Popis produktu
Universal thru-beam sensor, large housing design, 30 m detection range, red light, 25 kHz transmission frequency, light/dark on, DC version, NPN output, PNP output, test input, pre-fault output, fixed cable
System components
EmitterLD28-F1/76a/115
ReceiverLV28-F1/49/82b/115
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 stability control
Transmitter frequencyF1 = 25 kHz
Diameter of the light spotapprox. 0.6 m at 30 m
Angle of divergenceEmitter 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 (function 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
Pre-fault indication output1 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 typelight/dark on, switchable
Signal output1 NPN, 1 PNP synchronized-switching, short-circuit protected, reverse polarity protected , open collectors
Switching voltagemax. 30 V DC
Switching currentmax. 200 mA
Switching frequency1000 Hz
Response time0.5 ms
