment aid in receiver optics
  • Emitter deactivation
  • Not sensitive to ambient light, even with switched energy saving lamps
  • Extra vibration proof version
  • Waterproof, degree of protection IP67

Please note: All product-related documents, such as certificates, declarations of conformity, etc., which were issued prior to the conversion under the name Pepperl+Fuchs GmbH or Pepperl+Fuchs AG, also apply to Pepperl+Fuchs SE.

Dane techniczne  LD28/LV28-F1-3974/47/82b/112

Opis produktu
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
EmitterLD28-F1-3974/76a/112
ReceiverLV28-F1-3974/47/82b/112
General specifications
Effective detection range0 ... 30 m
Threshold detection range40 m
Light sourceLED
Light typemodulated visible red light , 660 nm
Alignment aidLED red (in receiver lens)
illuminated constantly: beam is interrupted,
flashes: reaching switching point,
off: sufficient operating reserve
Transmitter frequencyF1 = 25 kHz
Diameter of the light spotapprox. 0.6 m at 30 m
Opening angleEmitter 1.2°,
Receiver 5°
Ambient light limit50000 Lux
Functional safety related parameters
MTTFd620 a
Mission Time (TM)20 a
Diagnostic Coverage (DC)90 %
Indicators/operating means
Operation indicatorLED green
Function indicatorLED yellow:
1. LED lit constantly: signal > 2 x switching point (operating reserve)
2. LED flashes: signal between 1 x switching point and 2 x switching point
3. LED off: signal < switching point
Control elementssensitivity adjustment (Adjustment to < 25% of the effective operating range) , Light-on/dark-on changeover switch
Electrical specifications
Operating voltage10 ... 30 V DC
Ripple10 %
No-load supply currentEmitter: ≤ 50 mA
Receiver: ≤ 35 mA
Input
Test inputemitter deactivation at +UB (Imax. < 3 mA at 30 V DC)
Output
Stability alarm output1 PNP transistor, short-circuit protected, reverse-polarity protected, open collector, Umax = 30 V DC, Imax = 0.2 A
The output becomes inactive if the signal level has fallen below the operating 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 typelight/dark on switchable
Signal output2 PNP, complementary, short-circuit protected, reverse polarity protected , open collectors
Switching voltagemax. 30 V DC
Switching currentmax. 200 mA
Switching frequency1000 Hz
Response time0.5 ms
